  1. 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) -
  5. Where does L. capreolus occur in TX? In the state's far east, close to LA, perhaps?

    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.

    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).
  9. 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 -
  12. 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 -
  15. 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).
  16. 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.

    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.

    Bumelia longhorn (Plinthocoelium suaveolens) (video)

    I keep them as specimens. The larvae can only live in the root crowns of live Bumelia trees, so captive breeding would be problematic. P. suaveolens has a rather wide geographic range - it's been found all the way from Delaware to Arizona. Here's a page with more info about the species - https://beetlesinthebush.com/2009/09/28/north-americas-most-beautiful-longhorned-beetle/ Also - http://texasento.net/suaveolens.htm Some great close-up photos - https://live.staticflickr.com/6070/6119335428_57a265c3f1_b.jpg https://live.staticflickr.com/6088/6118789963_16769e3f0b_b.jpg https://farm7.staticflickr.com/6082/6119336024_e44da3c713_b.jpg

    Buprestis rufipes and Stenelytrana gigas (video)

    Depending on what's available in your area, you might try offering it leaves of Acer (Maple), Fagus (Beech), Nyssa sylvatica (Blackgum), Quercus (Oak), or Ulmus (Elm). Those have been reported as host trees of the adults.

    What do you all make of this?

    How long did he live after becoming active? Is this Lucanus elaphus? It's been my experience that this species only lives for around 10 weeks at most after becoming active. It seems that that their days as an adult are rather limited after they've mated - shorter than is the case with many other Lucanidae, and various Dynastinae.

    What do you all make of this?

    Better not to pull on it in any way - that could cause internal damage. If it's what I suspect it is, it will probably fall out on its own, eventually.
  23. Goliathus

    What do you all make of this?

    Most likely, a spermatophore filament. Had the beetle recently mated?

    Buprestis rufipes and Stenelytrana gigas (video)

    The B. rufipes I just found randomly on the side of a building. The S. gigas was at a sap flow on a Red Oak (which is where I nearly always find this species). Late yesterday, I also found a Purpuricenus linsleyi on the same tree. I had never seen this species before, and it's the first purplescent longhorn I've ever collected. That's how it is with insects - whenever you think you've seen everything there is to see in your local area, something new turns up! Hoping to find a Megapurpuricenus magnificus someday, in AZ. I've heard that you have to be in just the right place, at just the right time, to find them. I don't think I know even one collector who has a specimen, despite the fact that when they do emerge, it can be in rather large numbers. They're probably not very easily collected, unless attracting them with bait, but that's true of many beetle species.
