My first thought with this one was that the spider was attacking the wasp; but it's t'other way round. I'd not heard of this creature before.
No interactions present.
I think the spider is Araneus diadematus, so I wonder how it extracted it from its web /retreat
I haven't a clue, but the wasp must run a risk with every spider it catches, especially the larger ones. They can move pretty quickly (the spider that is) so I imagine the wasp is either even quicker, or really sneaky.
yes, that abdomen does seem to extend well beyond the wings now you suggest this genus, initially I thought this was bigger and the wings looked short as they were at an angle

The wings WERE quite short. In picture 1 the wasp was almost (but not quite) sideways on to me. The aperture was set at F2.8, so the depth of focus is pretty short.
Size? About 12mm, perhaps a little more.
As happens so often, it didn't hang around, so this is all I have. I hope it helps.
apparently very difficult, here's one of mine that was acually given a species, I think it's the commonest
I think you're right. Some insects are really diffficult. I have enough trouble with birds ;-). Dragonflies - well, I'm getting somewhere with them, and the commoner butterflies. But wasps and flies should come with labels, if you ask me...
