Re: Spinolia unicolor (Dahlbom, 1831)

No problem for reply 
I make the same observations : I found many Chrysidid (and Eumeninae) in May to June or negin July too (in north east of France, as Besançon).
The Chrysid that I view in summer (between half of July to half August) are : Hedychrum and Hedychridium, some Chrysis (analis, illigeri).
