About the Hairy-Headed Leafcutter Ant
Atta cephalotes, commonly known as the hairy-headed leafcutter ant, is a species of leafcutter ant in the tribe Attini (fungus-growing ants). A colony can contain up to 5 million members, and each colony has a single queen that can live more than 20 years. The colony comprises different castes, known as "task partitioning", and each caste has a different job to do. This caste system includes minims, medias and majors.
The species is one of the earliest formally classified ants, first described by Swedish zoologist Carl Linnaeus in 1758. It was originally described as Formica cephalotes in his book the 10th edition of Systema Naturae, along with 16 other ant species, all placed within the genus Formica. It was later transferred to a new genus, Atta, along with five other species by Danish zoologist Johan Christian Fabricius in 1804. In 1911, American entomologist William Morton Wheeler designated A. cephalotes as the type species of Atta. It was also designated as the type species of Oecodoma, but the genus is now a synonym of Atta.
The elder workers manage the colony's rubbish dump. These ants are excluded from the rest of the colony. If... Wikipedia →
