I pictured this Diptera in Belgium, on 2021-08-12.
I searched to ID it using wing venation but could not ...
Can you help me ID it ???
Thank you very much !

The wing venation points to Rhinophoridae, as cell r4+5 is distinctly petiolate (this character is found also in Tachinidae, but they look different). The long petiole is typical for genus
Stevenia, but that's it I'm afraid... The key in
https://www.mapre...24p041.pdf asks for characters that are not clearly visible in your pictures.
S. deceptoria bears a certain resemblance as to conspicuous dusting but should have reddish palpi and a reddish tip of the second antennal segment. So let's stay with
Stevenia spec.
