The Polistinae are eusocial wasps closely related to the more familiar yellowjackets, but placed in their own subfamily, containing four tribes; with some 1100 species total, it is the second most diverse subfamily within Vespidae, and while most species are tropical or subtropical, they include some of the most frequently-encountered large wasps in temperate regions. They are also known as paper wasps, which is a misleading term since other wasps (including yellowjackets) also build nests out of paper, and because some Epiponine wasps (e.g., Polybia emaciata) build theirs out of mud [1], nonetheless, the name paper wasp seems to apply mostly, but not exclusively, to the Polistinae, especially the Polistini. The brood cells are arranged in a hexagonal array, similar to the comb structure in a honey bee nest. At least one Epiponine species (Brachygastra mellifica) stores honey in the comb, one of the only insects other than bees to store honey.
Characteristics of Polistinae are:
Polistine wasps found colonies in one of two ways. In some species, nests are founded by a small number of reproductive females, possibly a single one. One of the foundresses eventually acquires dominance over the other and is the sole reproducer. The nest is open (not enclosed by an envelope) and contains a single comb.
In the other group, called swarm-founding, the nest is founded by a large number of workers and a few queens. It is usually protected by an envelope, like a vespine nest.
