Fly - Chalcosyrphus chalybeus

Fly - Chalcosyrphus chalybeus
Newport News, Virginia, USA
May 11, 2005
I don't know a lot about flies and didn't really know where to start for this one. Is it some kind of robber fly? It was a pretty good size (a little less than an inch).

Moved from Chalcosyrphus.

Chalcosyrphus? (Syrphidae)
Looks similar to Patrick's photo. He gave a size of 18 mm and mentioned a red abdomen, which can be seen in your full-size shot.

Chalcosyrphus is indeed a possibility. The genus got split-off into at least twot least one all-black species that is an astonishing mimic of the blue mud dauber (Chalybion californicum), right down to flicking its wings while at rest.
