Hello, all, This one was photographed at Bonneval-sur-Arc, in the French Alps. Alt 1800 m . In fact I did not notice it at the time, it's on a picture I shot of a butterfly! But the place was alive with Cheilosia derasa females. This one is a male, obviously, and I was wondering if it might be the same species. Notice the rather conspicuous dark spots on the wings, that female derasa don't have - I could not find a picture of a male C. derasa, hence my query. If not Cheilosia derasa, does anyone know what it is ? Thanks for your help Philippe Philippe moniotte attached the following image:  [132.84Kb] Edited by Philippe moniotte on 18-02-2013 20:42 A beautiful hypothesis can be slain by an ugly fact. |

Nope, if it has spots on the wings it looks more like a male Cheilosia caerulescens...
