More Italian Bugs, & Other Odd Additions!

I have finally established a colony of what I believe to be Chaetophiloscia elongata from Trastevere, Rome, Italy. The founding stock was a mere two females, and this species seems to have relatively small broods. However they're finally in the dozens now, and I just moved them to a larger enclosure, which will hopefully help bump their numbers. 😄

I've got them in a moderately ventilated container with a thin layer of coco fiber substrate, topped with leaf litter and bark. I'm keeping them humid, at around 75-80F°, and am offering dog food as the supplemental diet.









Here's hoping they keep breeding and doing well for me, so I can eventually make them available!

Earlier this year I got some Arcitalitrus sylvaticus, AKA "Lawn Shrimp" from Smugbug. These terrestrial amphipods are widespread in the coastal US states, and prefer moist conditions, but not soaking wet/stagnant. They can jump quite well, kinda like springtails, so care must be taken that their enclosure is tall enough that they can't leap out while you are doing maintenance on them. They spend much of their time underground and so prefer an organically rich substrate that they can feed from, though they will scavenge more protein rich foods from the surface of the substrate as well.

I keep mine in a minimally ventilated container with a couple inches of coco fiber, sphagnum moss, and sawdust mixed together with leaf litter. I'll top off the leaf litter and sometimes add more sawdust as well as they consume it all. I'm keeping them moist, at around 75F°, and offer dog food and fish food as the supplemental diet.





A very interesting, obscure invertebrate in culture, would love to get more terrestrial amphipod species in the future! And perhaps easier to care for freshwater species as well... 👀

This summer I acquired two Blaps cf. mucronata localities, a single female from the Colosseum in Rome, and a group of adults from near the Pyramid of Caius Cestius, Rome. These are sometimes called "Graveyard Beetles", because of their affinity to living in old, less kempt graveyards and similar environments amongst urban areas, cellars of old houses, parks, etc.. 

Now I got larvae from both groups, however while they've proven easy to rear to a mature size, the pupae and teneral adults seem very picky about humidity levels, so I've had issues getting any to adulthood. I've reared one adult successfully of the Pyramid locality, I'm concerned I may lose the Colosseum locality though...

I've got both localities set up in well ventilated containers with an inch or so of coco fiber substrate mixed with a tiny bit of sand. I keep them on a 50/50 humidity gradient, at around 75-80F°, and feed them dog food as the staple diet.
I've been isolating larvae to minimally ventilated deli cups with moist substrate, as I do Eleodes, however I'm having to workshop the ventilation and moisture levels now to try and increase pupal survival... Hopefully I can figure that out relatively quickly. I'm going to aim for lower moisture and higher ventilation going forward.




Here's hoping I can figure out how to rear these more consistently, Blaps have been a dream of mine to work with and I'd really like to succeed with them!

I got some Armadillidium gestroi "Zinger" earlier this year, also from Smugbug, and they bred and established themselves for me very quickly (as is standard for this hardy species). I really love the contrast on this morph, which features white spots on their backs instead of the normal yellow.

I have mine set up in a moderately ventilated container with a thin layer of coco fiber substrate, topped with bark and leaf litter. I'm keeping them at around 80-85F°, humid, and am offering them dog food as the staple diet.



Definitely a neat morph of a nice and hardy species, great for beginners and experienced isopod enthusiasts alike.

Lastly, earlier this year I got a group of Armadillidium vulgare from Pisa, Province of Pisa, Italy. These are maybe the only strain of wild type, Old World vulgare in culture here in the states, and I gotta say they are pretty neat for wild types! Rather dark, sparsely mottled with yellow spots, and overall a bit smaller than most US stocks I have.

I have them in a well ventilated enclosure with a thin layer of coco fiber substrate, topped in bark, sphagnum moss and leaf litter. I'm keeping them on a 50/50 humidity gradient, at around 75F°, and am offering dog food as the supplemental diet.






They've been breeding and slowly growing in numbers, and are overdue for a rehousing to a larger bin here soon to really bump those numbers up. 😅

Anyways, that does it for this post! Thanks for reading, hope everyone enjoyed, and I'll see you all next time! 😉

New Isopods, Wide Horn Hissers, & Domino Roaches!

Alan Jeon graciously sent me a culture of Ctenorillo sp. "Boqueron, Puerto Rico" a few months back, and they're doing great and breeding quite well already! These are a small but heavily textured species, relatively recently introduced to the hobby.

