Sterile worker wasps assist in building the nest, feeding young and defending the nest. A mature paper wasp nest may have 20 to 30 adults. In late summer, queens stop laying eggs and the colony soon begins to decline. In the fall, mated female offspring of the queen seek overwintering sites. The remainder of the colony does not survive the winter.
Mouthparts are for chewing.
Nests are built from wood fiber collected from posts and occasionally from live plant stems, causing some plant damage. This fiber is chewed and formed into a single paper-like comb of hexagonal cells. Nests are oriented downward and are suspended by a single filament. Mature nests contain up to 200 cells. Paper wasps prey on insects such as caterpillars, flies and beetle larvae which they feed to larvae.
