Black Horsefly
Great Web site! I’m the airport photographer at Cottonwood Airport, Arizona. I happened to be in an open hangar Monday (23rd) afternoon and spotted this black Horsefly on the floor. It was a very hot day and the fly appeared to have trouble flying — in fact, it acted like it was exhausted and really didn’t want to move. I just happened to have my Canon SD950 camera with me that day (I normally have my Nikon D300) and decided to try an get a picture of it, using Macro mode. (After all, I photograph everything else that flies!) I’m somewhat pleased with the result and thought I’d share it with you. If you care to use it, you have my permission. Keep up the good work.

Howdy to you too Gordon,
This isn’t a horse fly. It is a Bot Fly. The larvae are internal parasites of rodents, and depending upon the species, other mammals.

Agapostemon Texanus?
Hey there! Some internet research pointed to Agapostemon Texanus – does this sound right? I live in Portland, Oregon and have never seen these before. If it is, it looks like their range is nation wide. These guys appear to be somewhat common on your site.
Also, most sites I’ve seen have been primarily concerned with identification. I’m interested in a bit more, like where they nest, behavioral patterns, etc. Any good links you can recommend? Thanks!

This is a Metallic Green Bee in the genus Agapostemon, but we are not certain the species is texanus. BugGuide shows reports from the west coast of Canada, Washington state and California. Despite now having any submissions from Oregon, we would take an educated guess that Agapostemon texanus can also be found there. Hogue writes: “They nest in tubular burrows dug in the ground, often in clayh banks.”

Stag Beetle?
This bug was out at the heat of the day "running" toward me (twice)from several feet away. It would stop in front of me-both times on pavement in the sun. The one in the picture posed for several shots. It is about 2 cm long although I did not have a ruler at the time. I am curious as to what it is and if it will help or harm my gardens/trees. We live in CA within 2 miles of the beach. Never seen it before or since. Thanks for you help. PS I let both go on their way

This is a species of Caterpillar Hunter. We believe it is Calosoma semilaeve. We received so many identification requests from Southern California in mid May, we were prompted to declare is a secondary Bug of the Month. The species is prone to periodic population explosions, which we beleive can be attributed to the rainfall pattern of last winter. That pattern produced lush vegetation and many caterpillars, the food of both the larval and adult Caterpillar Hunter.

What’s this bug??
Hello Bugman!
I have attached two photos of an insect that I would like to have identified. I am in Chicago, Illinois. I have recently noticed this particular species (with moderate frequency) on my wooden porch. Is it some type of termite, or something else entirely? Just wondering if we have to be worried! Thanks in advance,
John in Chicago

Hi John,
This is a Soldier Beetle, Trypherus latipennis. We found it on BugGuide.

black beetle with white shoulders
Today, I noticed an oddity while mowing the grass. There was an orange stink horn growing under a tree. It is a fungus that emits a smelly gooey substance and attracts flies and other insects to carry its spores off to another location. Its odor is like something dead. Along with a fly and another beetle, it also had attracted 2 large black beetles. They are flat black not shiny. They are shaped like a dung beetle, but the shoulders (middle section) are bright white with a little design. Notice that the beetle is almost as wide as it it long. Could it be a type of scarab beetle? Its head is also black and it was certainly attracted to the odor of this stink horn. Could you tell me what it is? Thanks!

hi Dorothy,
The beetles in question are American Carrion Beetles, Necrophila americana. You can read more about them on BugGuide. The other beetle also looks like a Carrion Beetle, but in the genus Heterosilpha.

Dear WTB,
My brother and I spotted this beautiful beetle near Munson Falls, on the Oregon Coast. We are wondering what kind it is? Thanks,
Sarah Kanz

Hi Sarah,
Your beetle is a Ground Beetle, Scaphinotus angusticollis. We identified it on BugGuide.
