Hello,

For this one, I don't know if it's L.cylindrica or L.guttiventris.
It's mainly the abdominal pattern that makes me hesitate.

Certainly not cylindrica but I am not sure which it is... there are more species that are similar to guttiventris

Okay, thank you.

I used this key to arrive at guttiventris : http://www.robberflies.info/keyger/htmle/key.html

But according to Fauna Europaea, there are two species in France that are not in the key : Leptogaster nitida and Leptogaster pumila. I can't find anything on them.
