Did you know that humans weren’t the first to invent farming? About 12,000 years ago, we started growing crops and raising animals, but there’s another species that beat us to it by millions of years. It wasn’t another human-like creature; it was an insect: the ant! Specifically, leafcutter ants have been farming for about 55 million years.
You might have seen leafcutter ants in nature documentaries, busily carrying pieces of leaves in the rainforest. But what are they doing with those leaves? If you watch them closely, especially in an ant farm, you’ll see them building a complex colony. Unlike humans, they don’t grow corn or raise cows. Instead, they farm fungus!
Leafcutter ants, like the Atta cephalotes, are known for cutting leaves and taking them back to their colony. But here’s the twist: they don’t eat the leaves. Instead, they use them to grow their own food. This is a form of agriculture, which means farming to produce food.
The ants create special chambers underground to keep the temperature just right for their crops. They even bring water from the surface to keep things humid. The process involves drinking sap, cleaning the leaves, crushing them, and mixing them with their waste to create a perfect environment for the fungus to grow.
The fungus they grow is a type called basidiomycete. The ants carefully harvest parts of this fungus to feed their colony, much like how human farmers harvest crops. Over millions of years, these ants have evolved alongside their fungus, making sure it produces enough food for their entire colony.
Ants aren’t the only creatures that farm. Termites also grow fungi, and some fish, like damselfish, farm algae. Even certain beetles and snails have their own farming techniques!
Why is this important for us? Humans have been farming for a relatively short time, and we face challenges like soil depletion and crop diseases. We often rely on growing a single type of crop, which can be risky. But ants have been successfully managing their crops for millions of years. By studying their methods, we might discover new ways to farm sustainably and feed our growing population.
Aren’t ants fascinating? They are tiny but mighty farmers with a lot to teach us. If you’re curious to learn more about these incredible insects, we even have an interview with a bug scientist you can check out. What do you think about these mini farmers? Share your thoughts, and don’t forget to explore more amazing facts about nature!
Get creative and build a simple ant farm using a clear container, soil, and some leaves. Observe how ants behave and try to mimic their farming techniques. Document your observations and share them with the class.
Conduct an experiment to grow your own fungus using bread, water, and a sealed plastic bag. Compare your fungus-growing process to that of the leafcutter ants. Discuss what conditions helped your fungus grow best.
Participate in a classroom debate on the topic: “Who are better farmers, ants or humans?” Research both sides and present your arguments, focusing on sustainability and efficiency.
In groups, role-play as a colony of leafcutter ants. Assign roles such as leaf cutter, fungus farmer, and colony protector. Act out the process of collecting leaves and growing fungus, and discuss the importance of each role.
Choose another animal that practices farming, such as termites or damselfish. Research their farming methods and present your findings to the class. Compare their techniques to those of the leafcutter ants.
Here’s a sanitized version of the transcript:

Humans created farming around 12,000 years ago. However, there was another species that independently developed farming much earlier—about 55 million years before us. It wasn’t the Neanderthals or any apes; it was an insect: the ant. Specifically, leafcutter ants.
You may have seen clips in nature documentaries showcasing these fascinating creatures in the rainforest. In their natural habitat, it’s not immediately clear what they are doing. If you were to observe leafcutter ants in an ant farm, you would witness them building a colony. They don’t farm corn or livestock; instead, they cultivate fungus.
Leafcutter ants, such as the well-known Atta cephalotes, cut leaves and carry them back to their colony. But have you ever wondered what happens when they arrive? Surprisingly, the ants don’t consume the leaves directly. Instead, they use them to grow crops for their own agriculture.
Agriculture, by definition, is the science or practice of farming, which includes cultivating the soil for growing crops and rearing animals for food and other products. Ants are engaging in this practice! They dig growing chambers in deep tunnels to regulate temperature and transport dew and water from the surface to maintain humidity for their crops.
The Atta ants drink sap, clean the leaves, crush them, and compost them with their own waste. This process creates a nutrient-rich environment for the fungus (specifically a basidiomycete type) to thrive. The ants then harvest portions of the fungus to feed their colony, much like human farmers do.
While humans are relatively new to farming, with wheat being one of the oldest cultivated grains, it wasn’t until Norman Borlaug bred two special wheat varieties that we could feed millions of people. He was awarded the Nobel Peace Prize for this achievement in 1970. In comparison, ants have been practicing agriculture for millions of years, evolving alongside their crops, and even cultivating a fungal line that produces high yields to support their colonies.
Interestingly, some of the 250 species of ants that have developed agriculture have cultivated their crops to such an extent that the fungus would not survive without the ants.
Ants aren’t the only species that practice farming. Termites also cultivate fungi, and damselfish are known to farm algae. There are even beetle and snail species that engage in similar practices.
So, why should we care? Humans have only been farming for 12,000 years, and scientists are uncertain about the sustainability of our farming practices. With the need to feed billions of people, we often rely on monocultures—growing a single crop that can feed many, like Borlaug’s wheat. However, this method can deplete soil and make large crops vulnerable to disease.
In contrast, Atta ants and other fungal farmers have been successfully cultivating monocultures for millions of years. If we can learn from their methods of disease management and crop protection, we might find ways to support a growing human population sustainably.
