Colonies of army ants are large compared to the colonies of other Formicidae. Colonies can have over 15 million workers and can transport 3000 prey (items) per hour during the raid period. [14] [20] When army ants forage, the trails that are formed can be over 20 m (66 ft) wide and over 100 m (330 ft) long. [20]
The ants can detect the pheromones with their antennae and can tell the difference in concentration gradients of the pheromones as they move away from the center of the trail. Also, individuals who are outbound, turn to avoid the inbound ants more frequently, giving the prey-burdened ants the right-of-way on the trail. [16]
Eciton army ants have a bi-phasic lifestyle in which they alternate between a nomadic phase and a statary phase. In the statary phase, which lasts about three weeks, the ants remain in the same location every night. They arrange their own living bodies into a nest, protecting the queen and her eggs in the middle.

Aenictogiton or army ants never forage or hunt alone, they instead use leaderless, co-operative mass of ants to overwhelm their prey all at once.

Dorylus laevigatus is a member of the army ant genus Dorylus, or Old World army ants.More specifically known as "driver ants", the genus Dorylus is abundant throughout Africa and stretches into tropical Asia, where D. laevigatus is primarily found.
The unique "sound" of the ants devouring everything in their path was created by swirling a straw in a glass of water with crushed ice, which was then amplified. Much of the Rio Negro (Amazon) jungle riverscape, as well as the bridge dynamiting and sluice scenes, are second-unit stock footage shot in Florahome, Florida .
Dorylus, also known as driver ants, safari ants, or siafu, is a large genus of army ants found primarily in central and east Africa, although the range also extends to southern Africa and tropical Asia.
