Green metallic beetle
Hi again, We have these beetles all around this year again. They run real fast and fly. Could not find in the beetle section, can you help? Thanks again,

Hi Art,
We have several images of Six Spotted Tiger Beetles, Cicindela sexguttata, that we have posted over the years. They are buried in our nine beetle pages. Using our search engine and the key words green metallic beetle should have taken you to the correct pages.

Am enclosing pic of beetle we can’t identify. Have searched books, charts, and net without success. Thanks

Hi Cosmo,
Finally that attachment worked. This is not a beetle. It is a True Bug, a Small Milkweed Bug, Lygaeus kalmii. They are immune to the toxins in milkweed, and are consquently toxic to predatory insects.

“Yellow Jacket” Moth
Here is a moth that looks just like a yellow jacket. It even has a fake yellow jacket mouth. Hope you enjoy!

Hi David,
We recently met a lepidopterist, Julian P. Donohue, who specializes in Wasp Moths. We will see if he can give us an exact species on this Wasp Moth. Here is what Julian wrote back: “Hi Daniel, The moth is indeed a wasp moth, family Sesiidae (formerly called Aegeriidae). All my references for this family are at the Museum, so I can’t begin to start putting a name on it. Where it was found would be a major help–there are many species that are very similar in appearance, but all don’t occur in the same places. The larvae of all are borers in roots and stems of various plants. The hostplant may be specific for a particular species, while other species feed as larvae on a variety of different plants. Some are severe pests of horticultural, ornamental, and agricultural crops. In the last two decades great strides have been made in studying the distribution and taxonomy of this family, using traps with synthetic pheromones as an attractant (most are dayfliers and very difficult to collect with a net–if you can even see them!). The pheromones were originally developed for use with sticky traps to detect the presence of pest species (e.g., peach tree borer), so growers would know when (and whether) to institute control measures. In haste, Julian “

Tawny Emperor – the end of the saga
Hi Lisa Anne and Daniel,
After a longer break, I want to keep my promise and send the last pictures of the Tawny Emperor (Asterocampa clyton) to you. They were a bit difficult to take, because the pharate pupal stage always appeared early in the morning. The pupa is a female, while the butterfly on the pictures is a male.

I want to add a little story here: In the beginning of June I went at night with a flashlight into the forest nearby my house and checked on approximately 10 trees for Asterocampa caterpillars. I found nearly 200 caterpillars in total of both species (celtis and clyton), sitting and eating on the underside of hackberry leafes. It was just amazing how many they were. If you try to find the sister species (Apatura iris or Apatura ilia) in Europe, you can consider yourself lucky to find one caterpillar in a year. OK, have a great time, and I will keep you updated when I breed new exciting species.
Best wishes,

Hi again Thomas,
Thank you so much for completing the saga of the Tawny Emperor. We eagerly await next spring to see what new species you will send our way.

I know you are busy, take a look if you can
Hi guys, attached is a photo of a caterpillar I’m trying to ID. I posted it on bug guide too. I also am sending over some other photos I took and posted on bug guide and you can use them onb your site too if you want to. Today I learned on your site the things I was calling silverfish were actually house centipedes and they eat other bugs in the house. Cool. I also read they can produce a painful bite. Not cool. Generally speaking, I’m not a bug killer (we have a “backyard safari” bug vacuum) and all tresspassers are released. Since I’m a high school teacher I always make it a point to set an example when we have a bug intruder in our classroom and make sure it is tossed out the window. Is there a way to post pics to the site like bug guide or do people just mail them to you?

Dear Unknown Teacher,
Since we are control freaks about the aesthetics of our site, we do not allow visitors to post. Imagine what we might find? We do not want Jenna to appear on our homepage one day. This is a Mourning Cloak Caterpillar.
