Hello,
I have photographied this little fly on a plant of my garden (Picris hieracioides) in Lille (North of France) on August 30th 2022. It is not easy to separate flies of the genius Tephritis and I am hesitating between three species : T. neesi, T. divisa and T. separata. Are you agree with that ? Perhaps these species can hardly be identified from my photos, nevertheless I am very curious to have your opinion, is it possible to name the species of this fly ?
Thanks in advance,
Dominique

Seems to be T. divisa for its morphology. Secondly T. divisa is known to place its eggs in flower heads of Picris hieracioides.

Thanks Günter ! For this proposition (T. divisa) and for your explanation.
