Acromyrmex fracticornis colony densities are positively correlated with basal grass coverage and the amount of grazing damage. A. fracticornis preferentially harvested tender grass blades that showed little or no previous damage by other invertebrates. They preferentially harvest Digitaria smutsii and Panicum maximum more often than other species, and Pennisetum purpureum, Pennisetum ciliare and Brachiaria decumbens were selected significantly less often.
