Very nice find.
Have a look at the arista: clearly all segments elongated.
Given the short stalk and habitat:

Germaria angustata


Congratulations

Wow - that is extremely rare - worth informing Peter Tschorsnig of the location :)

Thanks! I met this tachinid yesterday (20.06) early afternoon, dimmed sun; it was standing on sandy ground populated densely by various aculeata and their parasites, near a young oak tree. Place was an ancient Vistula valey south of Warsaw between Ursynow and Wilanow. This was a dry site surrounded by wet meadows. The fly was not shy, but possibly flight was impaired because of some damage to wings.

I will email Peter to draw his attention to this thread :) This species is normally restricted to sandy dune systems along the Baltic coast and is very rare and possible threatened too.

G. angustata is known from inland sand areas (Kootwijk on the Veluwe, NL), but indeed, very rare.
However, I guess the sand dunes along Wisla river might be quite like seadunes, since the Wisla is a pretty large river.

Mail J. Ziegler, he is reviewing Germaria

The place was pretty far from Wisla, some 2-3 kilometers.
