Acromyrmex
is the more diverse of the two leafcutting ant genera (the other is Atta). These distinctive spiny insects cut fresh vegetation to feed to a specialized fungus that grows only in ant nests. The fungus serves as the ants' food source and in return is cultivated and dispersed by the ants. Like all fungus-growing ants, Acromyrmex is found only in the new world tropics and subtropics.
An Acromyrmex echinatior leafcutter worker displays a microbial white patch on her underside made of Actinomyces bacteria. The bacteria are thought to produce antibiotics protecting the ants' fungus garden from infection- a true example of pesticide use among agricultural insects.
