Hello, everyone, I photographed this hoverfly on July 6th in D, BW, Southern Black Forest (980 m). I estimate the size at 12 to 13 mm. Can you identify it? Greetings Siggi Siegfried Rudolf attached the following image:  [166.03Kb] Edited by Siegfried Rudolf on 09-07-2022 12:51 |

Hi Siggi, I think it's C. vernale: thin yellow bands on tergites antennae: segment 3 < 1+2 femora: base of 1 & 2 black? if not: C. festivum (Fotogids Zweefvliegen, André Schulten) Greetings, Eric Kloeckner |

Hi Eric, thank you for your explanation. The picture is bad, I know. But you can still see that the femora aren't really black at the base. When I look at pictures of C. vernale, the base of the femora is clearly black. I think, in this case there is probably no certain determination.

Hello Siggi, you are right: C. festivum!
