We have an interesting wasp that is excavating a small hole in a crack in the driveway. He does not seem aggressive ….similar in behavior to a cicada killer.
This sure looks like a Steel Blue Cricket Hunter, Chlorion aerarium, to us, and we believe SHE is making a subterranean nest that she will provision with Crickets for her brood. See BugGuide for more information on the Steel Blue Cricket Hunter.
