  1. Both are actually Blaberus craniifer, but it is not kwnon if it's a selective breeding or a different local. Anyway, beware about hybrids, they exist and need to be avoided
  2. hi! Eurycotis floridiana young: male: female: bye!
  3. Hi! Eublaberus sp. Pantanal: male: female: young: bye!
  4. there are some here in Europe but I'm quiet sure it will fail once again...
  5. it's always a bit wet, and they have food... So we will see
  6. it would be nice that's true, but I only have a few females, so I don't want to isolate them and risk to lose the group with no reproductions :/
  7. Hi all! Well, last week, while feeding my roaches, I noticed this guy... And I say "oh! It probably just molted" and didn't annoy him. This week, I saw him again and think the same... But I had no new adults. So I decided to wait a whole night, so that a normal male would have taken his coulrs. But when I came back this morning, I noticed that this was his colour: this guy is nearly white! Check it out! with a normal male: normal male: brown antennae and legs: my "white guy": yellow antennae and very clear legs: bye!
  8. hi Eublaberus sp. Ivory: young: male: female: bye!
  9. hi! Elliptorhina chopardi: female: male: young: bye!
  10. and I heard Gromphadorhina picea is tought to be extinct in the wild...
  11. Hi Diploptera punctata young: male: female: bye!
  12. hi Deropeltis paulinoi young: male: female: bye!
  13. when you see the name of a location next to "sp.", that's the place where the first ones were caught, so yes, they are from Malaysia I think they are the same than the sp. gold
  14. I don't have the two forms, but that's maybe because I have just a few of them... I'll check that when the next generation will grow up
  15. I'm just starting the colony, but what other forms are you talking about? I'm curious about that
  16. hi Byrsotria rothi young male: female: bye!
  17. Alex, I think I haven't explained what I meant really well. Actually, I think that a big colony, when it's established, with thousands specimens, doesn't seem to suffer from inbreeding, and small groups, whan we always keep, for every generation, a same small amount of roaches, tend to stop reproducing. But you're totally right when you say that a colony can establish with a really few roaches to start it! Keith, in my view, inbreeding is not tho only, and probably not the main reason to get small roaches, gynandromorph and so on. It happen with loads of other insects, such as phasmids, wich may be parthenogenetic. Sometime something fail within the egg, something during maturation, and sometimes just uncommon genetics. All those kinds of weirds individuals can be found in nature, but they often die quickly, they haven't the good adaptations. But if the weird caracteristic is an advantage, then, it can reproduce, and yes, the babies can get that difference, that's just evolution. As you said, in captivity, roaches have no reason to die quickly, so the strange individuals live even if they should have been eaten in natura. Their caracteristic may be kept in colonies, due to their reproduction!
  18. Oryctes nasicornis nasicornis f. nasicornis, from Visé, Belgium
  19. hi we were talking about that a few weeks ago with a friend. We've noticed the same things in our colonies: a little colony tend to fail after a few generations, they stop breeding, and they need to get some new roaches to reproduce again. In a big colony, it seems that this problem doesn't exist. The colony survive for years and years, with no blood addition.
  20. Bleberus sp. Venezuela young: female, light pronotum female, dark pronotum male, dark pronotum male, light pronotum bye!
  21. Blaberidae sp. Kenya femelle: mâle: jeune: à bientôt!
