This fly also has a Medetera-ish look to me.

Location: On wooden railing around a pond (Helsingborg, Sweden)

Thanks!

Almost,
I'd say that more probably truncorum than jacula

Dear Iagura,

Well, I would like to add not to stick to M. truncorum as possible species although it is most likely that your specimen belongs to this species.

Please, note that both M. saxatilis and M. dendrobaena are very alike and only differ in the females by a different wing venation (which is not visible in your picture), and the size of the preapical bristles on the hind femur.

It's definitely not M. jacula, as Nikita points out correctly. This species shows one small dorsocentral (dc) bristle in front of 4 strong dc.

Cheers,
Marc
