Fly on Queen Ann's Lace - Syritta pipiens

Fly on Queen Ann's Lace - Syritta pipiens
Northern, Virginia, USA
July 19, 2004
I have no idea what this is, of course. The enlarged hindleg femur is obvious.

I've noticed several shots of insects that appear to have faceted eyes like this. Is this a photographic anomoly or are they flat surfaces? If some eye surfacses are flat is that diagnostic at any level?

As usual,thanks for any help,

I'm pretty sure I've seen the same fly here in North Carolina, at the same season, and on the same plant, Queen Anne's Lace:

Flower fly
The flower flies (family Syrphidae) are an incredibly diverse group, and whenever I find a fly new to me, I have learned to first eliminate the Syrphidae as a possibility:-) This looks like a species of Syritta, but can't be positive. Nice image, John!

Syritta pipiens
It is Syritta pipiens, also very common in Europe. The other Syritta species I saw in the Nearctic list, S. flaviventris, has a distinct long protruberance on the ventral side of the hind femur ( It is absent in this species, so it must be S. pipiens.
