and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter. New queens and males (drones) are produced towards the end of the summer, and after mating, the queens hibernate over winter in cracks or other sheltered locations. 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

with the exception of a few communal and several subsocial species. The Stenogastrinae are facultatively eusocial, considering nests may have one or several adult females; in cases where the nest is shared by multiple females (typically, a mother and her daughters) there is reproductive division of labor and cooperative brood care. In the Polistinae and Vespinae, rather than consuming prey directly, prey are premasticated and fed to the larvae, which in return, produce a clear liquid (with high
