Dilophus

Yes, there is a ring of spines at the apex of the fore tibia and a ring near the mid point. Bibio lack those, and have two strong spurs at the apex of the tibia only.

Difficult to get to species in both families, from a photo, but the dusky wings should make this febrilis, the commonest species.

Relevant to the name of the

Relevant to the name of the genus is the double spiky crest on the pronotum. 'Di lophus' = 'two crest' in Greek. Bibio don't have these - the pronotum is smooth. You can see them well in the first pic.
