  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.

    Incubation ootheca of Polyphaga

    Thanks a lot!
  3. I have been engaged in Gromphadorhini species for quite some time and throughout the whole time, and I observe in all cultures without exception a whitish coating on the tergites of the male abdomen. I noticed that it appears only in mature males, who are very active and exhibit pronounced sexual behavior. Males that do not exhibit this behavior have no plaque. What do you think it could be?

    Polyphaga saussurei

    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.

    Polyphaga saussurei

    Thanks friends!
  6. 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?

    Ergaula: capucina or pilosa?

    Thanks friends!

    Polyphaga saussurei

    Yes, she was already at the adult stage. Will hope!

    Polyphaga saussurei

    Yes, of course. It is hoped that this female mated with a male in the desert. It would be excellent
  10. 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?

    Noisy Panesthia angustipennis angustipennis

    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.

    Gromphadorhina oblongonota

    Yes, indeed, the signs of Gromphadorhina oblongonota are completely invisible here. Apparently this is G. portentosa at the base of the hybrid.

    Gromphadorhina oblongonota

    Yes, unfortunately, the problem of hybridization is very acute. It is necessary to strictly label cultures and by all means prevent hybridization.

    What an ugly population you have!

    Leozehntnera maxima

    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?

    White bloom on males of the tribe Gromphadorhini

    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?

    Hello from Russia!

    Hello dear like-minded people! I am very glad that there are so many of us — Blattodea lovers around the world. Thank you very much to the forum administration for hosting me here! I have been doing Blattodea for over 20 years. His main interests are the tribe Gromphadorhini, the family Corydiidae, and the subfamily Panesthiinae. In general, I love everyone Blattodea sensu lato

    Hello from Russia!

    "Tiger" are very close to Princisia, they have very similar pronotums. If you look at the photographs of the typical material Princisia vanwaerebeki — holotype and paratype, then we can conclude that Princisia sp. 'Black and White' and P. sp. 'Tricolor', which is often sold as Gromphadorhina grandidieri, is simply a variation of P. vanwaerebeki, apparently arising in the culture. From the black (typical) Gromphadorhina grandidieri, they noticeably differ in the form of pronotum.

    Hello from Russia!

    I have G. grandidieri from Jörg Bernhardt, they currently go with him like G. portentosa 'Black', and before, they sold him like G. grandidieri. Now the validity of the taxon is being called into question and many believe that it is just a black morph of G. portentosa. However, the description of the lectotype and paralectotype states that G. rgandidieri are completely black cockroaches. The genitals of males G. grandidieri, G. oblongonota, G. picea, G. portentosa and Princisia vanwaerebeki are identical, I prepared the preparations and compared them. It may well be that these are generally all subspecies of the same species.
