Hello all, been a tad longer been a lot longer than I would have liked to have waited since the last post, my site has been having serious technical issue that prevented me from posting and uploading images. This post is kinda messy since I’m still figuring out what went wrong where, but here it is…
Some of you may remember that I haven’t posted about my Eublaberus sp. “Ivory” in a long time, not since this post back in the September of 2019. Since that time they were at first continuing to do “O.K”; with prolific roaches you hardly ever want them to just be “O.K”, and I was worried because adults were molting out but never producing any nymphs. This may have been because they were molting out staggered (I never had more than a few adults at one time), and the temperatures were low compared with what these like for breeding, but still I hoped to get some offspring out of them before the year was out. I switched them around my racks repeatedly to find the warmest spot, but they continued to molt out, hang around for a few months, then die. I was honestly very worried I was going to lose this species from my collection, as there were only so many juveniles and subadults left.
The new year rolled around, and all through the end of winter and then the spring the pattern repeated itself. I had several major (like nothing I’ve ever experienced) fly outbreaks during this time; first fungus gnats, then what looked like fruit flies (they weren’t), then a wave of another small fly I can’t figure out. It got so bad any drink left out would invariably end up with flies floating around within an hour, and if left overnight a mug with a tea bag inside could end up with 20+ flies at the bottom, trapped by honey residues or having suffocated, trapped beneath the tea bag and the mug wall. The second wave of flies quickly established themselves in with the E. sp. “Ivory”, and I began to notice dead adults infested with flies and fly pupa. I wondered whether these were the dreaded phorids, but it soon became apparent they were merely feeding off the already-dead adult roaches (still not a good situation). As soon as we hit summer though the flies started to dissipate (thank God!), and I noticed more adult Ivories were hatching out. My mind was elsewhere however as I dealt with a variety of other issues…
Until now. I checked the Ivories just a few days ago and was surprised to see small dots running around…small, brand new nymphs! I am absolutely floored that these have finally reproduced, ensuring their continued existence in my collection. In retrospect my earlier fears of losing them could have been ameliorated by providing the specimens with more heat and food during the winter/spring, but nonetheless it was a good lesson for me to learn, and in the end it turned out happily. I collected and counted out fourteen first instar nymphs before releasing them back in with the subadults/adults, but I am positive there are more that I missed (the enclosure is a medium Sterilite bin with about 3-4 inches or 7-10 centimeters of substrate), and a few of the adult specimens looked noticeably swollen, so…
The new nymphs are basically miniatures of older ones, and just as active. Pictures were difficult to attain due to this behavior and a proclivity to instantly dive into the substrate if given the opportunity.
Now, in the intervening time when I wrote the above and was trying to figure out what in the world was messing with my site, I gave my roaches, including the E. sp. “Ivory”, some dry cat food. Nothing wrong with that right? Well, turns out this cat food contains DL-methionine, an “organic” pesticide that is harmful towards insects with alkaline guts, i.e mosquitos and, you guessed it, roaches. I found this out less than hour after feeding almost all my roaches the cat food. So, back to the bins I went, pulling out the food and throwing in carrots to dilute whatever had already been consumed. I’m hoping there will be no long-lasting affects, as the pesticide doesn’t often kill all specimens immediately but rather weakens and then kills them over time, but that remains to be seen.
Hello all! Today we once again have post that is a bit different from the usual collection update. Instead, I present to you an interview with Declan Hegge AKA RezonantVoid from Arachnoboards!
For those of you who don’t know, RezonantVoid is one of the premier Australian invertebrate enthusiasts. Besides maintaining a collection containing many of the native Australian species of tarantulas across all four known Australian genera (Phlogius, Selenocosmia, Selenotholus, and Selenotypus), he also keeps a wide array of non-tarantula mygalomorphs, scorpions, centipedes, and various other invertebrates, to go with a few species of reptiles. He is mainly active on Arachnoboards, where he teases shares his knowledge and photos with us foreign enthusiasts, while also dialoguing with and helping the many other Australian enthusiasts to be found on the forums.
I reached out to RezonantVoid during the Australian bushfires catastrophe, which we discuss a little in the interview, and he granted me permission to ask him a few questions. So without further ado, here is my conversation with him.
Arthroverts: “How did you originally get into the hobby?“
RezonantVoid: “Okay so I guess to kick off, inverts have always for whatever reason held a special place in my heart since I was literally 4 years old. Ever since I can remember I’ve always been flipping rocks and logs, seeing what I could find underneath. But what really got me started on becoming a dedicated hobbyist was discovering “The Dark Den” on Youtube in late 2017. I’d been casually keeping a handful of scorpions since 2008 but never as a serious hobby, yet watching his video just fanned the spark of enthusiasm I had into a blazing inferno.
I can’t remember the exact dates, but I’m pretty sure by mid or late January 2018 I had my first 3 T slings (I’d unsuccessfully kept a few slings in the past but this time I was determined to get it right), and before I knew it I had like 11 T’s across all 4 described native genera. My first time dealing with trapdoors was rescuing a bunch from a job site before a [concrete] slab got poured, and I fell in love with them so much that I primarily shifted to keeping our non-tarantula primitive species, going on eventually to mouse spiders and Atracids.”
Euoplos turrificus. Simple coloration does not always make for an unhandsome specimen, as exhibited by this specimen.
