The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines). Many species are pollen vectors contributing to the pollination of several plants, being potential or even effective pollinators, [ 2 ] while others are notable predators of pest ...
Paper wasp (Polistes major) nest (); exposed comb Paper wasp growth stages Yellowjacket nest (); concealed combPaper wasps are a type of vespid wasps.The term is typically used to refer to members of the vespid subfamily Polistinae, though it often colloquially includes members of the subfamilies Vespinae (hornets and yellowjackets) and Stenogastrinae, which also make nests out of paper.
It has been found that this specific nest odor is learned after wasps first emerge from the nest. Wasps are then able to use this scent for comparison to distinguish between members of their own colony and wasps from alien colonies. Members of the nest react aggressively towards alien wasps without the familiar, distinct odor that enter their nest.

Brachygastra mellifica make paper nests that range in size from 40–50 cm in diameter. These nests are quite full and can house anywhere from 3,500 to 18,700 wasps. [3] The nest begins as a single irregular layer of cells attached to the first layer of carton on a branch. Clumps of cells on the branch are then extended into the first hanging ...
Thanks largely to milder winters and a plentiful food supply, yellow jacket wasps are now building "super nests" in Alabama, according to the Alabama Cooperative Extension System.. Entomologists ...
Large paper nest, upside down pear shaped, hanging from branches and eaves; also barns and attics. Some yellowjacket species nest in the ground. Very large paper nest in hollow trees, sheltered positions. Has a brown, protective layer when the nest is in an unsheltered position. Also found in barns, attics, hollow walls and abandoned bee hives.
These nests are typically found in shrubs, trees, and sometimes under the eaves of buildings. [4] Nests are made of paper that comes from the digestion of wood and are generally 12–23 centimetres (4.7–9.1 in) wide and 10–30 centimetres (3.9–11.8 in) tall. [4] [12] Colonies are often found in both urban and rural areas. These wasps ...
