Mischocyttarus is a very large, primarily Neotropical genus of social wasps with a few species found also in the Nearctic region. It is the only member of the tribe Mischocyttarini. Mischocyttarus wasps build a relatively simple, single comb nest. Sometimes, the nest is built within a meter of the nest of Polistes carnifex.[1] It can be distinguished by its brown and yellow stripes.[1] [2] Foraging adults bring nectar and small caterpillars back to the nest to feed to the developing larvae which are individually housed in separate cells in the nest.[3] Not all nests have a female with developed ovaries.[1] Their biology is similar to that of species in the genus Polistes. However, Mischocyttarus appear to show considerably more social and reproductive flexibility than Polistes.
