Pollen wasps are unusual wasps that are typically treated as a subfamily of Vespidae, but have in the past sometimes been recognized as a separate family, "Masaridae", which also included the subfamily Euparagiinae. It is a small subfamily, unique among wasps in feeding their larvae exclusively with pollen and nectar, in a fashion quite similar to many solitary bees. Most species are black or brown, marked with strikingly contrasting patterns of yellow, white, or red (or combinations thereof). They are most diverse and abundant in the desert regions of southern Africa, but also occur in the deserts of North and South America. Some species of Pseudomasaris in California, such as Pseudomasaris vespoides, bear a remarkable resemblance to yellowjackets, but can be recognized by their strongly clubbed antennae, a characteristic feature of the subfamily. Males have the antennae greatly elongated, but still ending in a strong club.
