This time on
Betula. Sitting motionless when there's no sun and starting to move with typical short leaps when the sun was shining.

The question you asked me today is easy to answer - it isn't M.jacula.
Looks similar to Medetera in your previous post.

Thanks Nikita - so it seems I have some more non-jacula pix made in last year...

Why not Medetera borealis Thuneberg, 1955: Ann.ent.Fenn. 21(3): 135 ** Type locality: Finland: Joutseno, Turku. Palaearctic: Sweden, Finland, England, Norway, Czech, Russia, Japan *
Anyway, please check genitalia.

I disagree :)
The haltere looks rather dark. The first
Medetera I usually find in the spring are
M. infumata, M. pseudoapicalis and
M. tristis. Of there three,
M. tristis is the best match with the photographed fly. So I'd say
M. tristis, although not with 100% certainity.

Today I've got two specimens - from 21apr (on photo) and another on from 22 apr. Halters dark, postocular black, everything else for
Medetera tristis including genitalia.
But in

halter is yellow, doesn't it?

Yeaasnnoooomaybe. The haltere colour isn't quite as nicely divided to pale/dark as one could hope in these flies. For the "tristis-apicalis"-group, I would only trust identifications based on male genitalia.
