Temporal Polyethism and Life Expectancy of Workers in the Eusocial Wasp Polistes canadensis canadensis Linnaeus (Hymenoptera: Vespidae)

The division of tasks among nestmates is one of the most important traits of the social Hymenoptera, and is responsible for their evolutionary success. This division of labor, which occurs among workers throughout their lives, is called temporal polyethism. This study investigated how temporal polye...
