Several human societies adopt nomadic lifestyles. From Yugurs on the Asian steppe to the Beja in northern Africa, these cultures traditionally gather food by tracking changing resources rather than relying solely on stable but geographically restricted food production. Not to be outdone by humans, some ants also exhibit nomadic behavior, most famously the army ants. But in 2008, Volker Witte and Ulrich Maschwitz reported an extraordinary and previously unknown behavior in ants: mushroom harvesting nomadism.
