Very nice photo indeed, may be one of the spider experts could give you and ID of the prey. Do you have any other photos?

I think the spider is Araneus

I think the spider is Araneus diadematus, in which case I'd like to have seen how it got it out of it's web / retreat.

That's a great photo of a spider-hunting wasp living up to its name! Well worth clicking through to see in full detail.

I expect the identification is correct, but a second species of Episyron has recently been foudn in Britain, which makes the ID situation a bit more tricky, see:
http://www.bwars.com/index.php?q=wasp/pompilidae/pompilinae/episyron-ruf...

I *think* I can see the "four comb spines on the fore tarsus" that would confirm this as E. rufipes.

Hi Thank you very much for

Hi Thank you very much for your comments. I took quite a few photo's of this attack as it was happening. I will attach another now where you can see the spider and wasp from another angle, hopefully this will confirm identification.

I think this is the other observation:

Great to see another photo of this, but it doesn't add to the identification - what we'd need to see is a detailed close-up of the front leg.

I'm not doubting that these are Episyron rufipes, the alternative (Episyron gallicum) has only been found once in Britain as far as I know, so the chance of yours *not* being rufipes is very small. But on iSpot we like to be as precise as we can about the identification process, so I was just highlighting that wasps in this group do need close examination for absolute certainty.

Hi, Unfortunately the two

Hi, Unfortunately the two photo's I have just added are the only ones in focus that show the front leg. I hope this helps.

Cracking observation

Think I saw this species at Braunton Burrows recently as well, but couldn't catch it in a net let alone take a picture ;)
