    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) -
  4. 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).
  8. 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.

    Attacus atlas

    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

    Attacus atlas

    Argema mittrei (Madagascar Comet Moth) - that's another amazing giant saturniid with long tails -

    Buprestis rufipes and Stenelytrana gigas (video)

    Many thanks for that info - M. magnificus is definitely on my "top 10" list of beetle species to eventually go looking for in AZ! Also on the list, are the large click beetles Chalcolepidius apacheanus, Chalcolepidius webbi and Alaus zunianus, as well as some of the less often collected species of Cetoniinae, such as Hologymnetis argenteola.

    Attacus atlas

    Very impressive - one of my favorite moths! I'll always remember the first time I ever saw this species live, at a butterfly house. Hoping to also eventually see a live Coscinocera hercules; another giant, that combines the size of Attacus atlas with the long hindwing tails of Actias luna: Male - Female -

    Mydas fly (Mydas clavatus)

    Speaking of flies, the giant Timber Flies (family Pantophthalmidae) from S. Amer. are also quite impressive. Apart from being some of the largest flies in the world, their larvae are very strange - they are wood borers in live trees, and look very different from typical fly larvae; morphologically they actually have more in common with the larvae of longhorn beetles. The adult flies are short-lived and don't feed at all - I'm sure I'll have more to show, as the season goes on - very wet, humid summer this year, with even more insects than usual.
  14. A large Mydas Fly (Mydas clavatus) that I found today. I see these flies every summer, usually around wood piles. The larvae live in rotting wood or rich organic soil, where they are predatory on scarab beetle larvae. The adults (which mimic spider wasps such as Anoplius spp.) have an iridescent blue-black sheen to the wings, and flash bright orange abdominal markings when startled. This specimen is rather large for a US species, but some South American forms, such as Gauromydas heros, are even larger, and are among the biggest flies in the world.
