Indeed Anthomyiidae, but I must admit, I find it difficult to say something about a possible genus.
It feels Phorbia, but then the hindtibia should have pv and midtibia an av seta, and this is not visible on your photos (a bit blurr)
I also would not want to exclude Botanophila though...
So....one to store in a folder "unresolved" on your computer.....
