Most ants are colonial, so they live in complex social groups with different castes (division of labour). When winter comes around most northern ant species will remain underground to avoid the extreme cold. Most can survive by allowing their tiny bodies to freeze, this is known as supercooling. While in this frozen state they are considered to be in what is known as diapause, a state similar to hibernation but with complete bodily and metabolic shutdown.
