If you look at the first tibia, you see a large apical spine in stead of an apical circlet of spines, so it is Bibio. I really don't know which species

Autumn Dilophus from mountains are very interesting, many species like neglecta and borealis.

Please start collecting this material !

In temperate North America there are only three, closely related species of Bibio that fly in October. Males of the species group are black and have swollen hind basitarsi as yours has. You may have a European member of the same species group. If you check literature records for Bibio you should find very few species from late in the year. Here the two common, widespread fall species are B. longipes and B. slossonae.

IN Europe, that would be Bibio clavipes and lepidus.
See other recent threads on this issue.
Can't tell which one this is.
