Southern France (again). Very slender front to the abdomen. As far as memory serves, this was about 1.5 cms long in a wooded campsite by a lake on farm land.
No interactions present.
I'm not familiar with the French fauna but it's certainly a Eumenid (potter wasp), and at a guess something like Eumenes pomiformis.
I had second thoughts in that direction, but the wing is not folded as it should be in Vespids and Eumenids. I am not now as certain as I indicated above.
You are right but the wings in vespids are only folded when at rest. In the picture they look like they're moving.. or being prepared for take-off etc.
Thank you for this, norwegica. I've found other pictures on Eumenes pomiformis on the Internet and your identification looks spot on - the markings look right and the behaviour looks right.
