Atta Ant ハキリアリ
One day a boy in Louisiana woke up to find that all the leaves on a tree in his backyard had disappeared;
only a few threads of the leaves were left.
He knew what had happened. A new colony of Atta ants had come to his neighborhood.
A farmer in Texas said that a heavy bag of seeds for his chickens was emptied by a single colony of Atta ants in one night.
Atta ants aren't very big, but they can carry heavy things, and there are many thousands of them, sometimes millions, in a colony.
In one night, they can make the leaves of a tree or the plants in a garden disappear.
With their scissor-like jaws, they spend hours cutting off pieces of leaf to carry back to their nests.
They don't eat these leaves, so why do they carry pieces of leaf many times their own weight far away to their nests?
It's because they eat only one kind of food - a special fungus that they grow on the leaves.
They are the only creatures who can make this special fungus grow properly.
You already know that a fungus is a decomposer.
It grows on dead leaves and other dead matter.
Did you know that some funguses are good to eat?
If you have ever eaten a mushroom from the grocery, you have eaten a piece of fungus.
Did you like the taste?
Be careful about eating any of the mushrooms growing in the forest, because many are harmful to humans!
The Atta ants take their leaves to a cave they have dug deep underground.
Some of their caves are as deep as twenty feet!
There in their nests they have their fungus farms.
On each piece of leaf in their nest, they carefully place a tiny bit of the fungus.
And it starts to grow on the leaf.
In a few days the leaf will be covered with white fungus.
After a while the fungus makes little knobs of delicious food that the ants eat.
To grow their crop, the Atta ants must work hard to keep the conditions just right for their special fungus.
The air must not be too dry or too damp.
If it is too dry, the ants close the opening to the nest.
If the air is too damp, they open up holes to let the air in and out.
They must also keep the crop perfectly clean by taking away any foreign fungus that might start infecting the food.
Hundreds of Atta ants spend all of their time just cleaning the fungus farm, like farmers removing weeds, so only the right kind of crop will grow there.
The Atta ants are just one of the fascinating members of the ant family.
Others, like the carpenter ants and the *honeydew ants, are just as interesting.
If you want to find out more about ants, ask for good books about them in the library.
