I badly need a second opinion on this Tachinid. It was captured yesterday (16. vii 2011) while feeding on Pastinaca sativa in a dry meadow in the middle of deciduous forest not far from Copenhagen.
The fly is really quite distinctive with the brownish infuscation along the front of the wing; the scutellum has five pairs of marginals. The subapical pair is converging. The apicals are weak and hair-like; the basal part of the arista is thickened and yellow; palps yellow. Body length ~ 4 mm.

It keys out without much trouble both in the Central European key and in CMPD but the result is surprising (or outrageous) and because of this I am wary. If I'm right it expands the range of the species quite a bit – a result of global warming one would say.
I won't give away the species I arrive at yet, but let you guys have a go at it first!

Some features not seen in pictures:
-prosternum bare
-occipital hairs black but some light hairs present ventrally above posterior mouth edge

I am very interested in hearing your opinion before I divulge my outrageous species name ;)

Regards,
