  1. @BeetleShelf Both Importation and exportation require permits, generally speaking. You will need a permit to have species exiting out from the U.S., and a separate permit to have species entering into the destination country. Also, even if it is legal to import alive animal in some countries, it may highly vary per species, per original location, how things are packaged, what comes along (soil, wood, whatever) with the target species, etc., etc... Things are quite complicate, and if you REALLY want to know for sure (so you can actually do it), you must contact USDA/FWS so you can get their names and/or their "official letters," so just in case you are in trouble you can provide the "evidence." USDA and FWS are two different agency, telling two different answers to a single question. One may say "yes," while the other one may say "no." If any of them said "no," then it is eventually "NO." FWS in DFW airport has different aspects from FWS in IAH airport. (FYI, agents in those two locations cannot even identify scarabs/birdwings.) So be sure to contact someone in USDA/FWS and get official letters provided to your name.
  2. Here I'm attaching a female pupa of Lucanus placidus I reared from an egg. I collected an adult female some time ago, and got some eggs from her.

    Sexing Gymnetis thula (caseyi)

    I don't think your picture is attached properly (check the size of file). Variation, or a phenotype, can be presented all kinds of animals and plants that reproduces by a copulation between a male and a female. Anything that goes through parthenogenesis or cloning won't show a difference from a parent to offsprings. Gymnetis thula has many different variations recorded in scientific publication: black with yellow markings, half and half of black and yellow, mostly yellow, entirely yellow, reddish brown with yellow, etc....

    Sexing Gymnetis thula (caseyi)

    Look at abdomen and see if there is any vertical groove on the middle of it for adults. If there is one, that is a male, and if not, female. In case of larvae, a small dot on abdomen near anus is present for males, while not for females. This, however, may be tricky (confusing) for small cetoniine species like Gymnetis.

    Geotrupes sp. in captivity?

    Good info from an expert + experienced person. I used my own for dung beetle trapping an year ago, and I was able to collect roughly over 200 Geotrupes blackburnii excrementi, as well as many different dung beetles and other Geotrupid species. I never tried to breed them though. Maybe I should try this year if I can acquire horse or cow manure. The reason not using human or dog must be the "smell." Since horse or cow only feed on plant materials, makes their feces not too smelly, but humans (or dogs) consume all kinds (meat+veggie), makes the feces smelly... I never really thought of using my own for breeding indoor, maybe in backyard, far from my house (building).. If the project fails to breed, then I was thinking about dumping the entire plastic container away...haha

    Pelidnota punctata

    the grapevines where I mostly collect these beetles were definitely different species from the harvested on in my backyard long time ago. But that didn't matter. I fed captured adults with the one at my backyard. So, probably, no, it does not matter.

    Pelidnota punctata

    One tip I can give you is to light up (if you are doing light trapping) at the forest where it actually has grapevines. There is no other reason why they are called as "Grapevine beetles." They love feeding on grapevine.

    Checking on my stag

    He is upside down to dry a ventral side of abdomen (belly). No worry, as long as he is inside the pupal cell, and not out in plain ground. If he is inside the pupal cell, he will be able to grab a wall and lift himself up. Try not to touch for next couple days. L. elaphus is not known to die out of shock like some exotic species, though it is best to keep it alone for a week or two since they emerged out of pupa.

    Pelidnota punctata

    Yes, these are F2 larvae. I collected a pair two years ago, and bred some larvae. They became adult beetles, and laid another batch of eggs. AND I actually collected a handful this year, so I added couple alive ones in the same container.. So I'm guessing they are all mixed up. I just looked up on BugGuide, and most recent records indicate P. punctata in New York are mostly active in July to August. In Louisiana, P. punctata are found in May to early July for the most, and still be found couple latter months.

    Geotrupes sp. in captivity?

