About this image

Scanning electron micrograph of silk fibres. Silk is the fibre spun by the larva of the domesticated silkmoth (Bombyx mori). During pupation the larva makes a protective cocoon of these fibres, comprising two strands of fibroin cemented together with gum-like sericin. Each fibre may be up to 900 metres long. This image was captured in monochrome then later digitally colourised. PS Micrographs, Powys, United Kingdom
