Leafcutting ants (Atta and Acromyrmex) sometimes form piles or caches of leaves on foraging trails. Laboratory experiments have shown that leaf caching at the nest entrance by Atta cephalotes and Atta colombica is adaptive because it occurs when a colony's leaf delivery rate exceeds its leaf-processing rate and serves to increase the probability that a dropped leaf is eventually recovered. We examined the occurrence and adaptive value of leaf caching on foraging trails in field colonies of A… Expand
