QUOTE : Over one hundred ninety species of ants have been found to grow a kind of fungi which they fertilize, plant, and even prune. Many of them also keep aphids the way we keep cows. They milk them to obtain their sweet honeydew and build shelters for them like barns. One kind of ant, the fierce Amazon, goes so far as to steal the larvae of other ants to keep as slaves. These slave ants build homes for and feed the Amazon ants, who are unable to do anything but fight. The soldier ants depend completely on the slave ants for survival. Without them, they would die.
