Abstract

Polyethism, the divison of labor among members of a colony, is based on worker age and size in ants. In the ponerine species Amblyopone pallipes worker behavior is independent of age, therefore temporal castes, or groups of age-related task specialists, do not exist. This primitive caste system, previously unknown in ants, appears to be correlated with the peculiar characteristics of the life history and ecology of Amblyopone.
