I am guessing that this is a solitary wasp of the Ectemnius or Crabro genus and wonder if the possibilities can be narrowed further.
No interactions present.
I'd agree that it's Ectemnius, and I would guess that it could well be Ectemnius lituratus, but I'm not confident of confirming the exact species from photos.
