Syrphini sp?

This appears to be Ocyptamus
This appears to be Ocyptamus fuscipennis.

There are no similar species with this degree of wing infuscation.

If abdomen shape and wing infuscation isn't enough:
I believe strongly concave sides of eyes rules out all look-alike genera occurring in temperate USA other than Toxomerus, Ocyptamus, and Hypocritanus

Sorry, Pelechinobaccha would
Sorry, Pelechinobaccha would also have similar eye margin--but can be separated like Hypocritanus by different wing pattern. Toxomerus do not have petiolate abdomen.

Dioprosopa and Baccha are the other genera with petiolate abdomen and don't have a comparable eye margin.

e.g. [thumb:495179]
I went thru the O fuscipennis a few weeks ago and found a significant minority with a leg pattern / haltere light yellow as shown here and typical for P costata. I also can remember many O fuscipennis with wings as shown here, I don't remember any O costata--maybe I missed them.

This is either Pelecinobaccha
This is either Pelecinobaccha costata, or Ocyptamus fiscipennis. This is a freshly emerged specimen, and therefore does not show the mature color pattern on the wing or legs. The yellow on the hind legs looks more like O costata, the rest more like O fuscipennis. But it is not the best picture and all the potential species are rather common, so I thought it is not worth the time to try to figure this one out ;-)

Thanks, Martin!
Thanks, Martin!

The abdomen appears to be pet
The abdomen appears to be petiolate, as well, so I agree with your thoughts here.

Dr Hauser told me this one has no potential

Frassed: no further id potential here, bad angle
