John - I think their range is over most of North America. I've seen them here in Canada and other people seem to report them from all over.
where is this wasp most commonly found? i live in the houston, tex. area and just saw my 1st one today
No, this is not a species ever harmful to humans. In fact, these are beneficial. That's a female searching for wood boring beetle grubs in which to lay her eggs. The eggs hatch and then the larvae eat the grubs. This wasp is solitary, not social, so it never makes a nest. Most wasps are solitary and live in some manner similar to this one, although few have such an impressive egg-laying organ ("ovipositor")!
I found one of these in my back yard. I was wondering if these are harmfull, and if they could possibly be a danger to my little girl. Where do they nest, and come from???
Please e-mail me back about this bug
