Damn, tarantula hawks are hard to get. So fidgety and flighty. They're unspeakably cool, though, so maybe I should go out with a net and an ice pack. I think this might be Pepsis mildei, given the large size and orange antennae. Are there other options?

These wasps were burrowing very rapidly in the sand at the Ginkakuji (Silver Pavilion). They would move back and forth in short lines digging tunnels which they would plunge into entirely upon completion.
