The pictures show how the ailanthus silkmoth and the red admiral spin silk and weave a cocoon, and the way in which the change from caterpillar to moth is affected.

Beneath the waves are mountains, plains and valleys full of life: here the conger, the octopus, and the wrasse hunt for food; shrimps and prawns act as scavengers; sea anemones and starfish decorate the seafloor, and the spider crab assumes protective colouring by covering its back with pebbles.

A sign of approaching winter - the frost catches the leaves which begin to fall.

These pictures show the marvellous industry of the Bee, the ingenuity it exercises in making its home, and the ordered programme of life that it appears to follow.

Austerity-stricken wartime viewers can learn from their economical feeding habits. An entertaining hybrid of public information and natural history from the makers of wildlife series Secrets of Life. Released in the BFI boxset Ration Books and Rabbit Pies: Films from the Home Front.

A meditative, immersive tribute to the astonishing work and achievements of naturalist, inventor and pioneering filmmaker F. Percy Smith. Smith worked in the early years of the 20th century, developing various cinematographic and micro-photographic techniques to capture nature's secrets in action. Working in a number of public roles, including the Royal Navy and British Instructional Films, Smith was prolific and driven, often directing several films simultaneously, apparently on a mission to explore and capture nature's hidden terrains. This film is an interpretative edit that combines Smith's original footage with a new contemporary score by tindersticks to create a hypnotic, alien yet familiar dreamscape that connects us to the sense of wonder Smith must have felt as he peered through his own lenses and seen these micro-worlds for the first time.

This peek behind the scenes at Kew Gardens in the 1940s was part of the ever-eccentric Secrets of Life series. Arcadian images of tranquil greenery, attended to by a discreet army of gardeners, make it hard to believe WWII was raging in the background. We're also treated to a spot of the series’ trademark time-lapse nature photography and charming narration - one plant described as "rather like an Italian having an argument with his hands".

A short documentary study of hops, barley and yeast, and how they interact.

The film shows speeded-up germination of the seed to form roots and shoot, at whose base the leaves later form a bulb. The flower produces pollen grains (shown much magnified), which are transferred by insects to the stigmas for fertilization of seeds inside the ovary.
