An ant is a tiny insect that lives in organized groups called colonies, often with thousands or even millions of other ants. You've probably seen ants marching in lines across sidewalks or carrying crumbs many times their own size back to their nest.

Ants are remarkably strong for their size: they can carry objects 10 to 50 times heavier than themselves. Imagine if you could pick up a car as easily as an ant picks up a bread crumb! They work together with incredible coordination, following scent trails left by other ants to find food and bring it home. Each ant has a specific job: some gather food, some defend the colony, some care for baby ants, and one special ant, the queen, lays the eggs.

When scientists study how ants cooperate without any single ant being in charge (except for reproduction), they learn valuable lessons about teamwork and problem-solving. Ant colonies can build elaborate underground cities with different chambers for storing food, raising young, and disposing of waste. Some ants even farm fungus for food or keep other insects like aphids as “livestock.”

The phrase ants in your pants describes someone who can't sit still, fidgeting and moving constantly, like they have ants crawling on them.
