The benefits are gained through various measures, such as increasing colony efficiency and establishing a female-based sex-allocation ratio. Worker policing is especially common in colonies where queens mate with multiple males. Thus on average, the workers are more closely related to sons of the queen than to those of other workers.
Interestingly, all the worker hornets die during winter while the fertilized females live. They hibernate in shelters until the temperature rises above 50 degrees. Mated queen hornets seek shelter ...

Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
