The farmers of the insect world, leaf-cutter ants grow their own food in underground fungus farms. Pieces of leaf are carried hundreds of metres in impressive processions, with each ant carrying a piece up to 50 times its own body weight. That's like one of us carrying a medium-sized van. The leaves are used to create fungus gardens that feed the whole colony - millions and millions of ants. Soldiers protect the huge nest and the irreplaceable queen at all costs, as Sir David Attenborough discovered while delivering a piece to camera from the top of an ant nest for Trials of Life.

Super-organism
A fixed caste system turns millions of leaf-cutter ants into superbly efficient colonies.
Leaf-cutter ants are the major forest herbivores in Central America and consume more plant matter than all the vertebrate herbivores put together. Their subterranean nests can be vast and home to many millions of ants and they have a really neat defence system where minor workers ride shotgun on top of the leaf loads carried by the major workers and fend off the attacks of parasitic flies.' (George McGavin, on his love for leaf-cutters.)
Forest farmers
Leaf cutter ants harvest fresh forest leaves, for their fungal friends.
Leaf cutter ants make the most of the abundant supply of fresh leaves, collecting them in co-ordinated marches. Timelapse enhances the sense of ceaseless activity as they 'make hay' while the going is good, to maintain the food supply for the fungi on which they themselves then feed.
The Leaf-cutter ants can be found in a number of locations including: Amazon Rainforest, North America, South America. Find out more about these places and what else lives there.
The following habitats are found across the Leaf-cutter ants distribution range. Find out more about these environments, what it takes to live there and what else inhabits them.
