Rainforest insects etc.
Army ants are meat-eaters, feeding on a variety of animals even including small birds.
They have huge pincerlike jaws. Army ants feed on anything in their path. Swarms of army ants move through the forest searching for food. As the swarm advances it disturbs insects which flee upwards, and the retreating insects are eaten by antbirds which accompany the ants as they make their way through the forest. Leaf cutter ants do not eat the leaves they clip, but instead carry them to an underground 'fungus garden' deep in the ants underground colony.
