Hawai'ian cockroach stowaway

What do they live on in the wild? The vertical hiding spots makes me think they'd probably like to hide under loose bark on trees. Or, I guess, in the sinus cavities of animal skulls. 

The apple has dried out, and they've had a go at it. At this point, I seriously think they just didn't know what to do with the juicy stuff. They're from a very dry island- a mountain range on the adjacent island blocks storms, so the climate on the island they came from is scrubby. It almost looks like savannah from overhead. There definitely wasn't any fruit growing anywhere near where I found them. They might not have had fruit in generations, depending on how far they tend to roam.

One is hiding right under the top layer of the dirt. At least, I assume. I sprayed in a little water and a roach-sized patch of dirt moved around slightly like something was under it. 

Are the adults reasonably bold? I'm hoping I'll be able to find that one I put in my tesselata enclosure, once it hits adulthood. It being 17% of my stock and all. 

Does anyone know if these have a relatively even male/female ratio? I'm hoping they're not like Therea

Yeah, they probably can be found under loose bark on dead trees and such, as well as objects lying on the ground. Not a lot of research has been done into their preffered wild microhabitats TBH... 

Interesting, well I'm glad they like the dry stuff then! :D

Weird, I've seen a couple of non-burrowing Blaberid nymphs do that before, they'll hide under loose substrate if frightened... 

Probably, I mean they can climb glass as adults, so you might just find it climbing the walls of the enclosure one day! 😂 If the enclosure isn't too big you should be able to find it pretty easy I think, as they aren't burrowers, so it'll be on a hide somewhere... 

Pretty sure it'll be a similar ratio to other Blaberids, however you could still get unlucky and have a unisex group, you never know!

Good news: I found another baby in the house. Bad news: it was dead behind the laundry bin (across the hall from the suitcases), probably killed by exposure to soap scum. It must have left the suitcase or skull at some point and gone in there. 

I'm inclined to try and set up some kind of trap, just on the slim chance that there are live ones loose somewhere. It is, however, entirely possible that roach has been there for awhile. I'm thinking of just a crumpled, lightly moistened paper towel and some sort of food, set under a slightly elevated plate, to see what turns up. That would probably lure in a roach, right? 

The ones I have, as far as I can tell, seem to be doing well. I'm trying not to bother them any. They're still occasionally hiding under a very thin layer of dirt, but definitely like harder hides.

I've only successfully trapped hissers so I don't know if this will work, but I've set out favorite foods (i.e. fruit) on top of egg crates and caught escapees. They come for the food and stay for the egg crates, so I think you're onto something with the paper towels. Looking forward to see if you can get enough to start a colony!

Ah, good news! I found a live one!

Bad photo because he was lively, but definitely the same kind, and not one I had already. He went downstairs from where my suitcase is, the cats hassled him, and then he ran into the bathroom, so hopefully soap scum or whatnot doesn't get the better of him. This brings my total to 6 in the dedicated enclosure, and 1 in my tesselata enclosure if I can find that one. If I can just get an adult m/f pair to mature at the same time and breed, I should be set! 

 

Definitely gonna set up some traps around the house. I'm also gonna remember to check skulls that I collect really, really well for things, I forgot to do that this time. These guys, I don't mind, but I could end up bringing a centipede or something into my house if I'm not careful.

I'm so excited by this! I hope you get some adult pairs, too. What a crazy backstory for a new species in the hobby. Crossing my fingers for you.😉

Yeah, I really hope I have at least 1 pair in here. I figure all I really need is a male and female that mature at the same time and breed, and then their offspring can breed with any not involved in the pair. I mean, people get six roaches as a small starter colony, and that's what we're doing here! 

It's too bad I can't sex them at this point. I wish I could put a little urinal in there and count how many of em use it. That's a reliable way to sex roaches, right? Miniature urinals? 

How big are the adults in this species? I figure when the nymphs get to near adult size, they should hopefully be sexable. Though I don't know if I want to handle them to sex, stink defense and whatnot.

That's great, fingers crossed you get a pair or two, I mean you've got 7 now, you'd have to be quite unlucky to end up with a unisex group! 😂

Well not really a new species, rather an old one that people in the US kinda stopped breeding, still an amazing find though for sure, (and a great story as well! 😄).

Adults are 45-50 mm in length, so kinda sizeable. And you can always put them in a clear ziploc baggie and turn them upside-down to sex them. :)
