Hello,

can this be Tachina magnicornis? It it a female, though... On Leucanthemum vulgare on a meadow at forestborder (northwest Germany).

Hi Jürgen, I think your images are all T. fera. Included is a collage of a fly showing two of the significant characters: the slim band getting broad on tergit 5 and the front tarsi being dark brown to black!
(also: in fera, the male's fore claws are very long and the male usually do not have oe.)

Greetings, Eric

I agree, but the vertex is unusually broad.
Please note that all colour features are unreliable.
To be honest, ALL features are unreliable, except male genitalia ( very distinctive)

Thank you, Eric and Theo!

I have taken photos of hundreds of Tachina last year. 99% are straight forward T. fera. I only posted some (for me) ambigous specimens. Because I was unsure interpreting the other characteristics correctly, I concentrated on the arrow/triangle shaped end of the abdomen band. Almost all look like this (which was not the case in the above specimen):
