Subject: Not a Fly

Like most, I stumbled upon your website looking for the identity of a little buddy I found lazily buzzing through my office.
At first, I thought it was a green bottle fly, but on closer inspection its head resembles that of a wasp’s. It’s also much slower than a housefly–its movements are sluggish in comparison and it seems a lot calmer in general. Even as I type this, it makes no effort to escape it’s tiny (albeit temporary) prison.
Whenever possible, I try to catch and release bugs that end up trapped in my car, home, or office. As such, I applaud your stance on extermination, and appreciate this service you offer the public. It’s nice to see folks passionate about a subject, but it’s even more spectacular when said folks share that passion with others. Thank and keep up the great work!
Thank you for your kind words. You are correct that this is NOT a fly. This is a Green Metallic Sweat Bee in the family Halictidae, but we do not have the necessary skills to provide a definite species. According to BugGuide: “Typically ground-nesters, with nests formed in clay soil, sandy banks of streams, etc. Most species are polylectic (collecting pollen from a variety of unrelated plants)” and “A few species are attracted to sweat, and will sometimes sting if disturbed, though the sting is not very painful.”
