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.
Acromyrmex sp. nr. crassispinus cutting into an orange peel. Citrus is a favorite target for leafcutters, perhaps because the plants are not native to the Americas and have not yet evolved defenses against the voracious ants.
