  1. Ok, thanks for the advice! I got lots of isopods, now I just need to get some springtails!

    No problem! Kyle actually got his F. candida stock from me, so, if you purchase from him, you will have the same strain that I use. :)

    You could also just collect some springtails locally though. In most regions, you can find multiple species in a single small sample of soil, although not all of them will be easy to culture.

  2. I simply use vaseline and Sterilite tubs for most hissers. The only exception is Elliptorhina javanica. Somehow the small nymphs can get past the barrier. None of the other hissers I've kept can do this.

    I also use sealed containers for N. cinerea, E. floridana, and Gyna species. I don't use the gasket containers. I just get buckets and lids from Home Depot and add aluminum mesh for airflow. These are a much cheaper alternative.

    That's a good idea. I'll have to get some buckets from Home Depot. Out of curiosity, what do you use for housing "display" colonies (if you happen to keep those)?

  3. I don't know what region C. magnifica is native to, nor do I know anything of its biology. However, I can say that it is illegal to import any insect species into the United States without a permit. The USDA inspects shipments from other countries and I know a couple of people who were fined for importing exotic insects (not realizing it was illegal). Another important factor to consider is the extreme rarity (and endangered status) of many insect species. In this case, it is simply unethical, as well as difficult, to collect individuals from the wild.

    There is also, of course, the fact that an immense number of species are nearly impossible to raise or breed in a captive setting. For example, the vast majority of ant species will not mate in captivity (due to inbreeding avoidance, need for certain environmental stimuli, etc.) and most termites (especially the Termitidae) require very specific environmental conditions that are challenging or impossible to replicate in a captive setting. Indeed, this is no doubt the case for most insect species, and is probably true for many roach groups as well.

  4. I believe they are just regular carpenter ants... They suck because they come in packs of hundreds. I can always try and get photos for you but they may suck :P

    The large numbers don't sound like Camponotus to me, but that is certainly possible. Camponotus spp. tend to keep the majority of their colony's population outside and then build small satellite nests indoors.

    Photos (even blurry ones) would probably be enough for at least a genus-level ID.

  5. Currently, feeders go to Platymeris biguttata assassin bugs, leopard geckoes, and several ant colonies (Tetramorium caespitum, Myrmica cf. americana, Pheidole ceres, Tapinoma sessile). We are also anticipating the acquisition of a couple poison dart frogs. :)

  6. Earlier today, I took a tour of the local university insect zoo. I donated a few insect species and ended up with some assassin bug nymphs in return. I assume that they are Platymeris biguttatus, given the coloration.

    Does anyone have experience with these? Are they difficult to maintain?

    Thanks!

  7. If you let them establish for like a year in heat and suddenly take them off heat they would do fine for a primary feeder. I have mine right by my house heating stuff and they breed like crazy. Being constantly at 78-90 with the heat from the baseboards makes life a whole lot easier.

    They breed like weed in high temperature, I keep mine in 80F; 70F may be too low for fast breeding. I won't be surprise if they can cause allergy problem in some individuals; actually I've developed light allergy against roaches already but I don't know which species is the main reason since I have ~40 species lol. But I would suggest always be careful when dealing with large cockroach colony which has a lot of smell, fecal and debris.

    Thanks for the help! I appreciate it. :)

    I'm just looking for a species that would make for an effective and productive composting organism, without the need for spending money on extra heat.

  8. I have a few questions regarding Nauephoeta cinerea (lobster roaches) that I was hoping someone could answer.

    • Given their high reproductive rate and generalist habits, I thought they might be useful in a composting system. Thoughts?
    • Will they continue to breed well at room temperature (~70 F)?
    • Has anyone ended up with allergy problems from this species?

    Thanks in advance!

  9. Something else interesting to mention, while we're on this subject, is that obligately parthenogenetic species usually do not last very long on an evolutionary time scale. The "Red Queen" hypothesis suggests that this is mainly because asexual organisms (at least, multicellular ones) cannot adapt quickly enough to changing pathogens/parasites. There are other explanations, but I think that this one makes the most sense.

    Of course, there are exceptions. Darwinulid ostracods, bdelloid rotifers, and oribatid mites have all reproduced exclusively through parthenogenesis for tens of millions of years.

    Anyway, this subject is particularly intriguing to me, as you can probably tell. :)

  10. There are actually two major forms of parthenogenesis.

    • "Apomictic parthenogenesis" is essentially cloning. Unless a mutation occurs, all offspring are identical to their mother.
    • "Automictic parthenogensis," on the other hand, is not true cloning. Often, this happens when two haploid egg cells combine to form a viable embryo. It is basically self-fertilization (extreme inbreeding), although no sperm cells are involved. In many species (usually those that also use sexual reproduction), offspring produced in this way are much weaker.

    I'm not sure which type parthenogenetic cockroaches would use, but I hope that helps a bit. It might be worth mentioning that some termite and preying mantis species (both close relatives of cockroaches) are known to use the second - automictic parthenogenesis.

  11. Oh I keep them seperate in simple tubs at room temp (I know slower production but its what I can do right now) about 70 F. egg crates, no real substrate. I feed daily scraps of fruit and veg my dragon doesn't eat. They have a third of an orange for moisture. Same set up my B.Dubia have. I wouldn't put them together though. I wanna be able to track how my colonies are doing. They are both pets and feeders. I just got back into the Dubia, I have 10 of each kind of roach.

    I think that this species will need a substrate to carry out its life cycle properly. Someone please correct me if I am wrong though.
