The size of leaf fragments cut and carried by leaf-cutting ants affects the time and energy costs of providing substrate to the colony's fungal gardens. I estimate the costs and gains for individual workers of Atta colombica, a leaf-cutting species of South and Central American forest habitats. Load masses needed to maximize the rate or energetic efficiency of individual foraging are greater than average fragment masses actually carried by Atta colombica foragers in a lowland forest in Panama… Expand
