Black and orange fly, or wasp
July 5, 2010
I saw this in my garden and can’t find anything that looks quite like this. It was on my zucchinin plants and was about an inch to inch and a quarter long and seemed to like being in the sun, the main body was bright orange and the tops of the legs were orange also, on it’s back were black stripes or long spots on it. I don’t have a good picture since I was out in the garden and only had my cell phone.

Dear JD,
The Squash Vine Borer,
Melittia cucurbitae, that you have photographed and submitted is actually a moth that mimics a wasp.
