An ant, farming aphids

Ant Farmer

The other day we went for a walk in the countryside and while I was standing next to a rock looking at some flowers, I saw to my amazement an ant on the stem, and it was guiding the aphids, basically farming them like a shephard with its flock.

A quick read of Wikipedia tells me that the ants protect the aphids and milk them using their feelers, and when the aphids reproduce, the ants will take their eggs back to the ant hive and look after them, then carry the young aphids back to the plants to start the process again.
