Atta laevigata

Atta laevigata is one of about a dozen species of leafcutter ants in the genus Atta, found from Venezuela and south to Paraguay. This species is one of the largest leafcutter species, and can be recognized by the smooth and shining head of the largest workers in a colony. Atta laevigata is known in northern South America as hormiga culona, or as sikisapa in Peru, zompopo de mayo in Central America, bachaco culón in Venezuela, akango in Paraguay, and chicatana in Mexico. In Brazil they are known as "saúva-cabeça-de-vidro", with saúva being the common name for all Atta ants.
