Hi, I found this March Fly in the Harz mountains on 9.10.2020. Could it be Bibio clavipes? Katrin Lena Schneider attached the following image:  [197.67Kb] |

I can see blurry spurs in the second picture, and the r-m crossvein is shorter than usual in Dilophus. It should be one of the late season Bibio. |

If my eyes don't deceive me, the pterostigma doesn't reach coast cell and the hind metatarsus is less than three times as long as it's width (+ wings are whitish?) = male B. clavipes. (Suomen karvasääsket ja maasääsket (Diptera, Bibionidae ja Pleciidae), Antti Haarto, 2012). Greetings, Eric Edited by eklans on 25-12-2020 17:33 |

Yes, but check my review in Nederlandse Faunistische Mededelingen. Most traditional features, as summarized by Haarto, are proven unreliable. Theo Edited by Zeegers on 26-12-2020 09:25 |

Hi Theo, I always start with your key from the Vliegenmepper 1997 and I try to purchase NFM vol. 48 from the EIS for longipes. The traditional features are only unreliable for longipes/clavipes or generally for the Bibionidae? If so, what should I use instead? I have several fotos of couples which I'm trying to identify. Greetings, Eric |
