I will post a coulle of more pics. This fly is pinned on a tag and it isn't done very well since of its size. Nevertheless, I would be interested in it is a different species. Perhaps, I can catch or photo some more. I think they are relatively commmon here.

Ok I double checked and this might be the second record of Syritta flaviventris fro the US. The first specimens were from Texas and Mexico, published in 1990. Please look again at your specimen and it should have a a large tubercle at the base of the hind femora. And the other character is that it does not have the spuriouse vein which is characteristic for all Syrphids. I very certain that it is this species, after I looked up the publications! Catch some more and find out if they are all flaviventris or mixed with the very common (but also introduced) pipiens! Great find!

Martin, I thought you might want to know that I have spotted another of these flies in the adjacent county. Check BG for my improved photos of my unpinned specimen. I am sending this one to Dr. Steck, a dipterist at the FL Arthropods Collection for verification.

Yep this is another one. MAybe you can publish a short note in a journal about these findings. I think it is always important to document the new invading species (even if they are no pests). I know Gary, and I am sure he will confirm my identification, but it is good if you could deposit a specimen in Gainsville.
Cheers

Who would have thought such a tiny poorly mounted insect could create a stir? I almost didn't post a picture and put it in my collection as unidentified like so many others. I will post a couple of more pics and try to find some others. Thank you for your information and research. It amazes me that so many others on Bugguide are so knowledgeable. I guess that's why specialization is necessary. I am a generalist.
