Hawai'ian cockroach stowaway

The skulls are legal, yes. They're feral hogs, which aren't protected at all. Our suitcases got inspected twice on the way back! First by US agriculture, checking for plant materials (the vast majority are illegal to move between Hawaii and the mainland), and once by the airline checking for bombs, and neither of them did anything about the skulls. We didn't hide them or anything, just put them in paper bags and stuck 'em in. Meat might be harder to import, but the only concern with skulls is if it's something endangered.

It would definitely have been illegal to bring these guys in, just like that. I might have been able to get a permit with some calling around, though, since these aren't a crop or human danger. But it's not illegal to accidentally bring something over, nor is it illegal to own, say, an accidentally imported spider. 

I definitely should have checked better to see what was in the skulls (Hawaii has centipedes! yikes), but I was overheated at the time and not really thinking anything other than "sweet, skulls". The real worry with things from Hawaii is accidentally bringing a true farm pest over that doesn't live in the continental US yet, which you find in plants, farms, and related areas, and this was an area without any farming. Well- farm pests and rat lungworm, but the lungworm is on snails, not hogs.

They seem to be doing fairly well so far. A smoky brown roach got in there somehow, and I'm leaving it in there as kind of a canary/comparison. It's not bothering them or anything, I find them in the same hiding spots when I check. 

Also, I don't know if it's the Madeiras or the smoky brown, but something has been dragging the food bits under a leaf to eat. 

I see them out at night sometimes. I don't think I have to worry about them escaping- they don't seem to like the petroleum jelly. They'll go up to it and inspect it, but most of the time don't even touch it with a foot. Maybe they don't like the smell very much. One is out now, I can see by my reading light, and it's just kind of wandering across the glass.

I moved a box in my closet and found another one. I also transferred them into a new enclosure. I found 5 total while transferring them, but I wasn't checking, just moving the substrate over in big heaping handfuls, so I imagine the rest of 'em are in there somewhere. 

There's a couple that are a good inch long at this point, and I didn't note any smell while transferring them, which I'm glad for. I also noticed that they seem more likely to run down into the substrate now when disturbed, instead of up and around like they did before, so I'm guessing it's because they're used to their environment and think it's safe. 

I gave them a cow vertebra to explore, found in the same place as them. I'm tempted to give them the skull they were found in, but I'd never get 'em out of there again! Too many cavities.

Wow, resilient little buggers eh? 😂 Glad the little colony appears to be doing well still, fingers crossed they continue to grow and then breed for you! :D

 
@Betta132 any updates? i see you havent been on in awhile but heres a shot in the dark! this was such an amazing read! if they take off/have taken off with the bow-chicka-wow-wow and are rare in the hobby im sure you could definitely make more than a few pretty pennies!

 
I do have an update: species confirmed. I think.

I know I have this one in there, alive and kicking. I haven't seen any of the others in awhile, though. This one was actually found loose! I think it escaped early on, before I had them in proper containment, and it seems to have been pretty happy to grow and develop outside the enclosure. Probably in my houseplants. I did NOT sex it while I had it out, since I know these have a stink defense and I didn't want to risk it doing that. 

I'm actually going to be making a post elsewhere of rehoming these. I have some chronic fatigue issues that are flaring up, so I'm trying to downsize my critter collection pretty far. I know I have this one in there, and I'd ship the whole enclosure's worth of dirt and leaves in case there's more in there. I can't make any guarantees about there being more than one. But if someone would like these, they're up for grabs. Just on the condition that, if there's multiple and they breed, I can call 'dibs' on a culture of them in a couple years. 

They really are a handsome roach, but I'm trying to downsize my bugs. Down to isopods (since they eat the dirt) and the domino roaches that mostly just eat leaves. 

Does anyone know where universities get these guys? I've found several academic papers from people at universities studying these, and they seem to be well-established as a live specimen to use for various things. They must come from somewhere. Maybe somebody could find the supplier and buy some for the hobby?

Definitely R.maderae, congrats! 😁 Thankfully it turns out there are one or two cultures of this species still in the US, so they're not extinct yet and will likely become more commonly available in the near future, (whether the interest in buying them will be there or not, time will tell). 

Sorry to hear about your chronic fatigue, I hope you're still able to partake in the hobby, just with fewer species. Wish I had the funds to nab this group, however I'd likely only keep them for a generation or two anyways, to help make sure enough people have them established in the US, then move on, so someone else would probably be a better candidate for you. Regardless of who gets them, hopefully they'll breed well for that person and we see this species established in the US hobby again. :)

Ah, good- it's a relief to know I'm not literally the only person with any in this country! I was actually trying to look into where laboratories get theirs, to see if any suppliers are legally able to sell to a private collector. I think I'd like to keep a culture of these guys when I get myself better medicated, they're sort of handsome. Something about the lines and the soft coloration. I bet a bustling culture of these would be really nice to look at.

I do still have domino roaches, since they're super easy to keep happy. I accidentally left the culture in a cabinet for two months last year, and they'd all grown when I remembered them. Leaves, dirt, and a little moisture does it for them. I feed them dog food and fruit when I remember, but they really are happy with just the hardwood leaves- growing, maturing, breeding, all that good stuff. And my condition (basically low blood pressure) is manageable, but I'm still trying to wrangle the damn thing, and don't want to neglect live animals while I do.

Yeah so they should be fine in the US hobby now, fingers crossed, BTW this line should probably be labeled differently, like R.maderae "Hawaii" or something, (even more precise locality information would be good), so people know there are two distinct lines in culture, so be sure to tell that to whoever ends up getting yours! :D

Glad to hear your condition isn't too difficult to manage, hope you can get it all figured out soon and return to keeping more inverts in no time! :)

 
Awesome to hear they were in fact R. maderae ! Not so good to hear you've been having Chronic fatigue though, hopefully it improves in the near future. I enjoy keeping this genus. I love watching them feed and interact with each other. I have the "Gold" color form of these guys.
