I would like to know if I'm correct: member of the Chrysis ignita group. Probable... But I found out, you never know. So maybe there is more to say (pics not that good I'm afraid).
Location: The Netherlands
Southern part, my garden (on several of my 16 insect hotels)
I think it has 6 teeth on rear end but I'm not sure.
Thanks, kind regards
