Silkworm moth introduction, is silkworm moth a larva of silkworm?

On the contrary, silkworms are the larvae of silkworm moths.

The stages of silkworm life are from silkworm eggs to larvae, then from larva to silkworm pupae, and then from silkworm pupae to adults.

Silkworm (scientific name: bombyx mori) is a lepidopteran insect, the main raw material of silk**, which occupies an important position in the economic life and cultural history of mankind. Native to China, South China and Taiwan, commonly known as silkworm babies or mothers.

The silkworm is called "silkworm" (meaning "silkworm") because it uses silk to weave cocoons. The cocoon is woven from a single piece of silk 300-900 meters long. Nowadays, China's cocoon silk production and export volume account for more than 70% of the world's total, and has become a major cocoon silk country that can dominate the world's cocoon silk trend.

Ant silkworm: When the silkworm hatches from the silkworm egg, the color of the body is brown or black, very small, and many fine hairs, and it looks a bit like an ant, so it is called an ant silkworm. The antworm is about 2 mm long and about 2 mm wide, and after crawling out of the egg shell, it will eat mulberry leaves after 2 to 3 hours.

Silkworm babies eat a lot of mulberry, so they grow very quickly and their body color gradually fades. However, its appetite gradually decreases and even fasts completely, it spits out a small amount of silk, fixes its gastropods on the silkworm seat, raises its head and thorax, and no longer moves, as if it is asleep, which is called "sleep".

The sleeping silkworm seems to be stationary on the outside, but the body is preparing to shed its skin, and after taking off the old skin, the growth of the silkworm will enter a new instar stage, from the ant silkworm to the silkworm cocoon molting a total of 4 times. Sleeping is one of the growth characteristics of silkworms, and sleep is a genetic trait of silkworms, which is also affected by the environment. At present, the silkworms raised in China belong to the Hongmai Hui four-sleep variety.

Male and female silkworm moths can be put together artificially.

Silkworms reproduce with eggs, which look like thin sesame seeds, about 1 mm wide and about mm thick. A female moth can lay 400 500 silkworm eggs. 1700 2000 silkworm eggs weigh about 1 gram and are in diameter. Stuffy beams.

The color of silkworm eggs is pale yellow or yellow when it is first laid, and it becomes pale red bean color and red bean color after 1 2 days, and then becomes gray-green or purple after 3 or 4 days, and then it no longer changes, and gradually develops into an ant silkworm, which crawls out of the egg shell, and becomes white or light yellow after the egg shell is empty.

Silkworm pupae:

After the silkworm has formed a cocoon on the silkworm for about 4 days, it will become a pupae. The body shape of the silkworm chrysalis resembles a spindle, divided into three body segments: head, thorax and abdomen. The head is small, with compound eyes, and the thorax has thoracoped, pedal, and wings; The bulging abdomen has 9 segments.

Professionals are able to distinguish males and females from the lines and brown dots on the abdomen of silkworm pupa. When the silkworm first pupates, the body color is pale yellow, the pupal body is tender and soft, and gradually it will become yellow, yellow-brown or brown, and the pupal skin is also hard.

After about 12-15 days, when the pupal body begins to soften again and the pupal skin is a little wrinkled, it will become a moth.
