4-16 July, 2020. Val d’Arda, PC, Apennines, N Italy. I’ve been lucky with getting Chrysidids identified lately; this one looks a bit more ‘average’ so perhaps difficult? Head and thorax blue-green, sometimes looking all blue, sometimes more green in parts, eg. scutellum. I thought at first these might be two different species but I’m almost convinced they are one. Apical rim of T3 blue with four low rounded bumps. To confuse things there was one similar wasp with strong points on T3 apical rim; I don’t know if this is a different sex or different species (last image). All help gratefully received!
