Never seen something like that till now...
Could it be Euphranta ?
Many thanks in advance for your help :)

Wing pattern resembles Euphranta connexa but that species is smaller and has a completely dark mesonotum (according to Seguy). The straight angle of the subcosta suggests Tephritidae to me.

Thanks Socrates and Paul :)
Paul, do you think we can at least say Euphranta sp ? Or do you also hesitate about this genious ?
Thanks again :)

Several wing patterns are repeated of different genera and I don't know if the same thing could happen with this pattern. Many of the exotic Euphranta species of which I saw the wing pattern have one that is very different, too. So, ... I dunno.

I understand, Paul.
Many thanks anyway for your still appreciated help :)

This is certainly a Euphranta and very probably E. connexa, but I have never seen such a type of coloration of the thorax. Unless this is just a color aberration, it could be a new species. Why not? I'd greatly appreciate any data on its host plant (Vincetoxicum? pods) and an attempt to rear it the next year. Stay in touch, pls.

Hello

I am the author of the pic.

I don't know anything about Diptera's but I am very surprised to learn that the host plant can be important.

I can say that the plant on which was this Tephritidae is Vincetoxicum sp.

I have a pic showing the specimen on the flower B)

The plant's leaf looks to be a Vincetoxicum. In fruit flies (Tephritidae), speciation often is based on specialization to different species of plants. Many species of African origin (Dacus, Euphranta) are associated with various Asclepiadaceae, the family where Vincetoxicum belongs. E. connexa occurs in Europe only (from France to Russia) and very probably has African relationships.

Thanks for these details.

So I can consider this is Euphranta connexa ? Can we be more sure by showing some details ?

Well, I determine it as Euphranta connexa (Fabricius).
