  1. When writing a post, you should see an option for dragging or choosing files to attach, like this -
  2. That's great news - looking forward to hearing how your rearing effort goes with these! In my area, we have Zopherus nodulosus haldemani, and it would be fantastic to be able to breed it. I've only ever encountered just a few examples of this species, but probably only because I've just found them incidentally, rather than going out looking for them intentionally -
  3. Yes - Chrysina tend to have a very long larval diapause after making their cells - well over half a year. Following this, the actual pre-pupal and pupal stages aren't particularly long. What species are you working with?
  4. ...cool jet black pathogenic roach! I think you may want to edit your post to say "parthenogenetic", instead of "pathogenic", as needless to say, the two words have very different meanings!
  5. The larvae with lumps on their backs are Scarabaeinae (dung beetle) larvae.
  6. You might check with Peter at bugsincyberspace.com - he often has some tityus larvae available around late Feb to late March.
  7. Eunica eurota - amazingly colored, small nymphalid butterfly from lower elevation rainforests in parts of South Amer. -
  8. Eushelfordia pica (Ecuador) is another very colorful tropical roach -
  9. As nymphs, those look a lot like trilobites, and also chitons. Here's another interesting one - Prosoplecta spp. (Southeast Asia), a roach that mimics a ladybird beetle (Coccinellidae) -
  10. MV bulbs (which were once commonly used in street lamps) aren't very easy to find anymore - for most purposes, they were phased out years ago. At least, in the US they were (partly because they contained mercury, and partly because they weren't very energy efficient compared to newer technology such as LED).
  11. A torchiere lamp won't produce the right wavelengths of light for collecting insects. At the very least, what you need is something like this - https://beetleforum.net/topic/4374-light-traps-help/?tab=comments#comment-24926 As for whether this could be run off of a car battery, I don't know, but certainly, such a fixture wouldn't require very much power. More power than an LED-based light, but still not too much (as compared to the requirements of an MV light, for example). You'd likely need a gasoline-powered generator to run an MV in the field, unless some high-power portable battery
  12. This might be the best snake mimic I've ever seen - it's the chrysalis of Dynastor darius (a close relative of the Owl and Morpho butterflies). The level of detail is amazing, right down to the false eyes with elliptical pupils -
  13. Weevils of the genus Pachyrhynchus have similar reflective structures - ...and also the genera Eupholus - ...and Lamprocyphus -
  14. Here's what the beetle's reflective nanostructures look like under magnification -
  15. Great photo sent to me today of Hoplia coerulea, the remarkable, iridescent blue "Monkey Beetle" from Southwest Europe, which is a close relative of the common June beetle - The males of this species are covered in photonic, reflective scales like those of Morpho butterflies. I've not seen any reports of this species having been bred in captivity, but certainly, it would be worthwhile to try! Like many other Melolonthinae, the larvae feed on certain kinds of live plant roots, and I suspect that the difficulties of providing this is why there doesn't appear to have been any captive br
