Leafcutter Ants, Atta sp.
Chan Chich, Gallon Jug
Leafcutter ants send streams of workers into the forest to cut and harvest leaves (and, as here, flowers) that are brought back to the colony. The leaves are not eaten, however, and instead are used to grow fungi which are the ants' actual food. The colonies can be enormous, containing up to 10 million individuals.
(Order Hymenoptera, Family Formicidae)
