Fly Hunter - _TNY_8345S2
The field digger wasp (Mellinus arvensis) is a solitary wasp who catches flies and bury them in egg chambers dug in sand/soil. I say solitary in that each female digs her own nest, but they still live in colonies and can still dig very close to others (like 10 cm) which was the case in my mother-in-law's garden where there suddenly were a whole bunch of holes dug in the ground.
I staked the place out and quickly discovered that these were the culprits.
This particular specimen was sitting still on a wood railing, so still that I managed to take two photos which I stacked manually using Photoshop into this image .