A: “What is it about invertebrates that so interests you?“
RZ: “I can’t really say there’s any one specific thing that makes me feel drawn to them. I will say though, that a truly massive part of my interest in wildlife as whole came from Steve Irwin. As a kid we had almost every one of his films on DVD or even video tape (far out, times have changed!), I swear I must have watched those things almost daily. He taught me and no doubt many others that our wildlife is not all dangerous, just grossly misunderstood. That’s a lesson I’ve taken with me ever since and almost certainly a big part of why I ventured into inverts despite most people’s reactions. You can gaze at them for hours and learn something new just about every time. And of course, nothing can surpass the elation of opening a burrow to find hundreds of tiny spiderlings inside and realizing that pairing 6 months back was indeed successful.”
A: “Do you think that being an enthusiast in Australia, decidedly limited in the exotic species available, ha ha, has either helped or hindered you in your hobby journey? Does the plethora of native Australian species make up for it you think?“
RZ: “Lack of exotics was a roadblock I hit very early on and admittedly I did get very down about it. Next day I read an article about our unnamed floodplain tarantulas in the northern territory that spend months underwater. I was asking for stuff out of reach when I had insane critters right under my nose that I had no clue even existed. I really went all out researching at that point, pretty sure around March-July 2018 almost constantly studying our described native Mygalomorphae, and let me tell you, its crazy how many we have. Between Nemesiidae, Atracidae, Idiopidae, Barychelidae, Migidae, Theraphosidae and probably 20 others I forget, the number of species offsets the lack of exotics 10 fold. in fact, I would go as far as to say living here is the hobbyist dream. Name one other place where you can go to just about every untouched piece of bush and find multiple species of primitives that most likely aren’t even described! If I could have bought things like Brachypelma and Poecilotheria, I can guarantee I would never have had the variety I have now.”
Aname sp. “Gold”
A: “Even so, is there a foreign species that you wish you were able to keep?“
RZ: “That question is quickly summed up with Linothele megatheloides.”
A: “What is your favorite species you’ve kept? Is there still a “Holy Grail” species you’re searching for?“
RZ: “Its a very tough choice but I’d have to narrow it down to either Hadronyche formidabilis or Idiommata sp. “Silverback/Electric Blue”. Both are my top 2 rarest species and have me checking their containers first up every night.
Right there’s a holy grail species, Xamiatus magnificus. The world’s largest known wishbone spider. It is so rare that no photos of it exist online, but there are a few of Xamiatus rubifrons, a very similar looking smaller species. I actually know where the latter are found but haven’t had the opportunity to visit yet. I’m honestly not sure if I will ever find it, but I’ll absolutely keep looking.
Hadronyche formidabilis. The deep black is strangely attractive. Much more so than anything Grammostola pulchra can offer anyway.
A: “How large is your collection? Do you see it growing further in the future?“
RZ: “My collection is actually way smaller than I originally thought, unfortunately I lost a few species recently. Probably at around the 60 or so permanent members mark. I’ll definitely be trying to grab a few more things soon though, in particular from the Nemesiidae.”
Namea salantiri. Gorgeous coloration on this specimen.
A: “We’ve all heard about the Australian bushfires, but how has it affected you and the Australian front of the hobby?“
RZ: “I know others including at least one other Arachnoboards member who have been directly impacted, but if I’m honest I personally have been largely unaffected to this point. I live outside the fire grounds, but not 2 hours south of me the Coffs Harbor area got really badly scorched. Unfortunately this area is home to a massive diversity of araneofauna including some species that are almost never seen by members of the public, such as the genera Xamiatus and Ixamatus. I know one private property in that area (luckily I think the fires missed it) with the following species just in their front and back yard: *Aname/Namea sp. *Australothele nambucca *Australothele jamersoni *Missulena bradleyi *Hadronyche macquariensis *Ixamatus webbae *Arbanitis sp. “Coramba” 1 & 2 *Xamiatus ilara
So there are places quite close to me that have suffered significant loss, especially amid wandering male season, but not me. Worst we’ve had is extensive smoke blanketing our town but my inverts don’t seem ‘badly’ affected yet by it.
However, the absurdly high temperatures also call for massive shipping delays with inverts, and I even got my first thermally insulated box with a cold pack the other week haha. Breeding efforts in captivity will surely have slowed down too, prices go up as does demand, and more species get impulse collected from the wild by panicking collectors. I would say that increase in collecting most definitely affects all major invertebrate groups, but since spiders are considerably easier to locate and capture than scorpions and centipedes I would have to guess they are being hit the worst.
A picture of the havoc taken near Declan’s abode. The white marks on the ground are where a tree was literally reduced to nothing but ash.
A: “Are captive breeding efforts the only remaining hope for some species who have had their native locales destroyed?“
RZ: “I think this is quite an accurate statement. From my perspective, I’ve already seen a handful of colonies obliterated, with the greatest effect being on lidless trapdoors like Arbanitis. I’m sure a regular low intensity bushfire would normally be quite survivable, but we are talking drought fueled megafires over 30m (90ft) tall that vaporize just about everything. One locale about 40 minutes away was reduced to nothing more than charred burrows with a few exoskeletons inside.
Let’s say a fire goes through a 10,000 strong colony spread over 1 square kilometer, and wipes out half of them. 5,000 is still a lot, but that number may take decades to replace the original numbers. Ants are the quickest insects to bounce back from a fire, which aren’t the most nutritious food for growing slings. Many slings may even get eaten while trying to catch them, due to a lack of other available prey.
