Dear Christine,
fantastic pictures!!!
If I'm able ... I'll try to move your post in the biology posts.
Many Chrysidids are reported to be parasitoids of Odynerus spinipes: Pseudospinolia neglecta, Chrysis ruddii, Chrysis viridula, Chrysis mediata, and we also have some doubtfull data as those for Chrysis bicolor.
Based on your beautiful pictures it's impossible to be sure about the identification, however, I presume that your Chrysidid could be Chrysis mediata Linsenmaier, 1951.
Cheers
Paolo
