Ant War

War between social insects, usually ants against other ants. Though it takes place on a much smaller scale than human warfare, the insects will be regimented like human soldiers and use tactics familiar to humans. This familiar association makes political allegory all but inevitable.

Not to be confused with Bug War.

Anime and Manga

 * In the Helen ESP chapter "Helen And The Dream",

Film - Animated

 * The Dueling Movies Antz and A Bugs Life both had such wars -- in the former, between ants and termites, in the latter, between ants and marching locusts (who were called 'grasshoppers').

Literature

 * Terry Pratchett once depicted War (the horseman) watching a battle between red and black ants.
 * In The Once and Future King, one of the animal transformations Merlyn performs on Wart is to turn him into an ant, and he finds himself in the middle of an ant war.
 * Bernard Werber's Empire of the Ants, especially the first book.
 * George R. R. Martin wrote "Sandkings," a short story about a species of warring, antlike creatures sold as pets. It doesn't end well.
 * Professor Mmaas Lecture makes references to frequent termite-ant wars.
 * Done in Animorphs including one intentionally started war to get attacking ants off an unconscious Rachel.

Mythology

 * In a very old example of an Unbuilt Trope, Greek Mythology, the soldiers Achilles commands in the The Iliad are called the Myrmidons, or, in Greek, "ant-people." This name came from their origin as ants turned into warriors by Zeus in answer to a king's prayer to repopulate his country after a plague. The word "myrmidon" has come to denote any mindless group of subordinates, and is essentially the source of the allegory on which this trope is based.

Real Life

 * Yes, ants really do have wars. Truth in Television.

Theatre

 * The third act of The Insect Play by the brothers Čapek features two nations of ants (explicitly compared to human society) going to war over a path between two blades of grass, each fighting to exterminate the other.

Video Games

 * Paper Mario the Thousand Year Door: The Punis aren't exactly insects, but their war with the "rival tribe" of mosquito like Buzzis plays out as this trope.
 * Happens (perhaps without the metaphor) in Sim Ant, naturally.
 * Battle Bugs is a Real Time Strategy all about such a war.

Western Animation

 * In the Merrie Melodies cartoon "The Fighting 69½th", red ants and black ants go to war over picnic food.
 * One episode of the Jumanji animated series featured a war between giant red ants and black ants started by a rather stupid reason.
