Ants have been around for about 100 million years and can be found in almost every land environment. They are social insects that live together in large groups or colonies. Most make their homes in underground tunnels and chambers. But some ants are different. Carpenter ants carve tunnels in wood (but don’t eat it). In the South American rain forest, many ants live in trees. And Army ants don’t build at all. They travel in big groups looking for food. Ants communicate by touching each other with their antennae. They show other ants where food is by making a path with a chemical called a “pheromone”. This leaves a scent for the other ants to follow. Each ant has a specific job. The queen lays eggs to populate the colony. Workers collect food, feed members of the colony, and enlarge the nest. Soldiers are large workers that defend the colony.
