There are 39 different kinds of leaf cutter ants. Leaf cutter ants vary in color from reddish to dark brown, and can be up to a half an inch long.
What's really cool is that besides humans, leaf cutter ants make up the largest group of social animals on Earth! What's with the Name? Blackbirds are black and bluebirds are blue, right?

Well, leaf cutter ants cut leaves! Okay, so not the most creative name, but there's much more to it than that.
Leafcutter ant | insect tribe | socialgamenews.info
Leaf cutter ants spend almost all of their time cutting pieces of leaves and marching in lines to take them back to their underground nests.
They can carry leaf pieces that weigh up to three times more than them!
They sometimes carry them for over feet. That would be like you carrying your dad all the way across your yard! Sounds crazy, but these ants are incredible!
Leafcutter ants use chemical warfare to keep fungus at bay
So why all the Leaves? Leaf cutter ants cut mostly leaves, but they also cut flowers and grasses. They don't do it just to decorate their nests. Attini, leaf-cutter ant, parasol ant Leafcutter ant, tribe Attiniany of 39 ant species abundant in the American tropics, easily recognized by their foraging columns composed of hundreds or thousands of ants carrying small pieces of leaves.
These moving trails of cut foliage often stretch over 30 metres feet across the forest floor and up and down the trunks of canopy trees.
Leafcutter ants and many other ant species are common in tropical rainforests. After clipping out pieces of leaves with their jaws, the fragments are transported to an underground nest that can include over 1, chambers and house millions of individual ants.
The ants remove contaminants and produce amino acids and enzymes to aid fungal growth. They also secrete substances that suppress other fungal growth. Different ant species grow different fungi, but the fungi all belong to the family Lepiotaceae. In many instances, the cultivated fungi are members of either genus Leucoprinus or genus Leucoagaricus, which are commonly known as leucocoprinaceous fungi.
The cultivated fungi are found only in leafcutter nests, where they provide food for the ants in the form of the fungal strands themselves and as protein-containing bodies called gondylidia. While larvae depend on the fungus, workers also feed on plant sap. Among the Atta, new colonies are established at the beginning of the rainy season when queens carrying fungal fragments disperse in spectacular mating swarms.
In other genera, the pattern of fungus transmission is not clear. Leafcutters are the dominant herbivores of the New World tropics. The amount of vegetation cut from tropical forests by the Atta ants alone has been estimated at 12—17 percent of all leaf production.
