Another body snatcher

I saw this on the beach. It flew onto my sun lounger and I was able to get a quick snap of it with my phone before it flew off again. I've yet to identify this wasp but it was approximately 10mm in length. I was initially thinking it was perhaps Euodynerus megaera however I think it is too small for this species. I'm guessing it's a potter wasp of some kind. The hunt continues!
