Hi,
I found this March Fly in the Harz mountains on 9.10.2020. Could it be Bibio clavipes?

aany chance of getting a better (sharper) view of the front leg ? Are we sure this is not Dilophus ?

Sorry, but I have no better image of the front leg.

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).

Yes, but check my review in Nederlandse Faunistische Mededelingen. Most traditional features, as summarized by Haarto, are proven unreliable.

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
