  1. Not about beetles, but earlier this year, I got this extremely comprehensive book from Japan about the natural history of Birdwing butterflies, by Hirotaka Matsuka - http://kawamo.co.jp/roppon-ashi/sub177e.htm I've never before seen such a complete treatment of the subject - the amount of work involved in producing it must have been incredible. It even includes photos of the caterpillars and chrysalises.
  2. My last correspondence with Bill Wallin was 7 years ago (June 2012). Surely though, he was not the only one to have ever produced tityus X granti hybrids? In any case, please always be careful to keep hybrids separated from pure species cultures.

    Figeater Beetles - General Questions

    I had great results with rearing C. nitida last year. My solution was to place a layer of lightly compressed clayey/sandy soil (thickness approx. 2") at the bottom of the rearing containers once the larvae were fully mature and nearing time to build cocoons. The larvae dug down into this layer and made quite solid cocoons in it. Survival rate was 100%. I kept each larva in a 16 oz. deli cup, but so long as they aren't too crowded, I think that rearing to maturity in a group should be ok. I'd think that 25 would be ok pupating in something the size of a 10 gal. tank.
  5. Here's an interesting species that I've only ever found maybe 3 times - the Giant Diving Beetle (Cybister sp.) -

    Geotrupes sp. in captivity?

    Oxysternon is another beautifully colored genus of Neotropical dung beetles. They're closely related to Phanaeus. Some photos -

    Geotrupes sp. in captivity?

    Not a geotrupid, but I've always thought it might be quite worthwhile to try breeding the giant metallic blue phanaeine Coprophanaeus (=Megaphanaeus) lancifer from South America, if an opportunity ever turned up for some hobbyist to do so. It's one of the largest dung beetles (the size of a golf ball) found in the Americas, and interestingly, instead of feeding on dung like most other Phanaeini, they're carrion eaters. They're incredibly strong for their size, and I've heard that a pair of these beetles can actually bury a pig carcass, over a period of several days! Another unusual characteristic is that both sexes have horns.

    Geotrupes sp. in captivity?

    I don't know much about Geotrupidae, but I've occasionally found blue, gold or black species of Geotrupes in my local area. As with other beetle families, there are some considerably larger, even more impressive ones in the tropics, such as Enoplotrupes sharpi (Thailand) -
  9. Where does L. capreolus occur in TX? In the state's far east, close to LA, perhaps?

    right place, right time

    Yes, I'm sure that would be a lot less of a mess than the lemon meringue pies that usually come flying out of them! I get the impression that a large percentage of rainbows are in fact double, but that one is always much fainter than the other, and not as noticeable.

    right place, right time

    Took this photo in my backyard, right after a thunderstorm yesterday afternoon. The rainbow only lasted just a few minutes, but I think it was the most vivid one I've ever seen; I just happened to be in the right place, at the right time.

    Attacus atlas

    Was that specimen raised from a larva in the US, or did it simply emerge from an imported cocoon? Just out of curiosity - if reared in the US, do you know what food plant was used? I've heard that in captivity, this species has been kept on Sweetgum (Liquidambar styraciflua), as well as Eucalyptus gunnii, Pistacia spp., Rhus spp., Mimosa spp., and even Toxicodendron pubescens (Poison Oak).
  13. It has been my experience that, statistically, the probability of any wild-caught dynastine scarab having already mated by the time it is collected is quite high. Once they emerge, the females are quick to locate a mate, since they only have a rather limited time in which to do this, and then find suitable sites in which to lay their eggs. This is especially true of temperate species such as D. tityus, in which the life cycle is strongly tied to the seasons.

    Oh - I should have explained: I don't actually have these moths - those are just photos that I found through Google Images! - https://www.google.co.uk/search?biw=1024&bih=663&tbm=isch&sa=1&ei=Xx8aXYLVEsfWtQa_soiYBw&q=Coscinocera+hercules&oq=Coscinocera+hercules&gs_l=img.3..0.1762.2158..2461...0.0.. https://www.google.co.uk/search?q=Argema+mittrei&source=lnms&tbm=isch&sa=X&ved=0ahUKEwie07i1_ZPjAhW6AZ0JHa8ODd0Q_AUIECgB&biw=1024&bih=663
