This little beauty is a Cuckoo Wasp in the family Chrysididae. According to BugGuide: “Parasitoids feed on the larva of the host and cleptoparasites ‘steal’ the host’s food. The food-stealing behavior of cleptoparasite species resembles that of the cuckoo bird and gave rise to the cuckoo wasp’s name. Hosts of parasitoid species include bees, sphecid wasps, potter wasps, sawflies, silk moths, and the eggs of stick insects. Cleptoparasitic species feed on provisions of sphecid wasp nests, which may include dead spiders, true bugs, aphids, or thrips.” They are harmless and cannot sting.
Thank you very much!
It’s really stunning. It must have overheated inside the car.
