Ants are social insects that typically live in underground colonies, made up of workers and a queen. Ants will eat practically any kind of food, but are especially attracted to sweets. Ants are easily identifiable due to their three distinct body region: head, thorax and abdomen, as well as antennae. Despite similar construction, ants vary in overall appearance. Small or large ants and brown or black ants are common nicknames for different species.
