The Large Blue Butterfly, found in Europe, lays its eggs on a marsh gentian leaf. Its larva (a caterpillar) hatches and falls to the ground and emits a scent that smells to certain species of ant just like its own larvae. The ants carry the caterpillar back to their nest, where they not only care for it as one of their own, but as one of their own that is going to turn into a queen. Meanwhile, the caterpillar is eating the actual ant larvae and growing large.
