  1. As far as this species goes, I actually keep them in a fairly dry enclosure because their frass, dead individuals, etc. become moldy really easily. They've done great with just a tiny piece of apple thrown in for moisture, and I've gone weeks without misting. Their enclosure has decent ventilation in the form of pinprick holes.
  2. Hey guys! I don't get on here as often as I used to, but I was finally able to sex the pathogenetically-produced nymphs of my P. americana. They're all female! Unfortunately, I was only able to sex 8 out of 10 because I had placed the nymphs with their mom in a large-ish tub, and 2 went missing. I purchased more P. americana from Roman, but I didn't have other tubs laying around. Before adding the new roaches, I removed the parthogenetically-produced nymphs and placed them into a small deli cup, where they've been living for the past few months. I think I may have misidentified them and their mother. The roaches that Roman sent me look a bit different than the mother. While Roman's stock has very clear markings on the light-colored pronota, mine is larger and has a darker, less defined pronotum pattern. Anyway, although I know that it's far from proof that P. "americana" produces clonal young, I think it's a possibility that it does. I can't wait for these girls to mature to see if they'll lay viable ootheca. I've read that parthogenesis can only occur for a few generations in this species. I'd like to see if that's true for these guys.
  3. I've reccommended lesser mealworms before, but I'm starting to dislike them just a tiny bit. In some of my colonies, they can be controlled by placing shallow bowls of water to drown them. In some of my other colonies, I cannot do this because the roaches will drown as well. I'm not sure why certain roach species avoid drowning better than others, but when the lesser mealworm colonies get large, they become a nuisance because they eat food meant for the roaches. Also, they're hard to remove manually because they're small, fairly quick, and will go into the substrate.
  4. They practically look the same, except that sometimes in hatched ootheca, a brownish membrane that seperated the eggs is visible outside the opening. Also, if you gently squeeze the ootheca from its ends, a hatched ootheca will easily open. Squeezing very gently won't harm the developing eggs, but of course, be careful. With genera that lay larger ootheca( not Therea spp.), such as Blatta, Periplaneta, etc., the empty eggcase make a hollow sound when lightly tapped with a metal spoon or when being bumped on a hard surface. Once you know the sound, you can easily distinguish unhatched and hatched ootheca.
  5. While cannibalism is a possibility, I would imagine it does not happen often with Question Marks. Like hisserdude said, they're probably just hard to see because substrate clings onto them pretty well. Also, they'll often dig away from the area where they sense disturbances. Unless you threw them out while you were switching out their substrate, they climbed out because the enclosure walls got dirty, or they died and decomposed, I'm sure they're still in there.
  6. Thanks a lot for letting me know, Alan! Gotta go get me some.
  7. I'm very jealous. That's a beautiful tattoo! I've been dabbling with the idea of a Blatta orientalis in a style similar to the flea in Robert Hooke's famous Micrographia.
  8. Meanwhile my Panchlora colony is crashing! Some folks have all the luck
  9. Thank you Krissim Klaw. Unfortunately, this colony is fairly old with most if not all of my males having died. Maybe a few of the females are carrying ootheca, but I think I'll try again some other time if they aren't. I might also just try Panchlora nivea next time to see if I have better luck with them.
  10. Cool looking guys! Thanks for sharing pictures.
  11. Haha sorry, I could have and should have been more clear. Roman is correct in that I meant pinned dead insects. I was trying to say that since pinned insects, which obviously are dead and thus make no attempt to escape, are sometimes eaten by Dermestids, I would think that ecdysing roaches, which are immobilized, and ootheca, which are stationary, may be at risk of getting eaten. Unfortunately, I'm not too well-versed in the biology of Dermestids, so maybe someone with much more knowledge can chime in. Personally, I wouldn't worry about having them in my roach enclosures unless I've seen them munching away at my live roaches and their eggs. Lesser mealworms will hollow out several dead Blatta orientalis to its exoskeleton within a few hours, but I've never seen them going after ootheca or living roaches. Maybe it's the same with the Dermestids you have.
  12. I've seen cleaner crews being sold that included Dermestids, so maybe you just got yourself some free help with reducing the amount of dead roaches. However, I'm not sure if they'll eat ootheca and live roaches or not, and it might depend on the particular species of Dermestids since I've heard of them damaging and destroying pinned insect collections.
  13. When I first started keeping roaches, a lot of them, especially ones within the same genus, looked the same to me. Adults of some genera commonly available in the roach hobby such as Periplaneta, Pycnoscelus, Gyna, and Eublaberus are now easy for me to correctly ID to a species level most of the time. By looking at them over and over again, I quickly learned which characteristics belonged to which species. It's pretty easy once you know what to look for (coloration, pronotum pattern, size, habits, etc.). However, I still can't differentiate Blattella spp. (among many others) from one another
  14. Thanks for the reply, Doc. I'm wondering though, do they still need to have food constantly? I like to replace food daily because I don't like to give mold a chance to take hold.