So what happens to colonies reduced to mere hundreds or less? Depending on how spread out the survivors are, the 3 day average lifespan of male traps in the wild is hardly enough time to pair with a female. In such a case, captive breeding is almost 100% the most effective way of repopulating, being able to guarantee the survival and growth of every individual sling from an egg sac. Saddest of all though, while the fires have indeed stopped, is for many species this has come too late. National parks are a great way to keep wild populations safe, but in my opinion there is no point in doing so if you don’t have backup populations in captivity. I hate to think of the hundreds of species lost this summer in such areas because nobody was allowed to secure a handful of individuals prior to the fires”
Burnt-out Arbanitis sp. burrow.
A: “Do you think the Australian government will change the regulations in regards to this at all?“
RZ: “I have to say I strongly doubt it. The vast majority of attention has been given to protecting Koalas and other mammals which while are definitely important to conserve, are not the baseline of the ecosystem. Very little regard is given to invertebrates down here other than by hobbyists and scientists. I was actually really impressed to see there was one single news article that did mention how we need to shift a lot of attention to protecting invertebrate fauna, but it was very brief. With their attention fixed on “bigger” issues, I can’t see politicians making any adjustments to current national park laws allowing more people to establish captive populations. You can apply for Scientific Collection Licenses but the aim is more for studying specimens and less about conserving them. I also believe you need prior qualifications to obtain one but I hope I’m wrong. In any case, I think some of even the more commonly available species in the hobby here have become a heck of a lot more important to keep established and hybrid free in case there is a need for wild release in the future.”
Scorched forest areas. These photos were taken a few weeks after the fires went out, hence the new green growths on the trees (gumtrees have specially designed, fire-resistant branches, allowing them to kickstart the process of regrowth in regions ravaged by fire).
A: “How can we foreigners help? Is sending money and raising awareness enough?“
RZ: “It’s difficult to say exactly what effect overseas funding would really have, because there aren’t a lot of organizations that could use it efficiently for its intended purpose. Nearly all hobby species here come from regular civilian enthusiasts going out collecting, and the majority of hobby expenses come from the exact same things as anywhere else (such as buying feeders, enclosure supplies and whatnot). It’s not like a ton of hobbyists can just throw up their bank details online and expect heaps of people to donate them money “for the conservation of critters affected by the fires”. I’m sure there are many other groups here that care for general animals hurt by the fires (like koalas, possums, native birds, and the like), and for the time being any willing donations are probably best spent on them until an organization arrives that pays veteran collectors to gather endangered inverts for captive breeding.
From my perspective, the best thing everyone can do to help our inverts, is simply spread the word about their importance and share our love for this wonderful hobby. Only by raising more awareness of how essential they truly are to everyday life, regardless of how scary they may appear, can we squash the stigma people have about inverts, and not inverts themselves.
While I would never wish this dreadful virus on anyone, I think its actually going to be interesting to see how quarantine has benefited various insect populations worldwide. With less traffic on our roads, late blooming mature males and flying insects are less likely to get hit by cars, meaning more of them successfully make it to a female. Maybe this short breather after the fires here is just what they need to get back on track to repopulating lost habitats. All we can do is hope.”
A: “Hope is indeed something we could all use right now, whether it be for humans or animals.“
Arbanitis sp. “Coramba”
I’d like to thank RezonantVoid for agreeing to do this with me. If you’d like to help but don’t know how, remember what he said; “Only by raising more awareness of how essential they truly are to everyday life, regardless of how scary they may appear, can we squash the stigma people have about inverts, and not the inverts themselves.“
If you have further questions, don’t hesitate to reach out to me or RezonantVoid. Only together can we work towards conserving species, in Australia, the US, or wherever you are.
“For we know that the whole of creation groans and travails together until now.”

Now obviously, I just made that up, but it does seem very applicable for the title of this post.
Anyway, welcome once again! Short post today, but I shall reveal my much-speculated (not really) blatticomposting project.
What is blatticomposting? In a nutshell, it is basically composting with cockroaches. Not only is it faster than traditional composting methods, it is also exceedingly more efficient and hygienic than the similar vermicomposting, or composting with worms, as blatticomposting bins do not acquire a strong odor and will rapidly turn large amounts of leftovers into soil (quite unlike most worms which will take weeks to eat any large amounts of food). It is usually carried out with members of the genus Eublaberus, most often sp. “Ivory”, though for this project I decided to experiment with Eublaberus serranus, because A) I already have E. sp. “Ivory”, and B) The E. serranus were a lot cheaper. Those of you who know me well enough will realize option B had a disproportionate effect on my decision.
Anyway, after months of attempting to get this off the ground, I finally worked it out. The 119-something (ordered 100) specimens I received from The Invert Shop all arrived safe and sound, and they went straight into their enclosure upon arrival. For this project I decided to go with a bucket cage, which is exactly what it sounds like: a 5 gallon gasket-seal bucket. I did not drill ventilation holes, mainly because I was simply too busy to deal with it at the time, so the lid isn’t fully screwed on at any time; thankfully this species is incapable of climbing smooth surfaces and isn’t arboreally-inclined as it is. Two heat pads were taped to the sides of the bucket to provide heat, as I got these back in the frigid winter months, though I have since removed them as the temperatures in the room the roaches are kept in has climbed a full 10 degrees Fahrenheit to the 77-78F range. I originally was using a substrate made up of coco fiber, filled up to about 4-5 inches from the bottom, with a medium-sized branch sticking up out of it as the adults need space to escape the ever busy juveniles. However, I learned the hard way that a full piece of melon can turn a gallon of substrate into a perfect, anaerobic swamp. As I don’t keep swamp invertebrates (yet) I pulled the roaches out, which had collected in the upper regions of the enclosure, and threw the substrate out. I also discovered that in this process the lower portion of the branch had rotted (helped along by the gnawing of the juvenile roaches) from the excess moisture, and broken off.
