Visited Antelope Island today with a borrowed camera. Looked down and saw a black wasp flit into a burrow. I thought "Hey, cool, a spider wasp, I'll catch her as she comes out..." I did not realize that she was at the very end of the process: I was almost standing on the spider she had paralyzed!

Prey is probably* a male Neoscona oaxacensis, which is surprising to me, I didn't know spider wasps would take orb weavers for prey.

* I am not a bug expert at all. The last spider I confidently identified turned out to be a Jack Russell Terrier. But Antelope Island is absolutely HEAVING with N. oaxacensis--literally dozens of adult spiders per cubic meter all around the visitor's center--and the colorations on the spider match the hundreds of males that were parked in webs all around. Males also seems far more likely to leave their web and go courting, making them prime suspects for a good wasp-mugging.
