Atta cephalotes

Wells et al. (2017) - Forms large colonies with millions of workers and nests that can cover more than 100 square meters (Weber 1982, Meyer et al. 2011). In secondary forests and at forest edges, they can reach very high densities and are often the dominant herbivore in the ecosystem (Farji-Brener and Illes 2000). While they are also present in primary forests, their colonies are most common in secondary or disturbed forests (Farji-Brener 2001). The large nests of Atta cephalotes have a strong effect on the leaf-litter arthropod community, adding to spatial heterogeneity within neotropical habitats.
