Hi all
My first thought was Chrysogaster, but the antennae do not seem right.
Murato, Corsica, August 2008, Approx 8-9 mm.

Oh, and by the way, it IS a syrphid, isn't it ?

Cheers
Philippe

It IS a Syrphid, probably Chrysogaster cemiteriorum, female.

I think the third antennal segment is too long for any Chrysogaster species. It's an Orthonevra, which is also indicated by more or less recurrent marginal crossvein M1. Riponnensia would also be a possibility, but the only species with an elongate 3rd antennal segment is R. longicornis, and in that species the antennae are even much longer. So, I think it's an Orthonevra species, but I don't know which one.

I agree with Menno, certainly Orthonevra, and it looks like Orthonevra nobilis, but that's an educated guess!
