In brief
Ants are small social insects of the family Formicidae, found almost everywhere on Earth except the far polar regions. Ranging from 1 to 13 mm depending on species, they live in highly organised colonies of dozens to millions of individuals, each with a queen, workers, and cooperative roles.

Ants are small social insects of the family Formicidae, found almost everywhere on Earth except the far polar regions. Ranging from 1 to 13 mm depending on species, they live in highly organised colonies of dozens to millions of individuals, each with a queen, workers, and cooperative roles. Famous for their strength and teamwork, ants can lift many times their own body weight and are one of the most successful animal groups on the planet.

Key Facts: Ant
- Ants are among the most social of all insects, living in colonies built around a strict division of labour.
- For their size, ants are astonishingly strong, and many species can carry objects many times their own body weight in their jaws.
- Ants rely heavily on chemical signals called pheromones to coordinate their colony.
Colony life and castes
Ants are among the most social of all insects, living in colonies built around a strict division of labour. A colony centres on one or more egg-laying queens, supported by large numbers of sterile female workers who forage, build, and care for the young. Males exist mainly to mate, and a single colony can range from just a few dozen ants to several million. This teamwork lets a colony behave almost like a single organism.
Strength and teamwork
For their size, ants are astonishingly strong, and many species can carry objects many times their own body weight in their jaws. By working together, columns of ants can move loads and overcome obstacles far beyond the ability of any individual. Some species even link their bodies together to form living bridges and rafts, allowing the colony to cross gaps and floods.
Communication with scent
Ants rely heavily on chemical signals called pheromones to coordinate their colony. A forager that finds food lays a scent trail on the way home, and nestmates follow and reinforce it, which is why ants so often march in orderly lines. They also use touch and antenna-tapping to share information, and different scents can raise an alarm or identify intruders from another colony.
Diet and foraging
Most ants are omnivores whose exact diet varies widely by species. Many feed on seeds, nectar, and the sugary honeydew produced by aphids, which some ants tend and protect like livestock. Others are hunters that scavenge or capture insects and small invertebrates. Leafcutter ants take a different path, harvesting leaves to grow an underground fungus that the colony then eats.
Lifespan and the colony cycle
Lifespan varies enormously across the caste system. Worker ants may live only weeks to about a year, while a queen can survive for 15 years or more, laying eggs throughout her long life. New colonies begin when winged males and young queens leave the nest in a mating flight; after mating, a founding queen sheds her wings and starts a new colony largely on her own.
Diversity and success
There are more than 12,000 known ant species, occupying nearly every land habitat from tropical rainforest to city pavements, and absent only from the coldest polar regions. This diversity, combined with their social organisation, makes ants one of the most successful groups of animals on Earth. As a group they are common and listed as Least Concern by the IUCN, though some individual species are far rarer.
What WARN Does
WARN does not run a dedicated ant programme — this guide is part of the World Animal Rescue Network's free educational library. The ant is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the ant supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.
If clear, science-based wildlife guides like this help you understand and value animals, please consider supporting the World Animal Rescue Network's educational and rescue work so we can keep producing them.
