caste - Of social insects, a type of structurally and functionally specialized individual. E.g. among hive bees there are three castes, queens (fertile females), workers (females, usually sterile), drones (males). Among ants there may be several different kinds of workers (all sterile females). In termites the distinction between castes is not related to sex (as it is in the bees and ants), e.g. 'soldiers' may be sterile males or females. See also: Polymorphism.
