Paper wasps get their common name from the paper-like material out of which they make their nests. Paper wasps are sometimes called umbrella wasps, after the shape of their distinctive nests.
Paper wasps are semi-social and live in small colonies. They eat nectar and other insects including caterpillars and flies. In the autumn, inseminated females will seek places to spend the winter, and may find their way indoors, especially if there is a cathedral ceiling present.
Paper wasps hang their comb nests from twigs and branches of trees and shrubs, porch ceilings, the tops of window and doorframes, soffits, eaves, attic rafters, deck floor joists and railings, etc.
