The biggest feature is the division of labor among members according to hierarchical differentiation. Because the ability of ordinary animals to maintain individuals and races is shared among different levels, the whole cluster has super-individual behavior, and it is difficult for individual members to survive without the cluster. In addition, there is a view that in order to realize real social life, females of the same generation live in groups and nest together (community behavior) and achieve the goal of different generations through similar social behavior and hierarchical semi-social behavior of rearing larvae. The quasi-sociality of social behavior is different from the sub-social system (C.D.Mitechener) in which a female insect stays in the nest to take care of her offspring. The long-term hierarchical generation of female bees (ants) constantly nurtures the next generation to realize social life.
