Ants are social insects that are easily identified by their distinctive node-like bodies and elbowed antennae. There are currently about 3000 species of ants known to live in Australia. Generally they live in permanently nests, and colony sizes can vary enormously. They usually build their nests amongst rocks, or in soil or in wood. In relation to their feeding habits, ants may be scavengers, or predators, and can vary their diet to suit the available local food supply. As a group, ants are considered by many to be among the most successful of all insects. Because they are so commonly seen, ants are familiar to most people living in Australia. They can be commonly observed crawling along foundations and in walls, kitchens, roof voids, lawns and gardens, along rocks and in the wood of decaying trees.
