In this study, known-age workers of Agelaia pallipes (Olivier) were introduced into a colony maintained in the laboratory and the effects of age polyethism on the worker life span were observed. As in other Neotropical swarm-founding wasps, the results showed that younger workers remained on different places inside the nest performing activities related to the brood and nest maintenance, while risky tasks such as foraging were performed by older workers. Furthermore, the start of foraging activities had a significant effect on worker mortality.
