According to Huckett's 1965 key the only two regional species that normally have 4 pdcs are
Egle muscaria (Fabricius) and
E. brevicornis (Zetterstedt), both of which are also found in northern Europe. Does this look like either? The key distinguishes females by shape of head, and I don't have a lateral shot.
Confusing matters, a comment in a forum thread says those two are synonyms but the itis.gov list includes only the later name
brevicornis.