After removing the offending substrate, I replaced it with a mix of coco fiber, aspen shavings, and some rotting leaves; a month or so into this and the shavings and the leaves have rotted/been eaten, which is what I had anticipated. The branch, though significantly smaller, went back in, and has fared better than its other half insofar.
Food has consisted of vegetable and fruit table scraps, as well as more typical fare, like dog food, and some more unusual items, such as scrambled eggs and old oatmeal, which though eaten completely, were not received with as much gusto as I thought they would be. I taped a piece of paper to the side of the bucket to help keep track of what food went in, how many individuals were left, etc., but my record keeping has completely failed on this front.
The summer warmth has meant though that quite a few specimens have molted out to adulthood, though they are less colorful as adults than I originally anticipated. Not the best pictures below, these fellows can be a pain to photograph as they try to get back down into the substrate. Any movement of the bin inevitably sends them scurrying back into their dens as well, so pictures of them in the enclosure need to either be done rapidly or gotten by leaving the lid off and throwing food in.
Adult specimen. The adults will walk-run frantically around your hand in a bid to escape.
Large nymph/sub-adult. These can be a pain to photograph in another way; literally! The formidable spikes that Eublaberus sp. come equipped with, while perfectly made for digging, do not make handling a comfortable experience.
Photo of the masses feeding on oatmeal. Lowering ones hand into the bin without disturbing them makes for a fine trick.
Video of the emergence…surprisingly not as riotous as I thought it would be. Then again, oatmeal isn’t a particularly exciting food for any of the roach species I’ve kept (just like some people in that regard I guess!).
And that’ll do it for now! I’ll catch y’all next time. I have a very special post coming up, so stay tuned!
Hello all, this time we are jumping tracks in terms of posts, and I am happy to present you my interview with Tristan Shanahan AKA TJ Ombrelle AKA Hisserdude AKA Invertebrate Dude (that’s a mouthful)!
Tristan is one of the premier invertebrate enthusiasts in the US, focusing mainly on roaches, but also with experience in a wide variety of other invertebrates. His blog has served as a source of credible information and experience for more than five years, and, fun fact, was one of the inspirations for this blog itself! Needless to say it was only a matter of time before I would try to get the scoop (so long as he agreed…) on this contributor to the invertebrate hobby.
And so, without further ado, I present to you my interview with Invertebrate Dude and a few photos of his specimens, past and present!
Arthroverts: “How did you get into the hobby?“
Invertebrate Dude: “I’ve always been interested in wildlife, from a very young age, with a particular fascination for animals often perceived as “gross” or “scary” to people, prime examples being cockroaches, snakes, Suriname toads, hagfish, etc. I was always out catching various invertebrates, (roaches were a favorite), sometimes keeping them in jars and such temporarily. I was around 9 years old when my grandfather, (who kept and bred ball pythons and other reptiles), gifted me a male Madagascar hissing cockroach, (a Gromphadorhina hybrid), and I believe that’s what really kick-started my love for keeping invertebrates in captivity long term. Over the next couple years I started getting more males of other hisser species, and then started attempting to keep and breed almost every US native or adventive invertebrate I could find. A few years later I started keeping breeding groups of exotic roaches for the first time, and that’s when I founded my blog. :)”
A: “Over the years as you have detailed your experiences in the hobby on your blog, there has been a noticeable shift in your interest towards roaches; what is it about these insects that so captivates you?“
ID: “To be honest, I’m not really sure, for some reason I’ve always loved animals the world loves to hate, and roaches are one of the most misunderstood insects out there. Periplanetaspp. were also a common sight in the areas I lived as a younger child, and having such large, non-biting insects to catch and handle often probably helped me develop a love for roaches early on. As for keeping them as pets, roaches are pretty easy to maintain, even most of the more difficult ones are relatively simple to set up compared to many other invertebrates, they’re also a very diverse group, and this is reflected in the array of species available in the hobby. I’d say those are the two major drawing factors for roaches that I can’t resist. “
Lanxoblatta rudis nymph, an incredible South American species that precariously exists here in the US in the hands of a few breeders. Easily one of my favorite roach species, I hope to one day acquire them and get them firmly established here, though by that time I hope they already are…
Lanxoblatta rudis adult. The texturing on this species is incredible…
A: “What do you have in your collection currently? Do you think it’ll grow further?“
ID: “I currently have two roach species, (Gyna capucina, Bantuasp. “Namibia”), three darkling beetle species, (Eleodes nigrina, E. obscura, E. sp. subgenus Blapylis), and I have some interesting click beetles on the way as well. I was planning on keeping my collection down to ten species, but I’m not sure if I’ll be able to adhere to that. I definitely won’t be keeping anywhere near 100+ species like I did in the past though, and several of the species I’ll be keeping will be on a temporary basis, just to help get them established in the hobby. “
Gyna capucina specimen, a more finicky species in the genus, and one of the two species of roach Invertebrate Dude is currently keeping. Look at those colors!
Eleodes obscurus, a rare Eleodes species within the hobby.
A: “Do you have a favorite species/genus?“
ID: “Hands down, my favorite genus is Pilema, a weird genus of cockroach that spends most of it’s life in a neat round burrow dug into hardened clay. They may look boring to some people but I absolutely love their weird habits, they’ll eat decaying organic matter around their burrows, and mothers will keep their offspring in their burrows for at least a molt or two, often building up little “chimneys” to accommodate them all. I actually had plans to acquire a Pilema species this year, but unfortunately I may not be able to period, thanks to the pandemic…”
A: “Is their still a “holy grail” species that you’d like to one day acquire?“
ID: “I’d really like to try my hand at Archiblatta hoeveni, they seem like they’d be easy enough to breed if consistently given proper care, just so long as one took into account their solitary and arboreal nature. The closely related Catara rugosicollis would also be nice to work with.”