    If what you are interested in is breeding (reproduction), then you will need to feed animal feces or your own works fine too. (I'm serious! ). If not, just keep them on substrate, spray water lightly, and nothing much can be done. They feed on animal feces, and I believe they lay eggs under piles of animal feces, as some other dung beetles do. (not a brood ball).
  12. Sharing detailed images of Strategus aloeus male pupa, before preservation. This specimen is collected as L3 larva in Texas on January this year.
  13. Yes, it seems it is far eastern side of Texas(still away from state border). I haven't collected it myself, but I have a colleague who has collected multiple males and females.
  14. what time of the year was it that you found dead males? Try go a month or two ahead of that time. In Texas and Louisiana, they seemed to be already out, and probably past the peak flight season.

    right place, right time

    Good images! I think I have always seen two rainbows together, and rarely ever seeing a single one.

    Last Night Collections

    sharing an image of collections from last night. Two male/female pairs of Dynastes tityus a lot of Strategus aloeus (some not shown in image). a single Phileurus truncatus (not shown in image). a single Pelidnota punctata (not shown in image). a lot of Cyclocephala lurida (not shown in image). with many more including Alaus myops, Prionus imbricollis, Tetracha virginica, Actias luna, Automeris io, Parastasia brevipes, Corydalus cornutus, etc.
  17. There is no way to calculate that. Or are you going to ask them? Just set them up. Let's say that female mated. But she doesn't like the set up you made in a tiny container (or even large container), and did not lay a single egg. Then you will probably assume the female DID NOT mated. Right? Since there is no egg found. Even if you saw the female mated with male, if you don't see a single egg from it. You will wonder what happened. You will wonder if the mating did not successfully happened. Or maybe the male is not a male (LOL). There is no such calculation to know whether the wild captured female is mated or not. If you want to rear it, just set them up.

    Last Night Collections

    I know, right?? This is my first time collecting this many Dynastes tityus in a single night. I've collected 1-3 specimens unto now, but I never collected FOUR in a single night. S. aloeus is pretty common here in a right time. This wasn't new record in quantity-wise for aloeus.
  19. I don't recall which specific research paper it was for the reclassification. Per the morphological difference between Allomyrina pfeifferi with dichotomus spp. group, dichotomus spp. are reclassified to Trypoxylus out of Allomyrina. A lot and many recent researches also (because of that) discusses it as T. dichotomus, instead of A. dichotoma.

    Attacus atlas

    Is that really Attacus atlas? Seems somewhat small... minor female?
  21. ?? Do you still have question? If you are keeping just an adult male, without breeding, not much things to worry about. Just feed him daily to once in two to three days with fresh beetle jellies or bananas, or any other fruits. After about two weeks you can handle them fine. He won't die out of stress unless you handle them several hours a day for everyday...
  22. If you are referring to dry floral foam that does not absorb water, yes, but you should either keep a cup of water inside the container or wrap the foam with wet paper towel for a good humidity. If you are referring to styro foam, then yes if you can carve it cleanly, and if the pupa can grab onto it to flip himself over. Anything works okay as long as the pupa can grab a sidewall to flip himself over.
  23. Firstly, Allomyrina dichotoma is no longer a valid name. It is now reclassified into Genus Trypoxylus, and the species name is dichtomus as the gender of genus has changed. Trypoxylus dichotomus is the valid name now. There is only one? species now in the Allomyrina, which is Allomyrina pfeifferi. The resting period for Trypoxylus dichotomus is a 4 to 6 weeks. You may have a pair set up together after 4 full weeks. After first picking up of eggs, you may separate male away from female, so female can focus on laying eggs, and not having another, unnecessary mating with male. Place many jellies (4 to 6) in a single time, and don't even attempt to open a container, if you would like to have many and many more eggs.

    What do you all make of this?

    Nope, it rarely ever comes out when it is alive, or freshly died. It is actually even difficult to cleanly (perfectly) dissect it out, unless you are an expert. Parameres is good key to identification, but endophalus is also a good key used in these days. Many new species description in these days discuss about endophalus as well. Rarely happen in scarabs, but often in Lucanidae.
