Can someone ID this fly that I think is a Sphaeroceridae? Near the sea, south of Sweden, December 20. Best regards, Thomas

Similar to pictures I have seen of Crumomyia pedestris, but I do not know if there are other similar species.

The only wingless European Sphaeroceridae I know of is
Aptilotus paradoxus. Marshall (1999) gave a generic diagnosis here:

(Edit: Based on above comment
Crumomyia pedestris is a wingless European Sphaeroceridae I do not know of. Looks similar, although reduced forms often converge on similar appearance.)

Hello,
This is indeed a Sphaeroceridae of the subfamily Copromyzinae. Specimens can be anything from nearly apterous to fully winged in some species. This looks very much like Crumomyia pedestris, however more species can have reduced wings. See:
