Where Are the Ants Carrying All Those Leaves? | Deep Look

October 20, 2019


We’re looking at some of the world’s earliest
and most competent farmers. These leafcutter ants make humans look like
newbies. We’ve been farming for 12,000 years. Ants have been doing it for 60 million. We developed plows and shovels. Ants use their own bodies. Their mandibles
are shears that cut through leaves with incredible efficiency. The ants drink the sap in the leaves for energy.
But they don’t eat them. Remember, they’re farming here. They’re using the leaves to grow something else. But first they have to haul the gigantic leaf
pieces away. This is no small matter. For a human, it would be like carrying more than
600 pounds between our teeth. Then, they clean the leaves. They crush them. Cut them into little pieces. Arrange them carefully in stacks. They even compost the leaves, with a little
of their own poop. They spread spores around, like seeds. Over time, a fungus grows. And that – this highly nutritious fungus
– that’s what the ants are after. They feed it to the colony’s offspring, millions of them. For humans, farming was the origin of our
civilization. And it’s the same for ants. They are fungus tycoons. Their colonies are
true underground cities with a bottomless need for resources. Having this reliable source of food has given
them the luxury to specialize. Leafcutter ants have the most complex division of labor
of any ants. There are tiny worker ants. And large worker ants. And enormous half-inch-long
soldiers that protect the colony. Like human farmers, their abundant food source
has made leafcutter ants very, very successful. And this is where two civilizations – ant
and human – collide. From Texas to South America, leafcutter ants
are huge agricultural pests. Working stealthily at night, they can strip an entire tree of
its best leaves in just hours. As their ant civilization grows, they build
up the soil in the tropical forest. But they also pose a threat to those around them. And in this way, we resemble them more than we might like to admit.

    You forgot about one thing.
    The ants live underground and the fungus produce carbondioxide (CO2) as it grows, which can be deadly and suffocating to the ants. So how do they survive?

    I have two things to say. I’ve observed humans crushing insects so much, and it’s annoying to me. I watch someone I work with brutally murder over twenty crickets for no reason other than he didn’t like them. So that just shows you how sentient aliens could possibly perceive us. And the other thing is that I’ve eaten live ants before and they’re very tasty. It’s like eating a sour war head candy.

    Leafcutter ants, a non-generic name, are any of 47 species of leaf-chewing ants belonging to the two genera Atta and Acromyrmex. These species of tropical, fungus-growing ants are all endemic to South and Central America, Mexico and parts of the southern United States.
