Camponotus pennsylvanicus showed a diel foraging periodicity during summer, but patterns changed monthly. Predictive models of foraging intensity were generated through multiple linear regression incorporating environmental parameters. Smaller workers guarded aphid colonies, while larger foragers worked on the ground and in trees. Carbohydrate content of the various worker groups varied greatly. Average carbohydrate content of an individual ant was 52 μg for aphid guardians, 381 μg for tree foragers, and 485 μg for ground foragers. 13% of the forager force carried in excess of 1000 μg of carbohydrate, and probably serve to transport collected honeydew to the nest. Mark-recapture experiments indicated a high degree of task fidelity for those workers guarding aphids (x̄ = 86%) and those foraging on the ground (x̄ = 78%).
