Polymorphism and foraging behavior in Pogonomyrmex badius (Hymenoptera: Formicidae): worker size, foraging distance, and load size associations

The relationship between caste polymorphism and foraging strategy was examined in the Florida harvester ant, Pogonomyrmex badius (Latreille). Foragers of P. badius were offered two sizes of barley seed (4 or 33 mg) at 1, 2, 5, and 10 m from the nest entrance. No consistently significant correlations...
