Badem, RLP, Germany; 10 Sep 2021; cf Drosophilidae Fam fly; can somebody ID it? It is sitting on a window sill eating an aphid that is laying eggs (4).

Thanks for your help. Whatever the insect is that it is feeding on, it laid 4 eggs while I was taking photos.

I think the prey might be a gall midge. Certainly no aphid because I can see halters.

It has the short first tarsomere of the Cecidomyiinae+Porricondylinae clade.

Thanks, to both of you for the help. I had switched between Aphid & Fly a couple of times. I'll look at it again with this information.
