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 ...
In entomology, overwintering is how an insect passes the winter season. Many insects overwinter as adults, pupae, or eggs. This can be done inside buildings, under tree bark, or beneath fallen leaves or other plant matter on the ground, among other places. All such overwintering sites shield the insect from adverse conditions associated with ...
To many “in-the-know” horticulturists, keeping dormant or dead plant material in place through the winter to help pollinators and beneficial insects is not new.
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 reproduction of gall wasps is usually partly parthenogenesis, in which a male is completely unnecessary, and partly two-sex propagation. [2] Most species have alternating generations, with one two-sex generation and one parthenogenic generation annually, whereas some species produce very few males and reproduce only by parthenogenesis, [2] possibly because of infection of the females ...
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 ]

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.
