A Bug's Life (1998)

In every season, greedy grasshoppers demand a share of food from a colony of ants. But one day, their annual offering is inadvertently destroyed, and the grasshoppers demand twice as much food as compensation. So the ants send a misfit ant named Flik to seek for "warrior bugs" to battle the grasshoppers, only to discover that the group of bugs he recruited are an inept circus troupe. But the bugs are the ants' only hope to fight off their enemies.—MadMovieManiac
