It is necessary to put something that can be supported in the silkworm rearing box to help cocoon formation, such as some dry branches and hay branches. In the absence of anything to support, the silkworm baby can't spin silk, so it won't cocoon, and finally it will only suffocate and die. Mature silkworms spit out the silk first, then stick it on the cocoon catcher, and then connect the surrounding brackets with the silk to gradually form a cocoon net. The cocoon net has no cocoon shape, just some soft and messy cocoon silk layers as the support for cocoon formation.

Precautions:
1. Silkworms are particularly sensitive to fragrance, and cannot use perfume, mosquito-repellent incense, air purifiers, scented cosmetics, etc. It is absolutely forbidden to use any kind of pesticides.
2. The last time (the fifth time) the cocoon is peeled and turned into a pupa. After about 7- 10 days, the pupa will become a silkworm moth and break out of the cocoon.
3. In the process of cocoon formation, it is best not to tamper with the silkworm rearing box or touch the silkworm baby with hands or other objects. At this time, silkworm babies need to cocoon quietly.
