We domesticated cows six thousand years ago, but these tiny farm animals have been kept for far longer.
As the aphid sucks sap they create sugary produce for their equally diminutive farmers. The ants milk their hairs by stroking them with their antennae. The sweet secretion is known as honey dew.
Like human farmers the ants even move their live stock to richer pastures to increase production.
They also protect their herds. On this scale a lady bug is more dangerous than a wolf. But if these mini herdsmen work together the castle raider hasn’t a chance.
