    Dear colleagues: My name is Daniel Patón and I am a professor of Ecology at the University of Extremadura (Spain). I teach two subjects Environmental Biotechnology and Experimental Techniques in Ecology. My specialization is the analysis of environmental data. I am interested in invertebrate composites such as isopods, worms, mealworms, soldier flies and of course cockroaches. We touch on these topics in my classes, but I have a lot to learn. I can bring knowledge of applied statistics and interdisciplinary training. 1. Do you currently raise any roaches? I currently care for three species of cockroaches: Eublaberus spp. "ivory", Aeluropoda insignis and Blaptica dubia. My main interest is the degradation of waste for composting. 2. If so, how many? I have several terrariums with hundreds of animals. I also have soldier flies (Hermetia illucens), mealworms (Tenebrio molitor) and two species of worms (Dendrobaena veneta and Eisenia fetida). I dedicate them to research and practical classes with my Environmental Biotechnology students. 3. Do you culture roaches as pets or feeders? I am mainly interested in degrading waste and generating compost 4. If feeders, what kinds? I'm interested in finding the species that degrades the most, doesn't require a lot of temperature, doesn't fly, is easy to handle and is not invasive. Some of these concepts are contradictory, but I'm still looking. So far Eublaberus and Aleuropoda are winning. 5. Are there any specific roach questions that you would like to ask the community? Yes, I would like to know which species would be suitable to set up a waste degradation centre in a place where the winter temperature does not usually go below 32 F (0ºC) zero degrees outside and reaches 113 F (45ºC) in summer. I suppose that in well-insulated buildings it would not be very expensive to heat. I am interested in the fact that the species is not invasive, although I understand that those that escape would die in winter. 6. How did you find our community? Asking experts like Kyle Kandilian, they told me about this excellent forum. It's not easy to find in searches, at least from Europe it didn't come up. I think it is a perfect forum, very well structured, clear and simple. Extremely useful Greetings **************************************************************************** Daniel Patón Numerical Ecology.

    True, but I think in terms of species that have seen long term success in captivity, we're catching up. Yeah there's certainly good people in both those hobbies, it's just hard to find them at times among the throngs of greedy vendors, stubborn groupies and jerks that "popularity" of a hobby and it's more prominent members can bring with it... 😅

    Thank you both for the feedback! I do not use organic and hadn't even thought of that so I will definitely make sure I peel things at the very least from now on. I don't think it's the heat lamp as I have been using the same ones since Sept. They are night vision ones so the light is low and the enclosure always stay at about 80 so I think that is ok for now, but thanks for that suggestion as well. They all came to me as full size adults from my science curriculum company - so I have no idea how old they actually were other than "adult." For some reason I thought the life span was longer - good to know. I need them to last me about another month fro my class and then I have a friend that is going to take them and raise them so I'm hoping to not lose any more. Thank you both again!

    @Hisserdude, I think it'll be a while before we get as big as Europe in terms of size. They've had the jump on us for decades and are still going full throttle, ha ha. A sure shame it is when that happens; if you keep your eyes open and your head on straight you'll find a lot of good people in both the isopod and tarantula sides of the hobby, but you are right, a lot of irresponsible sellers and hobbyists to waylay the new enthusiast and old hand alike. Thanks, Arthroverts

    I keep my non-climbing pie-dish beetles in a 2 gallon fish bowl and my E. arcanum in a slightly smaller bowl, both with no lids. They make great tabletop displays. i love being able to see them from all angles. I hadn't thought of putting isopods in one. I'll have to keep my eye open for more bowls!

    Hi we were just talking about the genus Gromphadorhina and Princisia with Orin on an other topic, and we were talking about their identification wich is difficult, and most of the time incertain. I think that a discussion about this would be really interesting on the forum, so that everyone can access the informations on this subject. Well, the discussion has started like this: me: "But beware, loads of hissers are actually hybrids or misindentified. I bought 3 different species last years, and give a male of each one to a friend of mine. He compared the genitalia with the schema of a scientific book and all the species were misidentified " Orin: "Gromphadorhina descriptions were based primarily on the horn structure of the male, I've seen some of the original descriptions. I'd love to see that schema of hisser genitalia in a scan. Original descriptions based on variable horn structure, pronotum shape and surface texture is why stocks I sent specimens of to a cockroach taxonomist identified as G. portentosa, G. oblongonota, and Princisia all interbreed readily in captivity. They probably are just geographic races and may not even qualify as different subspecies. It is not that people misidentify them, the original "Princisia" never existed and was simply a taxonomic error of someone trying to use a variable specific character as though it were a stable generic character (the notch in the pronotum) without checking to see the male genitalia were identical. However, this does not mean there are not a number of unique stocks that vary in appearance and specific husbandry." So, to continue this conversation, here is the scan: (sorry, he lend the book to someone and we can't remember wich species the genitalias refer to) It's from one of those books: • Herrewege C. van, 1973a – Contribution à l'étude des Blattaria de la faune malgache : I. Princisia, gen. nov., voisin de Gromphadorhina Brunner v. W., description d'une espèce nouvelle – Bulletin de la Société Linnéenne de Lyon. • Herrewege C. van, 1973b - Contribution à l'étude des Blattaria de la faune malgache : II. Description de huit espèces nouvelles appartenant aux genres Gromphadorhina Brunner v. W. et Elliptorhina gen. nov. – Bulletin de la Société Linnéenne de Lyon. According to the books, the pronotum isn't totally reliable: you can find different forms and sizes in a same population. The best way to identify them is the analysis of the genitalia, there are little differences... But they exists. In my opinion, in one hand, we should wait for the revision of those genus, and in a second hand, we should wait for the developement of genetics analysis and compare our hissers to the genetic code of wild hissers. This method is more and more used to identify diptera, we can hope to identify some hissers with this one day, and breed pure Gromphadorhina in captivity! You're probably right Orin, when you say Princisia is just a Gromphadorhina form. And I think that Gromphadorhina portentosa, Gromphadorhina grandidieri, Gromphadorhina oblongonata and Gromphadorhina picea are maybe four subspecies of a same specie, or maybe just geographic forms. There are already some forms known (some colours are related to particular area, other are just selection in bred).
