    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).
  7. Sharing detailed images of Strategus aloeus male pupa, before preservation. This specimen is collected as L3 larva in Texas on January this year.
  8. 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.
  9. 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.
  11. 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.

    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.
  14. 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.
