Cuckoo Wasp

Cuckoo Wasp

Hi Madalyn,
This is a Cuckoo Wasp in the family Chrysididae, and you can find a matching image on BugGuide.  According to BugGuide:  “The name ‘cuckoo wasp’ refers to the fact that these wasps lay eggs in the nests of unsuspecting hosts” and “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.”