A: “You have talked quite a bit about the importance of conservation (such as in your post on Platerodrilus sp. beetles), both in captivity and in the wild, of various invertebrates. Where do you see the hobby being in this regard?“
ID: “I see the hobby as potentially being very helpful in the conservation of many species, but also being detrimental to the conservation of others. Some species, particularly of well known and commonly kept orders, can often easily be kept and bred long term in captivity, and if they’re pretty or interesting enough, usually a wide variety of people will want to keep them, thus cementing their place in captive breeding. However, I believe that other, less studied organisms, ones that have traditionally done very poorly in the pet hobby like trilobite beetles and Madagascan pill millipedes, should only be kept by zoos and labs until adequate, repeatable husbandry methodologies can be produced, after which introduction to the pet hobby could potentially be very beneficial. Unfortunately where we stand right now, there is next to no effort from professional labs or institutions to successfully cultivate most invertebrates, so the pet hobby can be hit or miss when it comes to conservation. Sometimes we can save species from extinction or eliminate collection pressure for some species with captive breeding, other times we can actually harm wild populations with excessive collection, which is normally only a problem with species that are extremely difficult to keep or species no one even tries to breed (like Emperor scorpions, Chilean rose hair tarantulas, etc.). In my opinion we should strive to successfully breed as many species as possible, and thus greatly reduce or eliminate the collection of wild individuals of said species. For those that we can’t seem to breed after dozens of tries, giving up and fighting instead for conservation of their wild habitats may be the best course of action.”
Panchlora sp. “White”, another amazing, maddeningly-sensitive species that has also gone the way of Arthopleura in the US…
A: “Where do you see yourself in the future in this hobby?“
ID: “I hope to continue to get enjoyment from this hobby, help establish as many species as possible in captive culture, and be a reliable source of husbandry information for newbies and experienced breeders alike.”
A few of you may recognize this amazing photo capturing the bioluminescent glow from a Pyrophorus noctilucus, a species of elaterid beetle formerly kept by Invertebrate Dude. Truly an incredible specimen. Can’t wait to see what new species of elaterids you are getting Tristan!
A: “Do you see yourself continuing to dial in on roaches or perhaps expanding into other invertebrate groups once again in the future?“
ID: “I think I’ll probably keep honing in on rare roaches for the time being, (I say as I currently have more beetles than roaches), but branching out is bound to happen, I’m sure I’ll be keeping some non-roach oddball inverts in the future, though they will have to be true oddballs or otherwise very remarkable to earn a place in my collection.”
Psytalla horrida adult. Big. Colorful. Expensive.
A: “Finally, do you have any tips for an aspiring blatticulturist like myself?“
ID: “So long as you’re consistent with your care, start out with widely recommended beginner species, and are sure to get husbandry information from not just one, but several trusted sources, there’s almost no limit to the species you should be able to breed in this hobby! Also, pro tip, if something goes wrong and a colony crashes for seemingly no reason, just know that while inbreeding is usually the big bad boogeyman people point their fingers to first, inbreeding’s almost never actually the cause. Pro pro tip, large, prolific springtails and many isopods can actually be as detrimental to roaches as grain mites can, so be careful what you use as cleaner crews.”
Hormetica strumosa adult. A site to behold that alas, is quite rare in the hobby…
Huge thank you to Tristan Shanahan AKA Invertebrate Dude AKA…you know who he is…
Anyway, again, thank you Tristan for sharing your knowledge and photos with us! I greatly appreciate it, and look forward to seeing you continue to share your knowledge, experience, and pictures with us on your blog and elsewhere. If you want to see all of Invertebrate Dude’s content, check out his blog here, his YouTube channel here, and his forum activities here, here, and here.
Surprise L. rudis profile photo!
That’s all for now, catch ya on the flip side, or if I’m not there, look for me outside wherever there is creation and invertebrates!
Hello all! Just a short post for today, but I have been sitting on, as the title says, quite a lot of photos (as well as a few updates), including some of a few new additions, so let’s bring them out of storage!
Damon medius. One of two 4th instar juveniles I received from my amblypygid enthusiast/breeder friend. These were captively bred from wild caught specimens, not born of an already-inseminated wild caught female (that’s a mouthful).
To show the scale of the specimen. This specimen and its sibling are only two instars off the mothers back, but already they are larger than all US-native species! Except of course for maybe the mythical Acanthophrynus coronatus…
To give one an idea of finding Apomastus, find this, which is less than 1/3 of an inch (0.84 cm) across…
Pause for a short update on my diplopods:
My millipede collection has been in a state of flux, with the disheartening loss of three Spirostreptidae sp. “1”. However, I did acquire four large immature Apeuthes sp. specimens and four Trigoniulus macropygus, which are currently too small to photograph properly, as well as three Bollmaniulus sp., a small native julid with a very interesting grey-green pattern. I also discovered my Anadenobolus monilicornis have kept right on trucking despite multiple rehousings in the past few months, and I estimate I now have over a hundred specimens of various. My remaining Narceus gordanus seem to be doing relatively well, as does my Spirostreptidae sp. “8”; if only I could find a mature male for her!
Lastly, the mystery millipede I mentioned a post or so back has grown considerably in size, to close to 2.5″. With every molt it looks more like Tylobolus claremontus; how that could be, I have no idea.
