1. How big can silkworms grow

Silkworms can grow up to 6-7 cm long. The silkworm will go through four molting times, each molting will grow larger, and the number of molting times is used to indicate the age of the silkworm. generally, the silkworm that has shed its skin four times can grow to 6-7 cm, belonging to the fifth instar silkworm. The fifth instar silkworm should begin to prepare for cocooning.

Second, the change of silkworm

The newly born ant silkworms are one-year-old silkworms, they are relatively fragile and black, and they can only eat tender mulberry leaves with a length of about 3-5 mm. After eating mulberry leaves, the ant silkworms become bigger and longer, lose their black, slowly turn white, and become second-instar silkworms after molting for the first time. It will continue to grow in the future, and the well-developed silkworms can grow to 6-7 cm after the fourth molting, and can eat some old leaves. Every time the silkworm molts, there will be a "sleep" phenomenon, keep a day without eating or drinking, at this time, we should not think that it is sick, and to interfere with it. The back of the fifth instar silkworm turns yellow and transparent, and it doesn't eat much mulberry leaves, indicating that it is going to start spinning and cocooning.
