Silkworm Introduction:
Silkworm is an insect that belongs to the lepidopteran silkworm family and is one of the important economic insects of humans. The lifespan of silkworms is relatively short, generally only about 30-40 days, but in this short period of time, silkworms will go through a complete life cycle from eggs, larvae, pupae to adults. The larval stage of a silkworm is the most important stage in its life cycle and the key to raising silkworms.
Silkworm larvae feed mainly on mulberry leaves, and each silkworm can eat hundreds of times its own body weight during the larval period.
The main use of silkworms is in the production of silk, and the silk threads in silkworm cocoons can be used to make various silk products. In addition to producing silk, silkworms can also be used in fields such as medical research and food processing. Silkworm breeding has a long history, as early as ancient China, there are records of silkworm raising, is one of the important economic industries in ancient China.
Now, silkworm breeding has become a global production industry, and the production and processing of silkworm cocoons has become an important economy in many countries.

Last week I brought back some silkworm babies, and they were black and black and white, and they were so cute. In the evening, Dad and I changed the mulberry leaves together, we first took white paper and spread it on the table, and then Dad changed the leftover mulberry leaves of the silkworm baby to a sheet, and finally put the silkworm baby on it, covered the lid, and tied the rubber band.
Three days have passed, and the black silkworm baby silkworm that is less than one centimeter has now become a white silkworm baby that is more than one centimeter. This is my first time raising silkworms, and when I get them back, I put them in the palm of my hand and count their legs ......
I love silkworm farming!

Another week passed, and the baby silkworm grew a lot, changing from black to white and yellow. I gently pressed it with my hand, the white silkworm baby body is harder, and the yellow silkworm baby body is softer, and the head is raised high, as if to say: "Don't press it, it hurts!" So I let go of my hand, and the silkworm baby ran away quickly.
Now the amount of mulberry leaves is also more, in the past, only to feed twice a day, now to feed three times, I really hope it can quickly form a cocoon!

Two weeks have passed, some silkworms have formed cocoons, there are four in total, they have three colors of yellow, white and orange, two of them are white, one is orange, and one is yellow, and the others have not yet formed cocoons. They are still eating, and some are starting to find a place to prepare their cocoons! Every day I watched them grow day by day and fed them mulberry leaves.
I wish they were forming cocoons soon!

Autumn has arrived, and the blue sky is as far as the eye can see. A few white clouds sometimes look like a running horse, sometimes like a horse running on the grassland, sometimes like a small fish swimming around in the water......A flock of geese flew south in a neat line, sometimes like a "one" character, sometimes like a "human" character. The leaves of Rehmannia slowly floated down from the trees, like butterflies flying. >>>More
Little ants. In the afternoon, my friends and I went to the vegetable patch to observe ants. I caught a very large ant, put it in a glass bottle, and kept it while watching. Because of its size, it was also named "Big Mac". >>>More
