Army ants in the genus Eciton, from Central and South America, and driver ants in the genus Dorylus, from Africa, have a reputation for travelling in highly organized columns. These can be up to 100 m (328 ft) long and over 1 m (3 ft 4 in) wide and may contain as many as 600,000 individuals which frequently take several hours to pass one spot.
