Paper wasp nest with developing larvae

Nests occur under eaves, in sheltered wall cavities, garages, porches, and other protected structures. Paper wasps are common in temperate and subtropical regions.

Larvae eat masticated insects and spiders supplied by adult workers. Adults mainly consume nectar, fruit juices, and other sugary liquids.

Females build open-comb nests from chewed wood fibers mixed with saliva; the pictured nest appears to contain capped pupal cells and larvae. Colonies are seasonal, with new queens overwintering and founding nests in spring.

Adults can sting repeatedly when the nest is disturbed, posing a greater risk to allergic individuals. They benefit ecosystems by controlling caterpillars and other insect pests and by pollinating flowers.
