Looks good to me :) T.nigrohirta is known from southern Germany but it should have darker hairs on the thorax ... it is also very rare so T.ursina is more likely ;)

Thank you Chris, Josef

To jorgemotalmeida: I recognized, that the fly is very true to the place. It always returns to the same place even after massive disturbances.

Yes, once they find a nice sunny place to sit they usually return to it :) They are a classic sign of Spring arriving but I wish they were a bit commoner :)

By the way, Chris, what is the host of this tachinid, I can't find in www? A carterpillar? Species? And: How old can it get (the imago)?

The host of Tachina ursina is unknown.

In tachinid times you can see here the note: "In Kerimäki, one
specimen was sighted sitting on bare ground, but more
than ten individuals were observed visiting the sap runs.
The host is unknown." SOURCE: http://www.uoguel...s/TT20.pdf
