This would be B. lepidus: the pterostigma is large and dark. Good find ! Locality ? Theo Zeegers

Most/all species of Dilophus have a large second (autumn-)generation, so opposed to the genus Bibio this is not special. Dilophus is recognized by short apical spines on tibia 1 and and additional row of spines halfway the tibia. Hardly possible to see in the picture, though. Dilophus febrilis is the only common species in most parts of Europe. Theo Zeegers
