Euparagia desertorum
Euparagia desertorum is a species of pollen wasp in the subfamily Masarinae, described by Bohart in 1948. The species epithet "desertorum" suggests an association with desert habitats. Members of the genus Euparagia are among the most primitive living vespid wasps and are endemic to arid regions of western North America. Like other masarine wasps, adults are solitary and provision their nests with pollen and nectar rather than prey.
