Sorry for a duplicate. I was in doubt and gave a search for my name at this Forum, however, none of the search results gave me that previous posting. So, I decided that was my bad memory and posted the photo. But that WAS my bad memory!
Pour cette bête là j'opterai pour Oberea nigrocincta cependant il vous faudra vérifier fermement car la détermination des Oberea par photo (à moins quelles soient très caractéristiques !) relève de l'exploit !
