The birth of an ant-fungus garden, with newly-laid ant eggs and the early stages of fungal growth. Leaf-cutting ant colonies subsist entirely on their cultivated fungus. (Acromyrmex versicolor)

Acromyrmex versicolor foundress queens in an incipient fungus garden. This species is normally polygynous during the colony founding stage, but reverts to single-queen colonies after the first workers emerge.

An Acromyrmex balzani worker carries a grass stem back to her nest. Leafcutter species tend to specialize on either broadleaf plants or grasses.

Entre Rios, Argentina

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.
