Great Golden Digger Wasp

Sphex ichneumoneus

Sphecidae

A large, striking orange-and-black solitary wasp that looks alarming and is completely harmless to humans. Female visits flowers heavily for nectar, hunts grasshoppers and crickets for her larvae, and aerates soil with her burrowing. One of the most beneficial insects a garden can host.
