  1. Friends, please tell us under what conditions do you incubate ootheca of your Polyphaga (P. saussurei, P. aegyptiaca)? Interested in all information - duration, humidity, temperature, etc.
  2. Yes, she was already at the adult stage. Will hope!
  3. Yes, of course. It is hoped that this female mated with a male in the desert. It would be excellent
  4. I collect materials on the authors of Gromphadorhini tribe taxa and cannot find information on Christian Van Herrewege. It is known that he died in 2002, in Lyon, but there is no other information. To know at least the date of birth of this entomologist. Still, this is a key figure in the study of the tribe, but he made an invaluable contribution! Maybe someone knows the date of birth?
  5. This is a female of the Polyphaga saussurei (Dohrn, 1888). I caught her during my expedition to the Kyzylkum desert, in southern Kazakhstan. They live in burrows of monitor lizards and other desert animals. That was at the end of August. Yesterday I noticed her ooteca, it is very pleasing, but there is a risk that nothing will be born from it.
  6. I regularly observed this in all species of this genus that I had, including Panesthia a. angustipennis. Indeed, this is a demonstration of the sexual behavior of males and it is typical for the genus Panesthia, and it is possible that for the entire subfamily.
  7. I have been given several individuals of Ergaula, but they are unmarked. Do you think this is E. capucina or E. pilosa? The male size is about 30 mm (or less). And another question that worries me is: can these two species interbreed?
  8. Yes, indeed, the signs of Gromphadorhina oblongonota are completely invisible here. Apparently this is G. portentosa at the base of the hybrid.
  9. Yes, unfortunately, the problem of hybridization is very acute. It is necessary to strictly label cultures and by all means prevent hybridization.
  10. Of all the Blattodea, I am most interested in the species of the Gromphadorhini tribe (probably noticeable in my nickname ). Naturally, I strive to collect all kinds of this group of cockroaches. In any case, those that are in laboratory culture. For a long time I’ve been looking for Leozehntnera maxima (van Herrewege, 1973), but unfortunately for some reason they are nowhere to be found. I wonder if someone in the laboratory culture has them and can they be bought?
  11. No, apparently not that. Beetles are daytime, and cockroaches are nocturnal; they just don't need such protection. In addition, this happens only in males, females are always clean and shiny. I assume that this is due precisely to the libido of males. There is an assumption that this substance has an attractive smell for females. It would be very good to examine the chemical composition of this substance, as well as the abdominal pleura for any glands there. Only who would do this?
