David Attenborough reveals a secret universe it is teeming with life and is all around us, yet we never see it. It is the world of the very small, and it is a world of sex, drugs and violence. Here David shows us not just bugs, beetles and creepy-crawlies, but scorpions and centipedes, mites and mantids, spiders and dragonflies. And not just life in the undergrowth, but the dramatic battles between predator and prey that are happening in the corner of your living room and in your larder. See magnificent spectacles: swarming antler moths; millions of desert locusts; a mountain of locusts. For every pound of humans on Earth, there are 300 pounds of insects.
