Wasp and spider

I didn't see the wasp killing the spider but I witnessed our six-legged friend taking the bacon home to the kids. The kill was much to large and heavy to fly with it, so it was being dragged across the floor of the front porch. It took some effort but the wasp eventually pulled it up the side of a chair and into a vase, where she had dug a hole into the dirt to make her nest. I can imagine that a spider of this size must have provided food for the young ones for some time.
