Hi everyone, Here is a Chrysotoxum i met last year in massif central, in France, 1300m hight. Unfortunately i didn't catch it. And i don't feel confortable identifying this genus on picture. What do you think?  clovis : France : Lachamp-Raphaël : 07530 : 11/08/2014 Altitude : 1382 m - Taille : 12mm Réf. : 153235  clovis : France : Lachamp-Raphaël : 07530 : 11/08/2014 Altitude : 1382 m - Taille : 12mm Réf. : 153236 Edited by clovis on 21-11-2015 17:05 |

Provided that the 3rd antenna segment is shorter than segment 1+2 (difficult to estimate here) and the femora 1 and 2 have a black basis, it is the spring species Ch. vernale. Completely yellow femora would make it Ch. festivum. The latter can be found till September, which would match better the time of your observation. There is a dark spot on femur 1 in pic 1, however... A Syrphid expert should possibly see more! Regards, Sundew |

I am not an expert but I would have said C. festivum too.

Oups, forgot this thread!  Thanks for your opinion. Unfortunately I have no better picture of femora, but festival looks like a good idea to me too. Edited by clovis on 26-03-2016 20:08 |
