9. Leafcutter Ant
Leafcutter ants are different from other species of ants in the way they make their food. In fact, according to the Chicago-based Lincoln Park Zoo (LPZ), these ants are the first animals known to cultivate their own crops like farmers. They get their name because of their ability to cut leaves from trees with their scissor-like mandibles. Once leaves are cut, each ant carries a leaf back to the colony where the leaves are added to a pile, similar to a compost heap. Worker ants then add their feces or saliva to the leaves, which acts as a kind of fertilizer to help the leaves grow fungus. They later use the resulting fungus to feed ant larvae. While the baby ants eat the nutrient-rich fungus, adult ants feast on sap that’s also produced from the leaves.
