Hello,
I observed this Chrysis of 9 mm on 18 July 2020 at an altitude of 1145 m on the trail that goes from Casset to Le Bourg on a sunny slope (La Chapelle-en-Valgaudemar, Hautes-Alpes FR05). I noticed that the middle part of the mesonotum is almost black and the apical rim of T3 is dark blue-purple. Could it be Chrysis graelsii ?
Thanks ! Best regards.
