Retired Ant

Leaf-cutter ants have sharp mandibles that they use to cut leaves. As these insects age their mandibles wear down, using this dull cutting tool means it can take them three times as long to get the same piece of leaf. But these hard-working insects don’t exactly retire to the beach! Once a leaf-cutter ant’s mandibles are dull they take up a new role on the delivery crew where they carry the leaves back to the colony.
