Thanks for your answer Theo, you're damn right ! Tachinid was my first thought but I didn't know there where Miltogramminae with such as big antennas !

I checked and was attracted by Metopia campestris but after checking all Miltogramminae on LMDI I couldn't find any of them with R4+5 petiolate, they all seems to have R5 cell more or less open...

Do you have something in your mind ?

Thanks.
