Since the nests are single combs fixed to a substrate by a peduncle, the suspended cells are often protected from attack by ants. [6] If there is an ant attack, nest abandonment is easier and allows for a more rapid escape due to the fact that the wasps do not build envelopes over their nests.
Polistes is a cosmopolitan genus of paper wasps and the only genus in the tribe Polistini. Vernacular names for the genus include umbrella wasps, coined by Walter Ebeling in 1975 to distinguish it from other types of paper wasp, in reference to the form of their nests, [3] and umbrella paper wasps.

All species of social wasps construct their nests using some form of plant fiber (mostly wood pulp) as the primary material, though this can be supplemented with mud, plant secretions (e.g., resin), and secretions from the wasps themselves; multiple fibrous brood cells are constructed, arranged in a honeycombed pattern, and often surrounded by ...
Here’s how to identify yellowjackets and other wasps, avoid them and what to do if you see one near your home. Several wasps build a nest to lay their eggs. Hot weather could increase the number ...
Polistes annularis (P. annularis) is a species of paper wasp found throughout the eastern half of the United States. [1] [2] This species of red paper wasp is known for its large size and its red-and-black coloration and is variably referred to as a ringed paper wasp or jack Spaniard wasp.
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.
Since P. carolina nests in sheltered areas, it commonly constructs nests in close proximity to humans, such as the open space under a roof. Typically, paper wasps are relatively unaggressive, only attacking humans and animals if they or their nests are being threatened. As in other aculeate wasps, only females have the ability to sting.
