Army ants are a group of aggressive, nomadic ants known for their large colonies and coordinated foraging behavior. They do not build permanent nests; instead, they create temporary shelters called bivouacs using their own bodies. These ants are famous for their ability to move in large swarms, overwhelming prey and scavenging for food. These ants are primarily found in tropical and subtropical regions, particularly in South America and Africa. They play a crucial role in their ecosystems by controlling pest populations and recycling nutrients. Their unique social structure and hunting strategies make them fascinating subjects for scientific research.
