Leafcutter ants are any of at least 55 species [1] [2] [3] of leaf-chewing ants belonging to the three genera Atta, Acromyrmex, and Amoimyrmex, within the tribe Attini. [4] These species of tropical, fungus-growing ants are all endemic to South and Central America, Mexico, and parts of the southern United States. [5]

Atta is a genus of New World ants of the subfamily Myrmicinae.It contains at least 17 known species. Atta leafcutter ants are relatively large, rusty red or brown in colour, and have a spiny body and long legs.
Leafcutter ants live only in South America, Mexico, Central America, and a few select areas of the Southern United States, including Texas.. There are at least 55 distinct species of leaf cutter ...
Atta cephalotes is a species of leafcutter ant in the tribe Attini (the fungus-growing ants). A single colony of ants can contain up to 5 million members, and each colony has one 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. [2]
There are five main types of agriculture that fungus-growing ants practice: [9] Lower, coral fungi, yeast, generalized higher, and leafcutter agricultural systems.Lower agriculture is the most primitive system and is currently practiced by 80 species in 10 genera.
New research shows that ants have been farming fungi for 66 million years — thanks in part to the asteroid that fueled the demise of the dinosaurs.
Acromyrmex versicolor use trails to forage in groups like most higher attines, but also forage alone which is a characteristic of more primitive leafcutter ants. [9] They forage for both green vegetation and dry grasses, but dry grasses make up the bulk of their forage.
