2. When the silkworm spins silk, its body is moving and its head is shaking back and forth.
3. After silkworms spin silk, their bodies become smaller and lurk inside.
Silkworm babies feed on mulberry leaves After eating mulberry leaves continuously, the body turned white and began to peel after a period of time. When peeling for a day or so, if you can't eat or move like sleeping, it's called "dormancy". Once peeled off, it is a second-instar larva. Even if you molt once, it will increase by one year, and the larvae will molt four times to become fifth instar larvae. After eating mulberry leaves for 8 days, they will become mature silkworms and start spinning and cocooning.
Extended data:
Male silkworms spin more silk.
The chubby silkworm baby is really cute. This is not only white and clean, but more importantly, it can turn mulberry leaves into white silk. Silkworms like to raise more male silkworms, because male silkworms produce more silk and consume less mulberry leaves than female silkworms. Male silkworms eat less but spin more, which is also based on the characteristics of silkworms.
The adult life of male moths is shorter than that of female moths, and they usually die after mating with female moths. Female moths will produce a large number of eggs after mating. Both male and female moths don't eat or drink, and rely on substances accumulated in their bodies to maintain their lives. The substances accumulated in male moths are less, while those accumulated in female moths are more. Because the male moth dies after mating, while the female moth lays eggs for a long time to continue the race.
Male silkworms need less substances for gonad development, unlike female silkworms, which need to store eggs in their bodies. Therefore, male silkworms can convert more substances into silk and spit them out to become cocoons.
