The Army Ant is the iconic swarm-raiding ant of the American tropics, forming massive bivouac colonies of hundreds of thousands of workers that march in broad raiding columns overwhelming all invertebrates and small vertebrates in their path. The colony is nomadic, with no permanent nest — instead, workers link their own bodies together to form living structures. Certain antbird species follow army ant swarms to catch flushed prey.
