I pictured this specimen in Belgium on 2021-08-11.
Could it be Dinera grisescens (Fallén, 1817) or something like ?

Hi, I don't think it's a Dinera - possibly a Macquartia?

It is difficult to explain why, but it doesn't "feel" Tachinidae. And it is not. It is Trichogena (true believers of the Code skip the 'h') rubricosa, Rhinophoridae.
The colouration of the antenna is pretty distinctive (but cf. Cinochira in case of the very small black fly).

I measured this specimen on picture : 5,5 to 6 mm ...
Is that enought to make this female a Tricogena rubricosa ?
I already change the name on the record in obervations.be !

Yes, no worries, check the gallery for Cinochira, totally different.

This is Trichogena no doubt (I do correct Rondani's misspellings)

I looked on other subjects in the forum and noted a great variability ...

Yes. On average, they tend to be more reddish. Please note the red tip to,scutellum as well.
