Ferocious Australian ants not only milk a certain caterpillar, but, like good farmers, guide it every night into a shelter they have prepared. Microscopic parasites ruthlessly exploit their hosts and beetle-like hangers-on perform beneficial cleaning services. Throughout the animal kingdom such relationships are widespread and vital to continued existence.
