Wasp of the Weekend

Wait a minute, who’s this running over the dirt spoil piles of Eastern Cicada-killer Wasp burrows?
There’s more than one big blue-black wasp species out there, and they can be difficult to ID at a glance. But this one scurrying around the Cicada-killers was giving a clue just by her actions. That and the long “neck.” The Steel-blue Cricket-hunter Wasp (Chlorion aerarium) is evidently darker in the east than in the west. According to a note on bugguide.net, they sometimes dig their nests next to Cicada-killers. As the name suggests, Steel-blues hunt crickets for their larvae, so these two wasp species are not competing with each other.
