Ouahh nice finding : Chrysura rufiventris have a thick border in the profil view (fine in trimaculata & refulgens). In the half north of France, there are not many data (in my knoledge, only in ...

Thanks Paolo!

Interesting that C. rufiventris is expanding its range so swiftly northwards. Even into regions where its host has a very scattered distribution. Especially so, since C. trimaculatus is apparently not able/liable to do the same.

Hi Vladimir,

I agree with Alex, it looks like a Chrysura trimaculata.

Cheers
Paolo

Thank You, Alexander! I'm no expert, just taking pictures of insects. Let it be Chrysura cf. trimaculata.
