Kids! Soup's on!
This nifty wasp, decked out in spiderman colors (her wings are metallic blue at the correct angle) isn't doing battle with that wolf spider who is three times her weight. That spider is paralyzed. He will be dinner for several youngin's. Blech. Creepy thought - getting eaten alive.
I don't know where exactly she was going with her prize, but he was certainly in a hurry. She was also quite flustered when she dropped the meal, but soon found it again and resumed the climb. Soon there will be little eggs destined to eat that spider.
By the way, I think what you are looking at is a Spider Wasp (Tachypompilus ferrugineus or related) with Rabid Wolf Spider prey.
