Banded Argiope

There were many of these through this disturbed field. Also almost all had some prey wrapped in the center of the web. The first two photos I'm fairly certain the prey is a Campsomeris dorsata, a Scoliid Wasp I've photographed here before. The last photo was a different near by spider (same species) that had, I believe, a Metallic Green Bee of some sort (also seen here at other times).