Abrupt ending alert.
And that will bring to the end of this photo journey, at least for now. As always I seem to have a backlog of information to post about, so that by the time I get around to posting about Apomastus kristenae for example I need to update y’all on Eublaberus s…hah! You won’t weasel that update out of me early!
Hello all! As probably none of you know (;), I have been eying crabs for a while now. No, not your typical hermit crabs or other marine aquarium crabs, though those are awesome too. Rather, my interest has grown in freshwater/brackish terrestrial crabs, specifically of the genus Geosesarma.
Bam! Surprise Photo.
I have always had an interest in these fascinating freshwater denizens, but doors started to open in regards to their availability after I saw a 1:1 pair of vampire crabs come up for sale/trade on Arachnoboards. I eagerly contacted the seller, and soon we had a trade worked out. Unfortunately, one of the specimens died before we shipped out, and since I was primarily interested in breeding them (which you can’t do with only a male), the trade fell through.
However, sometime after, I discovered one of my friend’s, also interested in the obscure invertebrates of the world, already had two species of Geosesarma! He let me know that he was able to order more, and that if I wanted some to let him know. Long story short, I ended up with 5 Geosesarma dennerle, two females and three males (the shipment was male-biased), of an odd color variation! They seem to lack a full splotch of yellow on their carapace, a usual characteristic of G. dennerle, rather appearing to somewhat retain their juvenile coloration of just splotches of yellow/whitish-grey. Then again, a few of the specimens still are juveniles starting to transfer into adulthood, so we’ll see how it pans out with them.
Geosesarma sp. definitely are on the small side, and all of my specimens are only about 1.5″ in terms of leg span (that’s about 3.81 cm for all you people on the metric system), but what they lack in size they make up for in coloration, behavior, and ease of breeding. They are one of the few crab genera to breed fully in freshwater, with the females giving birth to fully-formed baby crabs! They also are very communal, making it even easier to breed these awesome crabs in captivity.
I already had an empty 20 gallon (75.70 liters) paludarium, purpose built for vampire crabs a few months before by my insanely-skilled brother, calling for some inhabitants, so I’m sure you can guess where they are being housed…photos below!
The paludarium. A small water feature, kept moving by the small waterfall of sorts coming out of the rock on the left, is kept hard by the presence of calcium carbonate coral sand and a few coral rocks. Soft water will lead to deformities in the crabs.
On land there is a plethora of plants, Cissus discolor, Selanginella sp., Pepperomia rosso, Epiperemnum aureum, and various other unknown plants in both the soil and in the water. My skill with plants is not where I’d like it to be yet…
Everything has been happy and growing, with one plant even flowering. The crabs have done quite a bit of rearranging however, including exposing the tubing and blue foam underneath the substrate in several areas. Also, besides eating their regular food of springtails, dwarf isopods, and biodegradable peat pots (a trick shared by the above mentioned friend), they have also decided they like the taste of both decaying and growing moss, and the leaves of the fern in the back left of the second paludarium photo. They crawl up the leaves of what looks like a lemon plant in the mid-left of the same photo, and then strip off the low-hanging fern leaves. Considering this fern has been the most sensitive and difficult plant to get growing, I can only say that I am mildly frustrated with their sudden favorite food. But just so long as the crabs are happy, I’m happy, ha ha.
And there you have it! My crustacean adventure as of now. My plan is to breed them if you haven’t picked that up yet, and hopefully start to increase the numbers of captive bred specimens available in the hobby. Hopefully by doing so more species will come into the hobby, including two of my favorites: Geosesarma borogensis and G. malayanum.
As always, I thank God for all these incredible creatures to marvel at. The diversity He created is truly breathtaking.
Ah, you didn’t think I’d make a January post, did ya now? Well, I did, so let’s get on to the cool part…
Well, I started this in January…
January has been kinda all over the place for me, just like this post will likely be. The celebration of the Invertebrate Club of Southern California’s 1st Anniversary meant I came home with quite a few invertebrates, and then a few collecting trips meant I came home with a few more+a lot of rotting leaves and wood for my detrivorous charges. Unfortunately I seem to be continuing my theme of gaining species only at the loss of something else…
Anywho, let’s start with the new stuff. I traded for one new species of isopod and one new morph, Porcellio scaber “Koi”, a species I seek to redeem myself with, and Porcellionides pruinosus “Powder Orange”.
Continuing with isopods, Some Time Ago, at a Reptile Show Not Far From You…I half-traded/half-bought a starter culture of Armadillidium sp. “Montenegro” (this was before the name klugii was in common use), one of my all-time favorite isopod species. They thrived for a while, but then a mold outbreak in combination with poor feeding resulted in the loss of the entire colony. That is, except for one specimen. It has survived over a year now on it’s own in a tub, and to be completely frank I didn’t think much of it. However, I was discussing invertebrates with a friend when he mentioned he had a colony of A. klugii “Montenegro”. I mentioned I had one specimen left, and that if he liked I could trade/give it to him. He agreed, and soon I went digging through the tub to find the one specimen I had left. However, much to my surprise, I found two specimens! I have no idea how I missed the second one despite the multiple times when I looked through the enclosure. Anyway, I moved them to a smaller 3 ounce deli cup where I could keep an eye on them. I then sexed them a few days later, both turning out to be female, and again to my surprise I found that they both had the distinctive white mancae dots. Now I tore apart the tub they had been in, but no male isopod was to be found. There were a few old exoskeletons of specimens that had died, but I assumed they were from the previous colony crash. Maybe a male survived, impregnated the two females, and then died before I could find it?
