Death Grip

You know those days you go out and are having sort of a fly day or a reptile day etc...well it had been flies up to now.

On a lovely wood bench in Brede High Wood, there were a lot of flies sunning, so we were looking for anything interesting when this wasp swooped in, wandered around for a second and then BAM! Grabed this juicey fly. A small struggle ensued and the deed was done, seconds later the wasp was away with her catch.

No shots of her to get a good ID but if anyone has any idea what wasp this is I'd love to know.

Update: Thank you soo Much Andrew Grace1 for IDing this wasp for me as Mellinus arvensis!
