My thought is a Potter wasp in Ancistrocerus - haven't been able to find it.
Found on Parsnip.

Moved from Parancistrocerus. ID is a bit tentative but S. histrionalis appears to be the best match.

A Mason Wasp in PARancistrocerus (male)
I would say Parancistrocerus pedestris, but Dr Buck's expertise is needed to make sure. Only genus is certain.

Probably not
Parancistrocerus pedestris. Because of the apparent absence of yellow bands on terga 3-6 and the reddish suffusion of tibiae and tegula I am leaning towards Stenodynerus histrionalis, which would be a great find!
