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.
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 ...
By the end of May, colonies in Australia have 15,000 wasps emerging from small cells and 2500 wasps emerging from the large cells. [5] By comparison, nests in the British Isles only have 6100–6500 small cells and 1500 large cells on average, in roughly eight combs. [ 6 ]

Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
Wasp season is typically between March and November but the bugs are especially active now after a mild winter and spring. “This is a really big year for wasps,” said Lynn Kimsey, director of ...
The Old Farmer's Almanac predicts that Oklahomans could keep wearing shorts and flip-flops for some time when fall begins, followed by "warmer than usual" weather through the 2024-2025 winter season.
In Polistes exclamans, equal sex ratio is obtained when only 46.3% of investment is devoted to females as female wasps are 1.16 times larger than male wasps. [16] In a study done by Strassmann, it was found that sexual investment is female biased, especially during years of high predation and when nests are generally less successful. [ 16 ]