I'm keeping them in a moderately ventilated container with a thin layer of coconut fiber and sphagnum moss substrate, topped with crushed leaf litter and bark. I'm keeping them pretty humid, and at around 75-80F°. I'm feeding them dog food and fish food as their supplemental diet.





A cute species with unique morphology, I'm really happy to have some in my collection now!

I recently got some Gromphadorhina oblongonota from Russ Gurely, which he says came from the Philadelphia Zoo. He never mixed these with any other bloodlines, and so far they look quite pure to me, which is great since pure oblongonota are becoming harder and harder to find here in the states. The last group I had came from Roachcrossing, but I traded them back to him since his colony crashed (and unfortunately he was not able to save them even after getting those individuals back from me). So I've been on the lookout for this species for a bit, and I believe I've found good stock of them now. 😄

I have them set up in a well ventilated 5 gallon gasket bin with a thin layer of coco fiber substrate, topped with bark and eggcrates. I'm keeping two thirds of the enclosure humid, the rest dry, and have them at around 80-85F°. I'm feeding them dog food and fruits as the staple diet.

Here are some pictures of a nice, large male (not a *true* major though IMO):






Really hoping these breed well for me, I have several females that look ready to burst at the seams! 🙏 Would be nice to spread the love and make some pure oblongonota available myself! I also low-key wanna try some creative hybrid projects with these... 👀 Imagine what oblongonota to Aeluropoda would look like, the morphology (especially the pronotum shape of major males) couldn't be more different... 🤔

I got some Ignamba sp. "Nigeria" from Smugbug earlier this year, and they have proven to be quite the hardy and prolific species! 

I have mine in a well ventilated enclosure, with an inch or so of coco fiber substrate topped with leaf litter and bark. I'm keeping them on a 50/50 humidity gradient, and at around 75-80F°. I'm feeding them dog food as their supplemental diet.






These are a nice little oddball species, one of very few African native isopods established in the US hobby!

Lastly, after getting hybrid stock last year and having to destroy that culture after realizing that they were compromised, I have received pure Therea bernhardti stock from Zail Zavala (who got his from Roachcrossing, who got his from the EU hobby over a decade ago).

This stock is pure and seems to only throw out individuals with black hindwings. Supposedly there were two stocks of "bernhardti" in the EU hobby, those with black hindwings, and those with orange hindwings, and some keepers apparently mixed those stocks together... it's quite possible those were two different species, or at least two distinct localities of bernhardti (apparently both have very short hind wings, so I'm betting on the latter TBH). 
However, this stock is old, has not been mixed since they came to the US from Europe, and only throws out individuals with black, short hind wings. So they should be pure bernhardti, which were originally described from hobby stock with short black hind wings, with the locality info of "Tiruvannamalai, India". I can't speak for other stocks of this species available in Europe and the US, but at least this line appears to not have been contaminated by other bloodlines/species.









I've got several of them maturing ATM, so I should start getting lots of babies in a matter of months, and will hopefully have them available by Spring. 😄 So happy to now have pure stock of all 5 cultured Therea spp... I'll have to talk about the two spp. that are actually new to US culture here in a future post. 😜 

Anyways, that does it for this post, thanks for reading, hope everyone enjoyed, and I'll see y'all next time! 😉

Alan's Arenivaga IDs!

Alan Jeon the GOAT has taken it upon himself to dissect and key out a good portion of our cultured Arenivaga species, and while several tentative IDs we had were confirmed, some were corrected instead, and some have been shown to likely be undescribed!

Here's a list of the species he dissected, labeled first as what we have been calling them in the hobby, with their correct ID following:

  • Arenivaga cf. apacha "Cave Creek Canyon" = Arenivaga apacha
  • Arenivaga sp. "DOT Rest Area, Amado - Dark" = Arenivaga apacha
  • Arenivaga sp. "Miller Canyon" = Arenivaga apacha
  • Arenivaga sp. "The Thing" = Arenivaga apacha
  • Arenivaga tonkawa "Ft. Davis" = Arenivaga erratica
  • Arenivaga sp. "Animas" = Arenivaga erratica
  • Arenivaga sp. "Lakeside" = Arenivaga estelleae
  • Arenivaga cf. genitalis "Butcher Jones Recreation Area" = Arenivaga genitalis
  • Arenivaga sp. "Sahuarita - Small/Dark" = Arenivaga genitalis
  • Arenivaga cf. hopkinsorum "Pena Blanca" = Arenivaga hopkinsorum
  • Arenivaga cf. tenax "Soccoro" = Arenivaga tenax
  • Arenivaga cf. erratica "DOT Rest Area, Amado" = Arenivaga tonkawa
  • Arenivaga cf. erratica "Sahuarita - Light" = Arenivaga tonkawa
  • Arenivaga cf. tonkawa "Ector County" = Arenivaga tonkawa
  • Arenivaga sp. "Hesperia" = Likely Undescribed
  • Arenivaga sp. "Madera" = Likely Undescribed
  • Arenivaga sp. "Mescalero Dunes" = Likely Undescribed

