Cylindromyia interrupta. Given your location other similar species are unlikely.
C. pusilla and
C. brassicaria are also common in middle Scandinavia, but other species are very rare (in fact the only have those three species in Finland).

First of all, my apologies to Susan.
She is right, it fits my description.
It's difficult te characterize any of the 400 Tachinids in one sentence.
The topcel is not closed, but stalked, meaning the stalk is clearly present. I agree that the difference is gradual, however, this wing venation doen not fit Eriothix.
Moreover, the abdomen is more cylindrical (!) and the reddish lateral spots are larger (and therefore less lateral).
SO Cylindromyia.
I'm not sure about the species.
It is either C. interrupta or auriceps.
I seem to see small scutellar apical bristle, maybe this can be checked on the original photo (?). They are small, no problem.
In that case, it would be auriceps, which is absent in Finland (Kahis) but present in Sweden (www.faunaeur.org).
On the other hand, the pattern on the thorax suggests interrupta (in which case apical scutellars should be absolutely absent). However, difficult to see the thoracic pattern on the picture.
So, one of those

Great.
My geographical knowledge of Fennoscandia is insufficient to grasp the consequence.
So, my turn to ask a simple question
is Stockholm north or south of Ostergotland ?
Theo
Thanks.
