Hi! The basicosta on this fly doesn't look to be very yellow, could it be other than C. vicina? Unfortunately I didn't get a pic to show the spiracle. 17th March 2011, near Lincoln UK on Mahonia. 2 pics + 1 crop. Janet

yes, the basicosta is yellow, moreover, the reddish gena confirms vicina. Theo |

OK thanks, I guessed as much Theo but one can't always be sure when the yellow is not very yellow and there is another species with a similar coloured gena I believe, such as C. uralensis. I will keep looking!

Whenever the basicosta is clearly lighter than the epaulette, it is considered 'yellow'. Your first picture shows this nicely. Uralensis and loewi are pretty rare in Central Europe. Best strategies are: * go high in the mountains * collect all Calliphora between october and march (even then, vicina will be dominant) Theo |

Thanks for the tips Theo. I don't live very near mountains, and to take a specimen it would have to drop dead in front of me. I do have C. vomitoria, it can sometimes be confusing when viewed from above as the face often looks pale, but viewed from below looks black. I have a pic of a female which viewed from the side has a pale face which looks white flushed with pink, yet it has a mostly red beard! This male I only got one pic of on 16th November, I've cropped it to show the basicosta which is black. I haven't named it but I imagine it is C. vomitoria. blowave attached the following image:  [138.02Kb] Edited by blowave on 20-03-2011 20:13 http://cubits.org... |
