Predated Small White Butterfly

Not a great photo per se, but the subject I found interesting. This was one of my Small White Butterfly larva, it had completed making a pupa but a small wasp (likely Cotesia glomerata wasp [thanks to Rockwolf for the likely ID]) kept hanging around the larva and pupa. This is the restult, obviously hatched out. The next photo shows that at the same sorta date a Small White has emerged fine. Photos from under our eve of roof.

What I found interesting was that the wasp sat up on the eve for days waiting I suppose, but did wait until the larva was in full pupation to go away (finish predating it).
