Jandre69 has it in one... Pompilidae wasp and Palystes rain spider... I have seen this twice before, the first time I stumbled upon the wasp busy digging a hole with the paralyzed spider lying next too it, kept stopping its work to check that the spider was still there

The second time I almost caused a car accident... My self and some colleagues were on a field trip and I saw a wasp dragging a BIG spider across the road... I yelled because I thought we were going to run it over! scared the driver out of her skin

but she stopped for me so we could look (gotta love good friends who tolerate our obsessions) he was a feisty wasp! and person that came too close got charged! you could just hear the voice over: "you shant have it! tricksy humans! my spider! my precioussssssssss"
