Silk is harvested from the cocoons of silkworms. For over 5,000 years it has been used to make magnificent textiles and luxurious gowns and accessories. But there is even more to this invaluable material than meets the eye. An avidly inquisitive textile designer, I turned the spotlight on the Bombyx mori, as it is called in Latin. With the aid of microphotography I examined the metamorphoses of larvae and moths and so brought to light their otherwise invisible features.
