Silkworms are not actually worms at all. They are the caterpillars of a large white moth. Many moth caterpillars produce silk thread inside their bodies, but the thread of the silkworm is so fine and strong that human beings use it to make a beautiful fabric. In countries like Japan, people raise millions of silkworms on farms and take their thread to be processed into silk cloth. Readers of this book will find out how silk farmers process silk and what role this amazing thread plays in the life cycle of the silkworm moth.
