Texas Leaf Cutting Ant

Leaf cutting ants live in large colonies of up to two million. The name comes from their habit of cutting leaves and other plant parts from a variety of plants. In Texas, these ants damage weeds, grasses, plum and peach trees, blackberry bushes and many other fruit, nut and ornamental plants as well as several cereal and forage crops. The ants do not eat the leaf fragments they collect, but take them into their underground nest where they use the material to raise a fungus garden. As the fungus grows, certain parts of it are eaten by the ants and fed to the larvae. This fungus is their only known source of food.
