Human societies may be divided into six classes or stages the hunting, pastoral, agricultural, commercail, industrial and intellectual ; and ants have stages corresponding to the first three. Some ants live solely by the products of the chase ; they are known as the driver and legionary ants. Some keep domestic animals. in the shape of plant lice, small insects, and caterpillars ; these belong to pastoral class. the agricultural class is represented by the harvesting ants, which collect, store and it is said,plant seeds. Against these resemblances may be set in the fact that ant societies are almost solely composed of females, for the males take little part in the social life of the colony
