  1. That's impressive. How does this species avoid overcrowding? Do they just begin to reduce offspring number after they reach a certain population density?
  2. Globular springtails have a fascinating courtship ritual as well. Here is a link to the best YouTube video that I could find that documents this (watch from 4:06 and 7:32). BBC has a much higher quality video of this behavior, but I can't find it online. It is in the first episode of the "Life in the Undergrowth" series and can be found on iTunes.
  3. I remember hearing from a few people in the past that they are very difficult to culture. They are certainly a fascinating group though!
  4. I will have to try this out at the Botanical Garden. They have a few interesting tropical ants (Tapinoma melanocephalum and Cardiocondyla sp.) living among the plants. I've noticed queens on several occasions but have not had a way to collect them quickly.
  5. Interesting. How well does it work for you? Does it ever result in deaths for smaller arthropods?
  6. May I ask what your reason is for ordering these? I can understand why someone would want to culture Periplaneta spp., but Blattella germanica seem too risky to bother with.
  7. I keep them in a small dark container with a moist coconut fiber substrate. I offer them cuttlebone and moistened dog food, both of which they consume surprisingly quickly. At the moment, the temperature ranges from 68 to 72 degrees F. Edit: Having said that, I think they prefer higher temperatures (~80 F). In the winter, their reproduction and growth have slowed drastically.
  8. By the way, are there any roach species that will breed prolifically at room temperature (~68-72 F)? I have heard that Hemiblabera spp. will not slow down significantly at these temps, but my understanding is that they reproduce at low rates anyway.
  9. Thanks! I'm fairly certain that it is Zoo Med, although the cable is definitely not that long.
  10. Sounds good. I have a heating cable lying around somewhere, so I will have to try it out this weekend.
  11. Thanks! Is it necessary to tape them to the underside of the enclosure (e.g. with electrical tape)?
  12. Interesting. What temperature is your house?
  13. I'll have to try that. Do you just place the container on top of a coil of heating cable?
  14. I am just interested in learning what each member here uses as heating methods for their captive cultures. I don't have many roach species at this point, so I have only ever used heating pads. Thanks!
  15. You should try not to let them affect your thinking and self-esteem. Insects are the animals that run the world. Their huge significance is already beginning to be more widely appreciated and those who view them with this sort of ignorance are just lagging behind. The first advice that comes to mind is to take their actions in a good-natured way and they will eventually get bored with trying to bother you. Having said that, the bit about the dumped coffee sounds more like genuine bullying and perhaps should be treated as such. Just some motivational history... The prominent evolutionary biologist, E. O. Wilson, had a bucket of ice water dumped on his head during a speech because his ideas on sociobiology were too new for people. Now, he is greatly respected and admired by scientists of all disciplines. Here is a link to a documentary about this: https://www.youtube....h?v=wKbj3ZDmvdU Good luck! I hope they realize the ridiculousness of their actions soon.
  16. I think that is unlikely, given that these snails appear to be tropical. Also, they don't seem to take an interest in live vegetation. I agree that it would be a good thing to mention to them though.
  17. Nice! Have you had success with breeding the B. fumigata in that small container, or is that just a temporary enclosure?
  18. That would be a very risky thing to do, considering that the USDA does inspect a portion of packages coming in from other countries, and consequences can be severe. However, I agree with you that many exotic species probably arrive that way.
  19. The US has strict regulations about importing animals, so it is difficult to bring in species from other countries. It seems that many captive species end up filtering through the cracks anyway though. Perhaps they are brought by researchers.
  20. I have no idea. I originally collected them from a tropical greenhouse, so I wouldn't be surprised if they do well in the same conditions as P. nivea. They seem to prefer moistened dog food as a food source. Also, a constant supply of calcium is necessary for their survival.
  21. Yes. At the moment, they are living on a substrate of coconut fiber.
  22. I might try that at some point. I have added a couple of snail species to my aquariums in the past, but I can never get them to survive for very long.
  23. I may offer some here after I begin splitting them up into more cultures, so I will let you know.
