In the nomadic phase the ants move their entire colony to a new location nearly every night for about two weeks on end.

[4] When the ants enter the statary phase, the queen's body swells massively and she lays as many as 80,000 eggs in less than a week.

[5] Because of the regularity and intensity of E. burchelli and E. hamatum swarms, many insect and bird species have evolved complex relationships with these ants.

Some of these birds actively check army-ant bivouacs each morning and follow the foraging trail to the swarm front, where they take positions based on their species' relations in a dominance hierarchy.

[6] The mite Trichocylliba crinita (Elzinga & Rettenmeyer, 1975) (Mesostigmata: Uropodidae) was found on the jaws of the species Eciton dulcium, and nowhere else.
