A close-up view of sex, bug-style, as David Attenborough talks viewers through the different ways in which creepy-crawlies reproduce. Size matters for the minuscule male orb spider, creepily sneaking up on its intended and trying to mate without her noticing, while there's no rest for the lothario-like butterfly, which has plenty of notches on its proverbial bedpost. However, the harvestman spider has no use for sex at all, and reproduces by cloning itself

David Attenborough shifts the focus to bugs that prefer co-operation rather than conflict. They include burrowing cockroaches, the suitably named social spiders - which share a 30-metre web - the queen bee and her happy hive of workers and green ants pulling together to build a nest

Documentary following David Attenborough as he journeys around the world to make his series First Life, which explores the origins of life on Earth. As he visits locations including the Great Barrier Reef, the deserts of Morocco and the glaciers of Canada, the broadcaster and wildlife expert explains his life-long fascination with the natural world, and also travels back to Leicestershire, the county in which he spent his childhood

Arguably more beautiful than butterflies, better fliers than hummingbirds and with intriguing and complex behavioural patterns - dragonflies and damselflies are marvels of the insect kingdom. This documentary uses the latest camera technology to show their manoeuvres, mating strategies, territorial behaviour and flight dynamics, revealing them to be the ultimate insect

The broadcaster explores the Galapagos, a collection of volcanic islands in the Pacific known for its extraordinary wildlife. More than 150 years after Charles Darwin formulated his ground-breaking theory of evolution on the remote archipelago, Attenborough explains how life on the islands has continued to evolve in biological isolation, examining how the ever-changing volcanic landscape has given birth to species and sub-species that exist nowhere else in the world. He begins by revealing how Galapagos rose from the ocean four million years ago

The natural world is filled with colourful, quaint and quirky characters. It may look crazy, but there are good reasons life got this way. This documentary reveals how, when the name of the game is survival, nothing is too outrageous
