Summary

Crabronidae is a large paraphyletic group of wasps that includes nearly all the species from the now-defunct superfamily Sphecoidea. It consists of over 200 genera containing more than 9000 species.

Diet

Larvae feed on prey captured and brought to the nest by adult wasps. The type of prey varies according to species of wasp, but includes aphids, bees, beetles, bugs, butterflies & moths, cicadas, cockroaches, crickets, flies, grasshoppers, hoppers, mantids, and spiders. Some species are kleptoparasitic.

Evolution

Crabronidae is a paraphyletic group; former superfamily Sphecoidea. The group includes several subfamilies often treated as separate families. Recent phylogenomic studies have shown that both bees and Sphecidae arose from within the Crabronidae.

Misconceptions

Crabronidae was formerly part of the Sphecidae, which is now recognized as a separate family.
