Ant Colonies and Their Structure

Ants are wonderful organisms which are found living in complex social colonies. And the term “ant colony” is more than just the physical habitat of ants. It also constitutes the different social rules by which ants organize themselves and the different works they find themselves doing. So if you want to know more about ant colonies and the structures they organize themselves in then keep on reading!

Different kinds of ants found in a colony

Whenever you come across ants they may strike you as disorderly. However, it’s actually the opposite. Ants form very orderly societies and colonies. Every ant in a colony has a function and a task they perform. And every ant also has its own place in the colony, which ensures that the colony is efficient and can flourish. Based on social organization, there are different types of ants in a colony:

Queen Ants

The queen ant in any ant colony is the founder and leader of the colony. Her main function is a reproduction of other ants. It has one of the most important roles in the colony. She stores sperm in a pouch in her abdomen and uses this sperm to fertilize her eggs and expand the colony. The queen’s chambers are located in the deepest parts of the colony to protect her against predators.

Queens are not only well-protected but also live longer than drones and worker ants. Some even live as long as 30 years. Queen ants usually have wings, which they remove after mating, and are larger in size than the average ant. They are usually the biggest ants in the entire colony. And, depending on the species of ants, a colony can have more than one queen.

Worker Ants

If the queen lays the eggs, then the workers do most of the jobs for the survival of the colony. Worker ants have different roles in their colonies. Some worker ants take care of the eggs that the queen lies. Workers are also responsible for cleaning the eggs and feeding the larvae and pupae stage ants. Worker ants that deal with reproduction never leave the nest.

Other worker ants leave the nest to locate food. And wherever they go they leave a chemical behind so they can find their way back to the mound. And then there are worker ants that build the nest.

Because as the ant population increases, they the size of the nest needs to be increased as well.

Majority of ants are female and it is quite uncommon to come across a male ant outside the nest. Worker ants are female ants that do not lay eggs. They are instead responsible for the construction, maintenance, and protection of the colony. Which is why worker ants are never idle and usually live for up to a year.


Drones are male ants whose main functions are mating with the queen. They die off upon completion of their duty and are rarely found outside the colony.


Sometimes the queen produces eggs that form winged male and female ants instead of regular worker ants. These winged ants are called alates. Upon maturity, their function is to leave their current colony and establish new ones. Just like drones, the male alates die after mating. While some female alates survive to become the queens of new ant colonies.

A lifespan of an ant colony

After an ant colony has been established, they can survive for a long time. Some even outlive their queens. The average lifespan of an ant colony differs based on which ant species we are referring to.

Carpenter ants and fire ants, for example, can have colonies that flourish for up to 5 and 7 years respectively. And the larger the ant mound is the more mature the colony is.

Average ant population in a colony

The average population of ants in a colony also dependents on the species ant. Fire ants and a few other ant species, for instance, can even form supercolonies. A supercolony is usually what you call a cooperative network of many ant mounds, queens and workers. Super colonies can extend for miles and house millions of ants.

While carpenter ants and other ant species usually form smaller colonies that support a single queen and do not cooperate with other ant nests.

This means that no matter what type of ant lives in your area, you can be sure that there is a nest nearby where hundreds more live. So when you go to get rid of the ants you have to make sure that you get rid of the whole colony, not just a few ants that you see out and about. Otherwise, your ant problem will persist.

Lastly, keep in mind that all ant mounds are well-defended because ants have ways of dealing with intruders. Some even go as far as sting their targets. Therefore, when you are gearing up for ant mount destruction you have to take this into account so you don’t get hurt while doing so.



Very professional and informative.


    Thank you, Johnina. Glad you found the article informative!


    Howdy folks, fun little article, just some points, workers are not set into one role, they just do whatever is required at the time. This means they do whatever pheremone task they detect. Ants will detect a task needing to be done, and they’ll leave a pheremone trail to cue other nearby workers to help out. Also there’s no leader in ant colony. Ants just do what’s required. They protect the queen and nest at all costs. In polygamous colonies, if a queen is sick, or if they’re is not enough food to go around for quite some time, they’ll cull a queen for the survival of the colony. It’s basically communism.


    Hi! Thanks a lot for the additional info!


Hi please can u use your as a reference for my research on ants


    Sure, go ahead. Good luck with your research!
