Based on the author's seventeen years of research on harvester ants in the Arizona desert, "Ants at Work" overturns all standard ideas of insect society hierarchy. Gordon shows that an ant colony operates without any central control and that no ant has power over another. Yet the ant colony, harmoniously performs extremely complex tasks; including nest building, navigation, foraging, food storage, tending the young, garbage collection, and on occasion, even war.

Ants also switch from one task to another, which undermines the standard view that insect societies are run on a caste system. G