However it happened, I’m glad there is still the possibility that these two specimens could restart the colony for me. The saying “Where there’s life there’s hope” holds very true in this instance.
Moving on, we shall leave the isopods in favor of another mystery…
While pulling some stow-away babies from my old Porcellio laevis “Dairy Cow” enclosure, I did a little digging around to see if I had missed any. I certainly hadn’t missed any isopods, but I had missed a millipede!
To lend context to this story, the enclosure I used to keep the P. laevis in had formerly been the enclosure for a 1:1 pair of Acladocricus sp. “Philippine Blue” millipedes. Unfortunately the female I believe died early on, and the male I transferred over to another enclosure. The enclosure sat empty of specimens for a while, although I retained the substrate, until I purchased the P. laevis. Needless to say they didn’t do well, so I moved them to a different enclosure. As stated above, I did find P. laevis babies however in the enclosure a few months later, leading to the discovery of the mystery millipede…
A true conundrum!
This ends our regularly scheduled “Isopods and Myriapods” segment. Now we turn to our spin-off program, “Insects Among Us”.
As some of you may recall, my Blaberus giganteus weren’t doing so hot (both figuratively and literally) last time we took a look at them. However, I am happy to announce that they have made a comeback! I was able to get some new specimens from a good friend to supplement the remaining three I had, and the night I introduced the new specimens one of those three, which had been looking plump for a while, decided to give birth to a bunch of nymphs!
I also acquired 10+ Gromphadorhina portentosa of various sizes from the same friend, as her colonies have increased in size immensely. They do seem to be hybrids of some sort, but either way I am very happy to add another roach species to the collection!
During a recent collecting trip I was able to locate three or so Jerusalem Crickets (Stenopelmatus sp.) within 5 feet of each other! I collected one and let the others remain. I have decided to trade it to a friend, but it is still stunning to observe while I have it. Large specimens of this species gain bright orange heads that an enthusiast can see from a mile away.
Now for the bad news. I was excited to share that I had been gifted by a friend a teeny-tiny Ctenidae sp. “Mamfe” spiderling, a species I really wanted. It was literally probably half the size of a small pinhead. It was doing well, eating like a champ, and then one day I found it motionless. It then rapidly desiccated into nothing. I didn’t do anything wrong that I can think of, as their care is pretty straight forward. Perhaps it was just one of those specimens that was meant to perish sooner rather than later…
And that will bring us to the end of this messy almost-January post. I have much more to update y’all on, but that’ll have to wait till the February post…
Merry Christmas everyone! Blessings on you and your household as we celebrate Christmas, however that may be, and as we move into the new year. May our collections continue to grow into what we want them to be; I know I’m looking forward to a 5th straight year of being in the hobby!
Hello fellow enthusiasts! It’s that kind of post again, with some new additions to the lineup. Unfortunately the gain in my collection is not without losses, which I will detail first.
The bad news: I lost my Brachypelma emilia (no, its not Tlitocatl) to what I believe was dehydration. It went too long without a watering during a time when I was exceedingly busy, and when I did overflow the water dish it actively drank quite a bit of water. The next day it was in the signature tarantula death curl :(. I am very frustrated, as I really like this species and to have it die in such a way is very saddening. Another victim of a lack of water was my Pseudoclamoris gigas. This was my third Tappie/Psuedoclamoris, and what I have found with these genera is that the moment the substrate drys out and/or they don’t have access to water, they keel over and die. The moral of the story is: water your slings! Don’t let them ever go without water for long stretches of time. I certainly learned that the hard way and plan on being much more vigilant in my care moving forward.
My brother’s Paravaejovis spinigerus MF finally died after close to three years in captivity. She gave birth to quite a few scorplings while in our care, and was a very hardy member of the collection.
In insect terms, my Blaberus giganteus have been slowly dying off one by one. I think it has something to do with old age, but I’m hoping the last few I have will leave me some babies before they too kick the bucket.
That’s the bad news, and now for some good news!
At the last Invertebrate Club of Southern California meeting, I was able to pick up 6 adult Centruroides exilicauda! Not only are these awesome orangish-tan scorpions, they are also awesome communal scorpions! They came with a ten gallon tank containing cholla wood and a variety of stones for them to dig scrapes under. This species doesn’t burrow per se, so I don’t have to worry about the stones shifting and crushing them as they form tunnels. There are both males and females in here, so I hope to soon see babies!
Also at the meeting I snagged my first Old World tarantula bigger than an inch…a, drumroll please…Chilobrachys sp. “Khiri Khan” (suspect female)!
A friend of mine who is new to the hobby received this as a freebie along with another NW he was buying. The enclosure, detailed below, is far from ideal, meaning the rehouse is gonna be a lot of fun, so I took it off his hands for one of my A. chalcodes slings. I also surprised him with my GBB (which was on his list) to get him going. The GBB I had received when I was new hobbyist at a huge mark down from a vendor who helped mentor me and start me down the invertebrate-keeping path. I decided this GBB was to be the gift that keeps on giving.
The last thing I got at the meeting was a variety of terrarium plants (including some awesome Pleurothallis sp. dwarf orchids!), which I will have to discuss further in another post. But just to sate your desire, here are some pictures!
Lastly, I ended up with 6+ or so odonata nymphs when my brother cleaned out his pond filter. I was totally shocked to find these things, as considering how big they are now, they must have floated into the filter as eggs or something, as the filter grille is far too small for them to get in and out of now. They reminded me of very overgrown Jerusalem Crickets when I first saw them, but since then I have been corrected by another friend of mine who is a master invertebrate identifier. Anywho I hope I can raise them to maturity to further reduce our local mosquito population, ha ha! Care tips are appreciated from any of you dragonfly experts!
