Mite covered sepsid
Unknown ensign fly, Nemopoda speiseri (Sepsidae) with phoretic mites (ID-cred: P. Beuk)
Size: 6 mm
This little fly was found on a very decayed moose carcass. Almost nothing remained except for the hoofs and a few other bones. Still you could find a few carrion associated bugs, such as this one even though you had to look really closely in the crevices around the hoofs to find any soft tissue left.
I'm adding a few more shots from the carcass in the comment-section.
Thes wings of this specimen seem malformed. It was able to fly but only for shorter distances.
