  1. There's not a single observation that prove Lucihormetica actually glow. http://s3.amazonaws.com/academia.edu.documents/33860605/Greven_Zwanzig_Courtship_Mating_and_Organisation_of_the_Pronotum_in_the_Glowspot_Cockroach_Lucihormetica_verrucosa_Entomo_2.pdf?AWSAccessKeyId=AKIAJ56TQJRTWSMTNPEA&Expires=1466796404&Signature=CPCL4X7xoWujWRGUosBi3DliU5k%3D&response-content-disposition=inline%3B%20filename%3DCourtship_Mating_and_Organisation_of_the.pdf Above is a thorough study of the mating behavior and morphology of L. verrucosa. Based on dissections of live specimens, no evidence sho
  2. I've developed allergic reaction to roaches (I think the main reason is I have to work in a German cockroach rearing lab facility weekly). Now I've stopped handling any large sized cockroach like hissers or Blaberus due to the same symptom you've got, otherwise it doesn't affect my hobby.
  3. Yep they're short lived, and have a long nymphal stage like Therea
  4. Adults are gone, and I see small nymphs digging around. Will wait till they're bigger to make a better count. Apparently they are periodical, just like Therea.
  5. nice design, you'll need a much larger container for adults though
  6. I have some G. capucina, it's easy to keep them alive but I haven't got them breeding yet. At least there's two people here have pretty healthy producing colonies so I don't worry about it disappearing from the hobby
  7. 60F is not cold enough to knock them down. They are not going to do well in low temperature but you need it to be pretty cold to actually kill them directly. There should be something else wrong, post some pics will do more help
  8. In lab we fed peanut butter to German and American cockroach, definitely not gonna kill them at all.
  9. Just make dry food pellet (dog food for example) and drinking water always available, you don't need to do extra work until the food/water's running out. For soil/leaf litter set up mold can be a problem, but hissers can be kept bone dry without substrate. In that case there'll be hardly any mold occur on food.
  10. At least AU insect farm have them labeled as $85 for 3 nymphs here. http://www.insectfarm.com.au/pets.php Well, I understand if people think that's very expensive for cockroaches
  11. It also depends on local availability. In Australia those are sold in much lower price; the price in Europe is higher, but still not as expensive as they're in the US.
  12. Also check with the seller's minimal order policy. The price of hissers are just slightly higher than feeder roaches so online sellers may not gonna do a 3 bucks deal.
  13. Agree with Salmonsaladsandwich that drooling cockroaches are stressed or defensive. I feel the same way with mine. Grasshoppers/katydids/crickets/caterpillars etc. do the same thing when stressed.
  14. Eupolyphaga sinensis for medical use are mostly captive-bred. Mass breeding of this species is easy and cheap so there's no reason for wild collecting. Personally I'm not a follower of traditional Asian med; but just like other markets what they're looking for is profit. If captive breeding makes profits people will do it.
  15. So they have a Korean name? Wow that's wonderful, considering 1. they don't distribute in Korea and 2. they are not common in international pet or specimen market. Do you know where their Korean name comes from? well the color varies on different light condition... some times they looks almost black lol but yes they're mostly blue with some green and purple, depends on how you look at it. They are not called "Taiwanese flower roach" in Taiwan though, it's always hard when comes to translation but the name's like "banded red&dark blue cockroach". This species is also endemic to China a
  16. I've been keeping them since last year, those are quite slow growers but hopefully will start producing ooths for me soon How about banded purple roach? Pretty straightforward
  17. It's pretty much impossible to separate all the nymphs and substrate, I would just take some substrate with enough nymphs which keep the colony going, and sell/give away/freeze the rest substrate.
  18. Eggs and new hatchlings; the newborns are tiny as dirt. Nymphs, resembling to Therea but smaller Adult male Seems there're less females and they don't hang out as much as males. The males are super active, especially during the day since it's a diurnal cockroach species. Despite their small size it took them almost a year to develop to adults; still need to see if they're prolific breeders or not.
  19. Actually I keep them much drier than many people do. Medium moistened substrate+thick layer of leaf litter+minimal ventilation, that's what my set up looks like. Leaf litter is their major diet, and they got all the water they need from substrate. I toss in little amount of dog food occasionally for treat. As a result the whole bin is clean and mold-free, and the colony is growing like weed; I started with 2 dozens and now I even cannot tell how many thousands of roaches in there. A lot of dead adults is common for this species if you've got a big colony.
  20. Are you using any flashes? I love to use flash light for better pictures, but my gecko hate it lol...
  21. Also on wide horn juveniles you can see a unique black-with-whitespot coloration. The maximum size wide horn can reach is more than regular hissers, but it doesn't mean that every wide horn hisser is a giant.
  22. I'm not saying "there can't be", just a very small chance there're true predacious roach. The whole Blattodea group are scavengers and rely heavily on gut symbionts to break down cellulose, which lead to the evolution of wood-eating and eusocial eventually. If there's a predacious species out there it means that it will have to evolve carnivorous adaptions totally independently; so there's a small chance you'll see true carnivorous roach. But I'll be excited if anyone find one
  23. Yes two of the close relatives of cockroach are mantis and termite; but they're not equally related. Mantodea is a sister group of Blattodea, ie they share the same ancestor. While termites are true Blattodean; they're called termite not eusocial cockroach merely because when people name them they've got no idea that these are the same group of animals. That is why you see a lot of subsocial and wood boring cockroach, while there's no true predacious cockroach. Cockroaches will intake animal protein source occasionally, as well as termites (for termite, in most cases it's their nestmates). B

    Hello

    Welcome! To have fun here you don't need to be a native English speaker, neither am I We all know that the best language in the world is hissing =D
  25. You live in a roach heaven! So jealous I suggest this Flickr page to you http://flickrhivemind.net/Tags/blattodea/Interesting Many of those most stunning roach images are from Costa Rica, wish you can find them too! The first one looks like Epilampra hualpensis or similar species.
