Mega Maritime Earwigs!

Last year I got a small group of Anisolabis maritima from Satchell Watts-Kerr, from Southern Mobile County, AL. These are some seriously large earwigs, females especially, rivaling Labidura riparia in length and surpassing them in mass. Adults are completely wingless, and males have very heavily curved forceps. This particular locality is fairly light colored, I've seen pictures of other localities with near black body coloration.

I have them set up in a minimally ventilated 5 gallon gasket bin with several inches of a coco fiber and sand mixture, kept moist. I am feeding them dog food, fish food pellets, and live micro-roaches (they seem to prefer the latter). I'm keeping them at around 75F°.

They've been breeding well, and I finally have enough F2 offspring to start offering these big 'wigs up! 😄

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

My New Prionotheca coronata Adults!

Well, I recently got my hands on a breeding group of 4 adult Prionotheca coronata, and I am SO stoked! These are the most impressive darkling beetles I have ever seen, not only are they HUGE and quite heavy, but their morphology is just so rad with their spikey elytra, and heavy pubescence! This is not my first time working with this species, but this IS my first time seeing adults in person! And hopefully with said adults I can produce a lot more larvae to work with than the few I had last time (and I'd like to think my skills in rearing psammophiles, including Pimeliinids has been honed in a lot better over the past several years).

I have the adults in a well ventilated bin with a couple inches of fine sand substrate, with a teeny bit of crushed leaf litter mixed in. I'm keeping a quarter of the sand moist, the rest dry, and am feeding them freshly dead roaches and dog food (they'll eat both, but do seem to prefer the dead roaches). I'm keeping them at around 80-85F°.

For a while I was getting worried I only had males, since I've seen mounting behavior several times, but no oviposition, but last week I found an egg on top of the substrate! Quite a large egg too, around 5 mms, and looks quite soft and fragile. So I very gently scooped it and some of the surrounding substrate into a separate deli cup, where it will hopefully incubate and hatch within a week or two.

So exciting, hopefully there will be many more eggs where this is from! In addition to being at risk from being trampled by adults, the larvae of this species are quite cannibalistic, so I'll be looking for and removing any and all eggs as I find them, to hatch and rear the larvae separately to improve survival rates.

Anyways, that does it for this post, I'll be sure to keep you updated on these amazing beetles! Thanks for reading, hope y'all enjoyed, and I'll catch you folks next time! 😉 

We Finally Have Aspiduchus in Culture!

This has been a long time coming, but we now have Aspiduchus, the sister genus to Hemiblabera, in captive culture! Not only that, but we have TWO species in culture! 😁 And boy they are huge compared to Hemiblabera, much larger than I was expecting personally! Cockroach hobbyists are truly eating good as of late. 😋

Firstly, I got a pair of Aspiduchus cf. borinquen "Manati, PR". This is a paler species, with very ovular wings on both sexes. This species is especially gangly with long legs compared to their bodies, on the males especially! The cave system these were collected from is apparently connected or likely connected to the cave system that the holotype was described from, so the ID on these is near certain based off the morphology and range.

I've got them housed in a moderately ventilated enclosure with a substrate of coco fiber, topped with a little eggcrate for them to climb on (they're mostly staying buried in the substrate). I'm keeping them moist, at around 75-80F°, and am feeding them food and fruits.

Male

Pair

These adults are a little battered, likely on account of being WC, however they seem quite healthy, and the female rather plump, so I'm hopeful they will breed and produce some babies here soon! From what I've been told they are rather easy to care for, basically just like Hemiblabera in terms of husbandry. 

---

Next up we have Aspiduchus cf. cavernicola "Rio Grande, PR". These were collected rather far from the holotype locality, so the ID is a bit more dubious, however cavernicola is the only other Aspiduchus described from PR, and they match the coloration and morphology of the A.cavernicola holotype well IMO. Still, the ID could be subject to change in the future if it turns out they represent a third, undescribed species from Puerto Rico.

These are much darker and less gangly than the cf. borinquen, with shorter, more circular wings. Size is about the same, with these cf. cavernicola being a bit more chunky.

I have them set up in a moderately ventilated enclosure, with a substrate of coco fiber, topped with a piece of eggcrate for climbing (again, these are mostly staying burrowed in the substrate). I'm keeping them humid, at around 75-80F°, and am feeding them dog food and fruits.

Unfortunately the female passed very shortly after arrival, however before doing so she gave birth to a healthy litter of 20 nymphs, so I can't really complain!

L1 nymphs

The nymphs look almost exactly like newborn Hemiblabera, super cute! Hopefully they grow easily enough, will be awesome to get a colony of these established! 😍

So cool to finally have this genus in culture, and they are even more impressive than I'd thought they would be!

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