Part 2/3. Life In The Undergrowth Ep. 2. From the stunning aerobatics of hoverflies in an English garden to the mass migration of purple crow butterflies in the valleys of Taiwan, this episode tells the tale of the first animals ever to take to the air. Unique footage reveals the lightning fast reactions of bluebottles and hoverflies, filmed with one of the world's fastest cameras, and David Attenborough handles the world's largest (and perhaps most ferocious) insect - the Titan beetle.
