Is this a Sphengina sp.? Measured 4.4 mm to the tips of the wings. Visiting Spirea flowers, 5 May 2011. I'll post a lateral image in a moment, it was from two days earlier but I think is the same species.

Stephen: Looks like Sphegina to me. Ours (SW Ohio) have just started appearing as well. They love rose family blossoms it seems as that's where I see most of mine. http://bugguide.net/node/view/77419 is a photo of a species I find most in Cincinnati, though I still don't know what it is. Have to catch one some day. Edited by Steve Pelikan on 06-05-2011 20:36 |

This looks like a Sphegina sibirica (yellow version) but I have no clue if this specie exist there too. Better catch a male and send it to a specialist.

S. sibirica doesn't seem to be in eastern north america. For ours, Coovert and Thompson's paper/key serves and I can send you a copy, Stephen, if you email me. Or, you could send me a fly or two. Males are best as Bastiaan indicates. |
