Atta (leafcutter ants)
Atta comprises the giant leaf-cutting ants of the new world tropics
and subtropics. These ants are farmers- they use freshly cut vegetation
to cultivate a fungus in subterranean gardens. Their leaf-cutting
habits make them one of the most economically damaging pest insects in
Central and South America. Colonies are among the most complex insect
societies known, and nests can persist for decades and contain over a million
individuals.
