Silkworms, also known as "silkworms," are commonly raised in many regions across the country, particularly in Sichuan, Jiangsu, and Zhejiang. These creatures are not only important economic animals but also beloved pets, especially among children. In southern areas where mulberry trees are abundant, raising silkworms has become a traditional and educational activity.
The larvae of silkworms start off very small, just a few millimeters long, with dark bodies covered in fine black hair. They are usually kept in boxes and fed with tender young mulberry leaves. As they grow and molt several times, their dark fur gradually disappears, and their bodies turn gray. Freshly cut mulberry leaves should be provided 3 to 4 times daily, and it's important to clean up their droppings regularly to maintain hygiene.
After the fourth molt, they enter the fifth instar stage and begin spinning cocoons. This process takes about 5 to 6 days, and the cocoons can be white, yellow, or green in color. The entire feeding period typically lasts around 45 days, depending on the temperature. After about two weeks, the silkworms emerge from their cocoons as moths, mate, and the females lay eggs on paper.
In late April, when the mulberry leaves start to grow, the eggs are carefully removed. When the spring thunder sounds, the eggs hatch into new silkworms, starting a new cycle. Observing the life cycle of silkworms is both fascinating and educational for children and teenagers. It offers a hands-on way to learn about nature, growth, and the delicate balance of life.
