"army ant"の定義と意味

What is an "army ant"?

An army ant is a formidable and highly organized insect known for its large-scale group movements and aggressive behavior. These ants travel in massive swarms, devouring everything in their path, including other insects, small animals, and even plants. With their powerful mandibles and coordinated attacks, they overwhelm their prey and strip the surrounding area of resources. Despite their nomadic lifestyle, army ants play a crucial role in their ecosystems by controlling pest populations and redistributing nutrients.