  15. Hey guys, I'm having trouble getting my Opisthoplatia orientalis and Panchlora sp. "Giant" to reproduce. I've had adults for at least 4 months now. I keep them at around 75-85 Degrees, and they both have damp/moist substrate. I give them fruit and dog food daily, and they have lots of hides and a deep substrate. The females abort their ootheca very frequently, unfortunately. Does anyone have any suggestions? Or could someone share how they keep theirs? Thanks guys!
  16. Unfortunately, I don't have any experience with that species. However, I can say that most my roaches of a comparable size to that of Warty Glowspots mature to adults in about 7 months when kept at room temperature. When kept in temperatures of ~85 Degrees and fed exclusively cat food, I've had some females mature in 3.5 months, with males maturing even earlier. In my experience, some species don't seem to like being kept at constantly high temperatures, so if you increase their enclosure's temperature, check on them every now and then to make sure they're eating their food and are molting properly.
  17. Hmm, that's really interesting. Thank you for that piece of information. I'll keep it in mind in case of an extreme emergency
  18. Heartburn? Haha, do you have to eat them or?. I can't imagine crunching on one of these guys. Personally, I only use them alongside springtails and lesser mealworm beetle larvae to clean up dead roaches, eat spilled food, and keep mold off new wood thrown into moist enclosures. They can breed more prolifically than some of the roaches I keep so I have another spare tub that I throw excess isopods into. Sowbugs do better in enclosures with at least a little ventilation, in my experience. The pillbugs especially like their fresh air. They always slowly die on me when I don't give them ample breathing holes. I use sowbugs as "canaries" in some of my enclosures that lack ventilation by seeing how well they do. I know I need to open up my sealed roach enclosures more often when they become lethargic and stop breeding.
  19. Welcome aboard! I hope we can help you out with any questions you might have and that you'll share your experiences with us as well. Cornelius is a beautiful roach with beautiful coloring exemplary of how attractive pure Gromphadorhina portentosa can be. I'm glad you're enjoying him, and it sounds like you've given him a wonderful home. It's really fun to raise cockroaches as pets, and I'm willing to bet that Cornelius won't be your only roach for long. Check out the other hisser species if you're ever interested. And check out the other roach species too! They're a diverse bunch with plenty of species readily available, ranging from tiny to huge, from drab to colorful, etc. Have fun!
  20. Try it, although I have had major headaches with my Opisthoplatia orientalis and Panchlora sp "Giant" for a while, despite having tons of fruit, humidity, hides, and heat!. They just don't want to produce for me
  21. Thanks Doc and thanks Keith! So far, I have given them more substrate and more moisture in their enclosure. Unfortunately, they were still eating each other, although I saw they only picked off new mature males. I gave them eggs, and they devoured it, but they still seemed more interested in eating freshly molted males. I had to check out the enclosure every time I saw anything white to remove new matured males so they could harden their exoskeleton. It's a lot of work checking on them so often, so I finally just stopped checking. I don't know what made me do it, but I gave them more fruit than they could consume in a day, and they loved it! I'm not sure if it's the fruit's moisture or the sugar in them, but they are now no longer eating each other ,and I now have both males and females with almost perfect wings. I'm starting to think fruit might just be the answer to everything
  22. Thanks! I guess they just like being kept really crowded, although I am starting to separate male and female nymphs. I started off with a pair and a bunch of babies from Doc a few months ago. Some of the babies are now medium-sized nymphs and the female has given birth to two batches of young.
  23. I'm not sure if that means you don't want to see them, but here's my favorite ones anyway I apologize if they hurt to look at. Eublaberus posticus Oxyhaloa deusta Parcoblatta virginica Periplaneta fuliginosa Arenivaga sp. Obviously overcrowded Aeluropoda insignis
  24. I just took a bunch of pictures, but I'm not sure you're if interested in seeing low quality images of nearly identical-looking enclosures, especially since lots of my colonies are still fairly small.
  25. Yeah, they hatched out (: However, after checking the inside of the ootheca, I saw 2 did not hatch. They didn't even look like they developed at all.Altogether, there are 10 nymphs that did manage to hatch and look healthy as can be. Now, I need to see if they'll mature and I'll let you guys know if I get males. I'm majoring in biology, and that sounds spot on for humans and cockroaches. I was reading up on mole voles, where sex determination wasn't based on XX, XY, or XO sex chromosomes since both males and females are XO ,and the SRY gene has not been found in the autosomes of males. Since cockroach sex is determined by the XO system, I guess it's pretty different and less of a mystery, at least to the people who study that sort of thing. Would you happen to know if Surinames produce truly clonal young? I'm guessing that if they don't, then non-disjunction or deletion is what causes occasional males, although deletion would also make sense if their young are truly clones. Also thank you so much for the two terms. I'm going to have so much fun reading up on them.
