Hello, Pierre Duhem : France : Saint-Mitre-les-Remparts : 13920 : 08/05/2016 Altitude : 53 m - Taille : 8-9 mm Réf. : 162853 I had initially thought it was C. pagana, because of the orange antennas, but another member of our French forum thinks it is C. sorror. The antennas of this later species are indeed smaller and rounder. What do you think about it? Thanks in advance. Edited by pierred on 17-06-2016 07:44 Pierre Duhem |

Can C. scutellata be ruled out? Greetings, Henrik |

I believe that the third antenna segment of C. scutellata is brown.

Hello pierred and piros, Humeri and tip of scutellum are orange so scutellata group, excluding the possibility of C. pagana. Red antennae -> Cheilosia sorror. Greetings, Ectemnius |

I'm afraid I don't understand what you said. According to van Veen, C. scutellata is member of the C. pagana group, isn't it? What is your conclusion?

Hi pierred, The scutellata group (I thought there was something like that, but it might be just something I made up  ) is artificial just like the pagana group. I referred to the scutellata group as the species with yellow humeri and top of scutellum. Those being in North-West Europe C. scutellata, C. sorror and C. longula. Of those three only C. sorror has a bright red third antennae segment.Greetings, Ectemnius |
