The diagrams illustrate the life stages of the silkworm and the process of producing silk fabrics.
Overall, silkworms remain in their cocoons for several days before transforming into moths and continuing the life cycle. Additionally, the silk industry primarily values the cocoons rather than the silkworms themselves. By harvesting the cocoons, people are able to create silk products, such as silk clothing.
Before silkworms metamorphose into moths, their lives heavily depend on mulberry leaves, which serve as both their food and habitat. After growing for 4 to 6 weeks, silkworms produce silk threads to construct their cocoons, where they will reside for the next 16 days. Following this period, they emerge as moths and lay eggs to initiate a new generation.
To make silk clothing, we first need to boil the cocoons and unwind them into threads that measure between 300 to 900 meters in length. Next, we twist the threads together and weave them into fabric. Finally, people can dye the fabric in any color they desire.
