North American ant species come in a wide range of sizes and colors(black, brown, red, yellowish and combinations of these).Ants communicate by touch and smell. They laydown chemical trails and constantly touch each other to on their nestodor.Ants are social insects and live in colonies which mayhave as many as 500,000 individualsTiny ants can lift objects that weigh more than they do Ants also have remarkably strong jaws and can give a painful nip. When species bite,they are able to squirt formic acid from the end of abdomen into the wound -making it doubly painful.When ants find food, they lay down a chemical trail,called a pheromone,so that other ants can find their way from the nest to the food source.
