Hello, In the south of France on April 21, 2025. The insect measures 7.5 to 8 mm long. I'm thinking it's a Bombylius, but I've never seen this wing venation on the Bombylius that I've already photographed. Thank you for your help with the identification.

Hello Liliane, did you check the photo's size and "no spaces, no dots..." in the filename? See https://diptera.i...p?cat_id=2 A lateral photo showing a femur could help. Greetings, Eric Kloeckner |

This is precisely a photo where you can see the femurs! The title 210420253 and the weight of the photo are the same as those in the first photos. I would send it to you by private message, but I see that attachments are not allowed. |

I've received the photo and try to add it to your thread. I'm not sure but I think it could be a female Bombylius cinerascens - I've never seen it. EDIT: I also cannot add this image... Edited by eklans on 22-04-2025 14:10 Greetings, Eric Kloeckner |

I can't find this particular venation (circled in white) on Bombylius cinerascens. But I don't know if it's important? Liliane D attached the following image:  [162.46Kb] Edited by Liliane D on 22-04-2025 17:29 |

I've seen that, too, and I do not think, that this stub is relevant for an ID: If you look at this overview of some Bombylidae wings: https://galerie-i...ref=155933, you'll find the stubs on several species' wings. In Exoprosopa: https://galerie-i...ref=354544 you'll see a complete vein instead of the fragment. Unfortunately I cannot give you a scientific explanation for the phenomenon but I think it has to do with evolution. Nota bene: I'm still not sure, if B. cinerascens is correct - if you'd add it to the threads title, we would have a chance to attract an expert. Greetings, Eric Kloeckner |

Thank you for your research and for the links. Indeed, this interrupted venation is not a specific feature of a species! |
