Hello,

www.galerie-insecte.org/galerie/image/dos215/big/5ds34146.jpg
Pierre Duhem : France : Bessans : 73480 : 04/08/2018
Altitude : 1745 m - Taille : 5-6 mm
Réf. : 215885

Using the key by Reemer, I had concluded that it was O. trilineata.
But somebody argued that it was O. locuples. On our French forum, we have a picture from the Pyrénées. Both photos in DI gallery are from Tyrol. On the other hand, the knees of my specimen are blackish.

Can somebody say something about this?
Thanks in advance.
