    Beetle larvae

    True. For many insects though, being out in the open and exposed to the risk of predators (or unfavorable weather conditions) is unavoidable. They survive mainly through their ability to breed in large numbers, ensuring that at least some will manage to live to produce the next generation.

    Beetle larvae

    Some species of cetoniine scarab larvae will emerge from the soil in response to rain and crawl around on the surface, if the ground becomes too wet. It might have been looking for some drier soil, or, it was possibly fully grown and seeking an area where the soil was of a more suitable composition (more sandy / clay) to build its cocoon underground.

    Beetle larvae

    Definitely the larva of a Flower Scarab (subfamily Cetoniinae), but as for what species it is, I have no idea.

    Found beetle larvae - rhino beetle?

    Possibly the larvae of a species of Euphoria (such as E. inda).

    Favorite animal and why?

    "The Common Insects of North America"? That's a classic, and one that I frequently looked at too. In years past, I'm sure that every public library of any size in the US likely had a copy.
  6. 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.
  7. 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.

    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.

    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.
  11. 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) -
  15. 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.

    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).
  18. 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..0.69.137.2......0....1..gws-wiz-img.Ednf3qILVWU 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 -
  21. Video of a couple of interesting beetles found in the backyard this afternoon - a Jewel Beetle (Buprestis rufipes) and a giant lepturine longhorn (Stenelytrana gigas). Stenelytrana mimics the Tarantula Hawk Wasp (Pepsis spp.), which is said to have one of the most painful stings of any insect (second only to species such as Paraponera clavata, Synoeca cyanea and Polistes carnifex).

    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 -
  24. Short video of a Bumelia longhorn (Plinthocoelium suaveolens), found today. Both sexes are iridescent metallic green, with red and black legs. Males (like this one) have extremely long antennae. Although their host tree is common in my area, I've only ever found a few of these beetles (possibly, because they only tend to emerge once the heat and humidity are so stifling that wandering around looking for them is very rough going! It's a much-sought species by cerambycid collectors, and I didn't even know they existed in my area until I intentionally starting looking for them around 5 years ago. I've heard that they'll definitely come to bait traps, but I've only ever had any real success finding them sitting on the trunks of their host tree (Sideroxylon lanuginosum). Like many other longhorns however, they will come to sap flows on some other tree species, such as Red Oak (Quercus buckleyi).
