An ant colony has several entrances (A) leading to a variety of subterranean chambers. Each chamber has a specific use. Some are for food storage (B). The queen has her own room (D). In another chamber workers tend unhatched eggs (C).

Ants are social insects which form small to large colonies. A typical colony contains an egg-laying queen and many adult workers together with their brood (eggs, larvae and pupae). Workers are by far the most numerous individuals in the nest.
