BBC Four supersizes the insect world in an ambitious new season

Insect Worlds

In this three-part series of Insect Worlds, Steve Backshall explores the insects and their close relatives, the arachnids and crustaceans.

The series explores the intricate and at times bizarre relationships these animals have with humans, with our planet and with each other; Steve reveals how they play key roles in almost every intricate ecosystem that humans rely upon.

Using stunning behavioural sequences, these three programmes will reveal the relationships, dependencies, challenges and dramas that arthropods have developed throughout the world.

Insect Worlds is a joint commission by BBC Learning.

Insect Worlds (3x30) - 13, 20 and 27 March, 8:30-9pm
