Your letter to the bugman: I was gardening when I noticed a little spider being dragged through the grass. I thought at first that an ant was bringing it home, but maybe not. It was making all sorts of enthusiastic abdominal movements I assumed were pheromone deposits. Definitely had wings and a more fly-like face. Thanks!

The predator in your images is a Spider Wasp in the family Pompilidae, and the prey is a Crab Spider, probably a Flower Spider, Misumena vatia. The Spider Wasp will not be eating the Crab Spider. Rather, the Spider Wasp will place the paralyzed Crab Spider in an underground burrow so that the larval Spider Wasp will have a fresh source of food. The pattern on the wings of the Spider Wasp are rather distinctive, and it appears that it might be Dipogon calipterus which is pictured on BugGuide.
