Hello
the pictures were taken in august and september at Lake Thun, Switzerland. Are these flies all Tachina fera? (And if possible: how can I see it?).
Thank you! Maja

No
the ones with black legs, esp. black tibiae, and a strongly contracted black vitta on the abdomen are Nowickia, most likely N. ferox.
Tachina has the tibiae and part of tarsi reddish (with T. grossa the obvious exception).
