One of the most common insects is the ant with over 12500 varieties around the world. They are social creatures living in structured colonies of a few dozens to thousands within each hill or mound. The queen or queens are the only productive females in the colony. The prolific males are known as drones. The remaining ants are infertile and are the workers or soldiers of the colony. The only places that do not have ants are extremely cold such as Antarctica, Greenland and Iceland, and there are some areas in Polynesia and the Hawaiian Islands with no native ants. Ants make their homes in a number of habitats some like living in wood or other natural habitation such as acorn's tree limbs, or beneath the earth. Most ants are dark or black with a few rare exceptions that are green or yellow.
The life span of an ant varies, the queen often lives as many as thirty years; however, the workers only survive one to three years. Males of the species have a much shorter life span of a few weeks. They eat a wide range of foods, which includes other insects, dead animals, seeds, fungus, that is grown within their own colony, and nectar.
