Summary

Masarinae, or pollen wasps, are a unique subfamily of wasps known for their larval diet of pollen and nectar, reminiscent of solitary bees. They construct nests from mud or sand and are particularly diverse in desert ecosystems.

Physical Characteristics

Typically black or brown with contrasting patterns of yellow, white, or red. Antennae are distinctively clubbed; males have elongated antennae ending in a strong club.

Identification Tips

Look for clubbed antennae and two submarginal cells in the forewings. Species may resemble yellow jackets but can be identified by their distinctive antennae.

Habitat

Desert regions of southern Africa, as well as deserts in North and South America; nests are often found under rocks or in crevices.

Distribution

Worldwide; particularly diverse and abundant in desert areas.

Diet

Larvae feed exclusively on pollen and nectar which adults collect and store in their nests.

Life Cycle

Eggs are laid in a mixture of regurgitated pollen and nectar, which serves as provisions for the larvae. After hatching, larvae consume these provisions, pupate, and emerge as adults.

Reproduction

Females build nests, provision them with pollen and nectar, and lay eggs in the food mixture.

Ecosystem Role

Pollinators in their ecosystems; their larvae feed on pollen, influencing plant reproduction.

Evolution

Historically recognized as a separate family, Masaridae, which included other subfamilies; currently classified under Vespidae.
