Silkworms, also known as "silkworms," are fascinating creatures that have been raised for centuries, especially in regions like Sichuan, Jiangsu, and Zhejiang. These small, gentle animals are not only economically important but also beloved by many, particularly children. In southern China, where mulberry trees are abundant, raising silkworms is a common family activity, offering both education and entertainment.
The silkworm larvae start off as tiny, black-haired creatures, growing up to about 50 mm in length as they mature. They are usually kept in small boxes or containers and fed with fresh, tender mulberry leaves. Initially, the young silkworms are given small amounts of finely shredded leaves, gradually increasing the quantity throughout the day—typically 3 to 4 times. It's important to clean their habitat regularly, removing any waste to keep them healthy.
After several molts, the silkworms lose their black fur and turn gray. By the fifth instar stage, they begin spinning cocoons. This process takes about 5–6 days, during which they stay in a quiet, undisturbed area. The cocoon can be white, yellow, green, or even a deeper shade depending on the variety. The entire feeding period lasts roughly 45 days, though this may vary based on temperature and conditions.
After about two weeks, the adult moth emerges from the cocoon. Once the male and female moths mate, the female lays eggs on paper. These eggs are collected and stored until the next spring, when the mulberry leaves begin to grow. As soon as the first leaves appear, the eggs are placed in a warm, moist environment. When the spring thunder sounds, the eggs hatch, and a new cycle begins.
Observing the life cycle of silkworms is both interesting and educational, especially for children. It teaches them about growth, transformation, and the natural world in a hands-on, engaging way. Raising silkworms is more than just a hobby—it's a connection to tradition, science, and nature.
