Some soldier safari ants make tunnels to provide a safe route for the workers. Seasonally, when food supplies become short, they leave the hill and form marching columns of up to 20,000,000 ants, which constitute a considerable threat to humans, though they can be easily avoided as a column can only travel about 20 meters in an hour.
In South Africa, the Argentine ant has in some cases displaced native ants that disperse the seeds of Fynbos plants like Mimetes cucullatus. The Argentine ants don't take the seeds underground and are left on the surface, resulting in ungerminated plants and the dwindling of Fynbos seed reserves after veld fires. [48]
Leafcutter ants are any of at least 55 species [1] [2] [3] of leaf-chewing ants belonging to the three genera Atta, Acromyrmex, and Amoimyrmex, within the tribe Attini.

Vulture bees are reddish-brown in colour, featuring only a few lighter hairs on their thorax, and range in length from 8–22 millimetres (0.31–0.87 in). [1] As with many types of stingless bee, vulture bees have strong, powerful mandibles, which are used to tear off flesh.
Honeypot ants, also called honey ants, are ants which have specialized workers (repletes, [1] plerergates, or rotunds) that consume large amounts of food to the point that their abdomens swell enormously. Other ants then extract nourishment from them, through the process of trophallaxis. They function as living larders.
In some parts of the world (mainly Africa and South America), large ants, especially army ants, are used as surgical sutures. The wound is pressed together and ants are applied along it. The ant seizes the edges of the wound in its mandibles and locks in place. The body is then cut off and the head and mandibles remain in place to close the wound.
Tamandua is a genus of anteaters in the Myrmecophagidae family with two species: the southern tamandua (T. tetradactyla) and the northern tamandua (T. mexicana). [2] They live in forests and grasslands, are semiarboreal, and possess partially prehensile tails.
