Large spider (wasp prey) - Anoplius

Large spider (wasp prey) - Anoplius
Alexandria, Virginia, USA
June 23, 2004
This large specimen (at least two inches with legs) was being dragged by an Anoplius wasp. My best guess is Dolomedes tenebrosus. It was still alive and moving feebly while the wasp danced in circles between camera flashes.

Anoplius depressipes
I know it's a little late but if that wasp was found stream-side and was all black I'd put money on Anoplius depressipes. If it is that awesome wasp, they use the surface of the water to transport prey. Their tarsi are actually flattened on one side, presumably to facilitate this trans-water transport. They will even swim after the spider if it dives to escape it. They are only known to prey on species of spiders in the genus Dolomedes.