Apologies for the poor photos, these things are so well camouflaged that it is hard to get a decent shot of them!
And that’ll do it for this post. Thanks for reading, I hope to have some really awesome content for a few future posts, so stay tuned. Catch ya next time!
Whoa, a post on the first of the month??? And there was a post in the month before?? Consider yourselves lucky…
This time I will be sharing some info and tips on how to protect your collection from earthquakes, and to a smaller extent wildfires and flash floods. This information was garnered from a brain-storming meeting at one of the Invertebrate Club of Southern California meetings. Since we are in an area that is expecting a “Big One” (we are actually very overdue for a large earthquake), we figured this would be a pertinent topic to discuss. However, since Southern California is not the only place that has earthquakes (I’m thinking of our fellow Indonesian enthusiasts), this info should be of use to all those who live in earthquake zones.
So how do we protect our collections? The first step is making sure your racks, bookcases, shelves, or whatever it is that your enclosures are on, do not fall down. To do this, you must have some form of strap that secures to the wall stud. I use these ones (https://amzn.to/2Zewvgx), although I’m sure similar products work just as well. Another thing that can be done is to place heavy enclosures, such as large glass Exo Terra or Zoo Med cages, down on the lower shelves of a rack. I’m sure we can all imagine what will happen if one of your racks falls down, especially if you have more potent/aggressive invertebrates.
With this done, you then need to make sure your containers do not slide off; this can be achieved by either placing enclosures on top of non-slip rack liners (https://amzn.to/30joqsf), or by using the metal racks with bars that also help prevent sliding. In the event that an enclosure does get flung off, it is very important to make sure you use containers with lids that close tight, otherwise you may end up with a Leiurus quinquestriatus or a Cyriopagopus lividum prowling around. Double containers may also work if you have large numbers of small slings in deli cups with lids that don’t always snap perfectly tight (taping the lids may also work). If you have hard plastic or glass cages (Critter Keepers, Sazon containers, glass terraria), it would best to place them lower down on the racks so that if they do fall off, there is a less chance of the plastic or glass cracking or shattering. It is naturally of utmost importance that you don’t have extra glass on the floor after a large earthquake, or venomous invertebrates running around; while they (the invertebrates) are more likely to run and hide, there is always a chance one may decide to stand its ground and fight. That is pretty much all you can do to prepare for an earthquake.
However, you must also make sure that after an earthquake hits, you have a plan in place to keep your collection alive during the recovery process. After the earthquake, it is possible, if not likely, that you won’t have running water, electricity, gas, etc. Therefore, it is important to make sure that you have the necessary means to keep your collection cool/warm, depending on the season. Most shelters will not accept pets outside of dogs, cats, horses, etc., so you cannot rely on them as places to where you can take your animals. If it is summer, you can keep your collection cool with the use of chemical cool packs, moving enclosures to a cooler room or in a lower area (as heat rises), or if you have regular winds, opening a window may be all that is needed to keep your collection cool. If it is winter, chemical heat packs and moving your enclosures to a warmer area are your best bet.
The problem of not having running water can be remedied by using the number of water filtration units that are available. Bottled water, and water from a pool if you have one can also be used if necessary. You should irregardless have an emergency store of water to supply you, your family, and all your animals in case of situations like this already. Many invertebrates can survive short periods in dry conditions, but if you have moisture dependent animals, it is important to have an emergency store of water to supply them for at least a week as well. Most invertebrates should be able to survive several weeks without food, but if you are worried about it, you can start a small colony of crickets, roaches, or mealworms to supply you in case of emergencies.
Your collection is an investment, especially if you have a large collection and/or expensive animals. While the local invertebrate market will likely be down for a long while after a big earthquake, you may be able to sell some specimens off to those outside of the affected area to help pay with repairs/necessities. It’s not likely, but it is still something that should be kept in mind.
I know that none of us would want to lose our collections, especially if it survived a large quake only to die in the chaos afterwards. Keep that investment alive, and you never know how it may pay itself back in the future.
Finally, other natural disasters; flash floods you usually don’t have to worry about, but if you think you may be in an area prone to flooding, move your invertebrates to a higher area in the house/room. Otherwise, there is not much that can be done in case of a flash flood.
For wildfires, you can only hope and pray that the fire does not take your house, because if it does, there is nothing you can do to save your collection. Most of the time you will have a small time frame to gather up valuables before having to evacuate, but I cannot stress this enough: make sure you and your family are safe first. If you have time, grab any irreplaceable items and vertebrate pets (as unlike most invertebrates, they will feel pain and suffer if left behind), such as picture albums, important documents, cash, the family dog, etc. Then if you have enough time, grab the invertebrates that you care about the most. It would be helpful to make a list of the specimens you wish to grab first beforehand, so that you are not stressing about which creature to take in the confusion of an evacuation. Naturally, if you have enough space and time, you can try and bring everything, but this may not always be an option.
And that is pretty much it! While it’s not suggested for you yo become an invertebrate doomsday prepper, with an underground bunker all ready to defend your valuable T. seladonia from anarchists, looters, and rouge USFWS agents, we do suggest that you at least take some precautions and have a plan in place for when an earthquake or other natural disaster comes. Just remember; you and your family’s and friend’s safety should take precedence over all your animals. There will always be another such-and-such invertebrate to replace one you lose, but human lives are irreplaceable.
