Hi all,
I am very interested in finding out what fly this is and what it normally feeds on!
If you need other details, please let me know, I have many more photos.

It belongs to family Phoridae. I have seen a few phorids like this and they belong to genus
Phalacrotophora. The life history of this genus is known quite well, since the larvae are endoparasites of Ladybird Beetles (Coccinellidae) and these beetles are of economic imprtance.
The adults are typically found on tree trunks.

Ok!
That's exactly why I was interested in the first place.
I saw them buggin the pupae of
Harmonia axyridis the multicoloured ladybird and they even seemed to attack a prepupae.
I will see if I can find more about these parasites, or do you happen to know weblinks or literature?
Thanks,
elck
PS I saw that our own Paul wrote about these flies on a begium forum, I hope he can tell us more!

Definitely Phalacrotophora, but there are a number of European species, and we'd need specimens to know which one. The photos are beautiful
