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).

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.