What a revelation! So far it's looking like we have no shortage of apacha and tonkawa localities, evidently those two are some of the most widespread (or at least easy to find) Arenivaga! 😄
One important thing to note is that there is a high potential for there to be cryptic, undescribed species in this genus that key out as one species or another currently, but may get split based on other morphological and/or genetic features in the future. So some of these IDs may change again over the years, and you may see some of those "apacha" and "tonkawa" populations split into several species in the future.
It's also neat that we got some almost certainly undescribed species in culture, hopefully descriptions will follow eventually and we can put names to those as well!

In any case, huge thanks to Alan for going through and identifying these all, now we finally have a better idea of what's what with our hobby Arenivaga! 😁

Sand Roaches, Isopod Updates & Discoids!

I have successfully isolated pure cultures of both species in the Arenivaga spp. "Sahuarita, AZ" stock that Kyle from Roachcrossing sent me. The smaller of the two stocks appears to be A.genitalis, whereas the larger ones I'll be talking about in this post should be A.erratica

These cf. erratica are quite similar to the "DOT Rest Area" erratica I have (which were also found sympatrically with a smaller Arenivaga species, namely A.apacha), though they seem to have less dark spotting on them.

Female

Male

Pair

A hardy and easy to breed species, definitely something I could recommend to a beginner for their first Arenivaga.

Several month back I recieved a small group of Arenivaga cf. investigata from Borrego Springs, CA. This strain looks different than the cf. investigata I already have from the Imperial Dunes, namely the nymphs are a darker color, and the pronotum markings on the adult males seems to be quite a bit darker. Females look rather similar, though a bit less rotund than the Imperial Dunes stock as well.

I have them set up in a well ventilated enclosure with an inch or so of sand substrate, topped with crushed leaf litter. I am keeping a third of the substrate moist, the rest dry, and am keeping them at around 80-85F°. I'm feeding them dog food as the staple diet.

Male





Female


Here's hoping they'll breed for me as well as the Imperial Dunes stock does! 🙏

My Armadillo officinalis "OG Hobby Stock" colony is doing phenomenal, and while topping their leaf litter off, I got some pictures of 'em.




This colony has been throwing out Orange individuals (you can see one in that last pic), which I have successfully isolating a true breeding colony of as well! Need to show those off at some point for sure...

It took them a while, but my Armadillidae sp. "Miyako, Japan" colony is finally popping off! They seem to like consistently humid conditions, and lots of leaf litter. When I kept them on a humidity gradient they barely did anything, but once I started keeping the entire enclosure humid they really started doing well.





These are also throwing out solid orange individuals, which I should probably try and isolate... yet another project for future me to work on. 😅

Finally, I acquired a colony last year of Blaberus discoidalis "Banana Bay, FL" from Brandon Maines. This stock was collected by Brandon himself back in 2018, and thus technically probably has different genetics than Roachcrossing's "Banana Bay" stock (which was collected circa 2015).
So for all those nuts out there who insist on adding "new blood" to their colonies (an entirely unnecessary and potentially harmful endeavor that can lead to accidental hybridization), this specific stock has value as a pure line you can outcross your Roachcrossing "Banana Bay" stock to without compromising your colony purity. And you can actually potentially increase genetic diversity in your colony in doing so (which isn't possible for most hobby roach lines that came from a single import, and are thus all very related anyways).

Anyways I have my colony in a well ventilated enclosure with a couple inches of a coco fiber and coco coir chunk substrate mix, topped with eggcrates. I'm keeping a quarter of the substrate moist, the rest dry, and am keeping them at around 80-85F° (previously I had them closer to room temps, and they were hardly breeding at all, bumping the temps up REALLY helped with productivity). I'm feeding them dog food and fruits as the staple diet.



It took them a while but they are finally starting to pop off for me, they seem to like drier and warmer conditions than I'd initially thought.

Anyways, that does it for this post, thanks for reading, hope everyone enjoyed, and I'll see you all next time! 😉
