The Secret to Their Success

Totaling an estimated 10 million species, the insects and their close relatives are the most abundant and diverse group of animals in the world. So, what is the secret to their success?

In Yellowstone National Park, Steve Backshall reveals how teamwork allows a colony of bees to scare off a hungry bear, and in Australia this same teamwork allows a colony of ants to beat the rising tide.

But to unlock the real secret to their success, Backshall takes us to the Swiss Alps, where an incredible relationship exists between the ant, the wasp and the butterfly.
