Leafcutter ants, as you can probably tell from the name, chop and chew leaves and other vegetation. The purpose of this behavior is to cultivate a white fungus in their nests. The ants grow these fungi in their nests to sustain themselves and their young.

An exhibition at the California Academy of Sciences in San Francisco will display how these resourceful agriculturalists transport and break down fresh foliage for their farming needs.

Check out this video from KQED about the practical farming and feeding habits of leafcutter ants.
