Hello,
A Tachinidae found in North of France, Oxelaere, the 13 june 2017, on a Rosa sp., in a garden
Maybe a
Bessa parallela ?
Greetings,
Thomas

It has discal bristles, so should be B. selecta.

Thanks you very much, Theo ! :D
I don't understand the criteria with the discal bristle, it look similar to the
Bessa parallela I post the other day
But it was near lots of Symphyta larva

Focus on the third tergite (second visible tergite).
The feature, is however, not 100 % but there is no better (known)
Moreover, the Symphyta larvae demonstrate that I am right !
Thanks for this info.

Thanks you for your help, Theo !
The discal part of the tergite is "the edge of the tergite" ?
because if it is the case, on the other one I also see 2 discal setae on tergite 3

No ! Discal is middle, so not basal, not apical, but in between.
On the edge are ... marginals (nomen est omen !)
