Pepsini
Tarantula-hawk Wasps and Allies
Pepsini is a tribe of spider wasps within the family Pompilidae, comprising approximately 11 genera and at least 40 described species. The tribe includes the well-known genus *Pepsis*, commonly called tarantula hawks, which are among the largest spider wasps. Members of Pepsini are specialized predators that hunt spiders as hosts for their offspring. The tribe has undergone taxonomic revision, with several genera transferred to the separate tribes Deuterageniini and Priocnemini.

tarantula hawks, New World Tarantula-hawk Wasps
Pepsis is a genus of large spider wasps in the family Pompilidae, commonly known as tarantula hawks. These wasps are among the largest stinging insects in the world and are restricted to the Americas. Females hunt tarantulas and other large mygalomorph spiders, paralyzing them with a sting to serve as living food for their larvae. Adults feed primarily on nectar, especially from milkweed flowers. The genus is closely related to Hemipepsis, which occurs in both Old and New Worlds.
