Leafcutter ants are fungus-growing ants that share the behaviour of cutting leaves which they carry back to their nests to farm fungus. Next to humans, leafcutter ants form some of the largest and most complex animal societies on Earth. In a few years, the central mound of their underground nests can grow to more than 30 m across, with smaller radiating mounds extending out to a radius of 80 m, taking up 30 to 600 m2 and occupied by 3.55 million individuals.
