Alloethism in the Carpenter Ant, Camponotus pennsylvanicus (Hymenoptera: Formicidae)
Fowler, Harold G
Worker size variation was examined with respect to task performance in the carpenter ant, Camponotus pennsylvanicus (De Geer 0000). Clear division of labor based on virgin female size was quantified for foraging related behaviors. Medium sized virgin females were found to be more responsive in colony defense, as well as to gnaw on the substrate, than either the smallest or largest virgin females. In relative terms, behavioral discretization based upon virgin female morphology was highly developed, with smaller virgin females being relatively more active than larger virgin females.
