Shape and size:
Paper wasp is the common name for medium – to large-sized wasps that construct nests made of a papery material. Most paper wasps measure about 2 cm (0.75-in) long and are black, brown, or reddish in color with yellow markings.
Signs of a Paper Wasp nest:
The nests are suspended from a single, central stalk and have the shape of an upside-down umbrella. Plant and wood fibers are collected by the wasps, mixed with saliva, and chewed into a paper-máché-like material that is formed into the thin cells of the nest. The nests are constructed in protected places, such as under the eaves of buildings or in dense vegetation. Normally a colony of several to several dozen paper wasps inhabit the nest.
