When do you put silkworms in the cocoon net?

At the end of the fifth instar, silkworm babies gradually show mature characteristics. Put the mature silkworm in a special container or trap and the silkworm will put the net into the cocoon. After molting for the fourth time, when the silkworm grows to about 10 cm, it can be put into the grid and ready to cocoon. Silkworms grow up eating mulberry leaves and molt four times in their lives. They stop eating two days before they are ready to cocoon. At this time, they are fat and bright. In this case, you can put them in a grid. In order to facilitate their spinning, the cocoons produced are big and round.

Silkworm (scientific name: silkworm) also has other nicknames in Taiwan Province Province, such as Baby Silkworm and Niangzi. Silkworm is a completely abnormal insect, which goes through four stages: egg, larva, pupa and adult, and its wings develop in the larval stage.
