Can you help identify?
Hi there, I have recently moved from the UK to central Boston and have found several of these flying insects in my city center apartment. Their bodies are generally 0.5 to 0.75 inches long. I am unsure if they are attracted by light or not. Thanks in advance

Hi Mike,
We wrote to Eric Eaton to properly identify your beetle. He wrote back: “Ok, the beetle is the “Wharf Borer,” Nacerdes melanura. It is in the
family Oedemeridae, the False Blister Beetles.” Adults are usually found on flowers or foilage near water and the larvae live in decaying wood. It is common in woodsheds, cellars and lumberyards. Originally European, it has been spread around the world due to commerce.

tomato leaf eating bug
I hate this thing! Tons of them are eating my tomato plants!

Hi Robert,
The closest I can get for you is it is one of the Chrysomelidae, or Leaf Beetles. It looks to be a close relative of the Cucumber Beetles.

Moths
I took some digital photos of a moth in Prince George, British Columbia, Canada. I haven’t been able to find a picture on the internet that can tell me which moth it is. The blue beam in the picture is 4″ high by 1-5/8″ wide. That makes the moth about 2-1/4″ tall as it sit (which is about 4-1/2″ of wingspan). There are 4 eggs laid beside this moth, they are pretty close to the size of a BB. Please let me know if you can identify it. Thank you,
Nick Mankwald

Hi Nick
It looks to me like you have a female Columbia Silk Moth, Hyalophora columbia, a smaller and drabber relative of the Cecropia Moth. The Columbia Silk Moth is similar to the Cecropia, but lacking a red band in the hind wing. It is found in forested regions of Canada and New England.

What is this bug
Hello
I just moved into a new home and there are a few trees that need cut down. I am currently cutting down some Shagbark Hickory trees and this bug is all over the trees. We live in Western Pennsylvania. Could you please tell me what it is and if it is harmful? Please see the attached pictures.
Thank you,
Neal

Hi Neal,
Judging by the mating activity evident in your photo, you might soon have a new generation of Painted Hickory Borers, Megacyllene caryae. They attack hickory, black walnut, butternut, osage orange and mulberry. The female lays eggs after cutting deep pits in the bark. Larva bore inward and pupate under bark. Adults emerge in the spring.

Strange Fly
Can you tell me what this is? I noticed a lot of them flying around this weekend (May 7-8) where I live in Newport News, Virginia and tried looking them up on the net, but the closest I could find was a Pyrgotid Fly, mostly because of the wing shape and coloring. It is about 1/4 to 3/8 inch long. A local entomologist said it could be a seed maggot fly.

Hi Harry,
We contacted Eric Eaton for assistance with your photo. He writes: “The fly may be an Otitidae (aka Ulidiidae) species rather than a Tephritidae. I am just learning about the flies, though:-) Try the Systematic Entomology Laboratory at the Smithsonian, going to the Diptera pages. Also try Bugguide, as I have seen this critter there, again, in Otitidae.” We did some additional internet checking, and while we couldn’t locate your exact species we did find that this family is known as the Picture-Winged Flies as well as this information: “Larvae of most Picture-winged Flies feed on decaying vegetation while a few are root feeders.” There is also some confusion between the Platystomatid and Otitidid Flies as both are commonly called Picture-Winged Flies. Your fly is definitely not a Pergotid.

NOTE: Delphinia picta
(05/11/2005) Hi, I saw the photo submitted on 05/09/2005 by Harry of the picture-winged fly. I’ve photographed several of these in Atlanta. They were identified as Delphinia picta.

Brown Recluse -like spiders
Will you have a page dedicated to the brown recluse anytime soon? I used to live in Moses Lake, WA where we had many spiders that looked similar to both the Brown Recluse and the common Wolf spider but I can’t tell them apart. My grandmother was bit by a recluse somewhere in the vicinity and I can’t tell which spiders are which! Now I’ve moved to Edmonds (just north of Seattle) and I recently found another spider similar to our Wolf spiders, but it was slimmer and held it’s front legs in a tighter, more predatory manner (though it could have been a "defensive" manner cause I had tried to squish him twice and failed). Any pictures and size approximations would be wonderful. I would also like to tell you that you have an extremely useful site. It happened to be the 3rd hit on Google for "Small bug with pincers" when I was searching for a pseudoscorpid that I had just found. Oh, and my grandmother is ok, by the way! She was bit on the scalp, and was noticing that her heartbeat had sped up and she was losing mobility in part of her face and went in to see the doctor within 3 days of being bit. The doctor was the one who classified the bite. — Thanks much!

Hi Megan,
We cannot be comprehensive. We post images and identification sent in by our readers. We will post a Brown Recluse photo as soon as we get one. Glad your grandmother is OK. Because we print our readers’ letters verbatim, the search engines find our site based on layman’s terms, and not scientific terms, which is why we get so many site hits.
