Hello Gert, the female fly is not
Helina evecta. The abdomen doesn't match, the anterior spiracle is too dark and it sits too high.
H. evecta sits low to a surface like a Pollenia. The anterior spiracle of
H. evecta is golden yellow.
I think that Muscidae is correct and i think that it might be Helina. I have not seen something like this before, so i cannot help with a species.
