I still remember that the weather was fine and the spring was bright that day, which was a good season for sericulture. My classmates gave me some silkworm eggs. I put them neatly on a piece of paper like a baby, and put some mulberry leaves next to them, just waiting for my silkworm baby to come out quickly.
One day passed and two days passed. Under my expectation, I finally saw a silkworm egg slowly turning black and then climbed out with small black spots. I was so happy that I quickly put a mulberry leaf in front of it. Ten minutes later, a small gap appeared on the mulberry leaf. Oh! My silkworm baby ate mulberry leaves, and I was relieved, but I was too lonely. I hope its brothers and sisters will come out soon!
One, two,,,, my silkworm babies came out one by one. They grow up day by day. They have taken off their little black clothes and put on their white coats. They have a good appetite. If you listen to them, you can still hear the rustling of mulberry leaves. Their mouths are like serrated teeth. Everywhere you go, there are saws, and some silkworm babies are more naughty. Simply dig a big hole from the middle of mulberry leaves. I am so happy to see them grow up healthily! But a few days later, an unexpected thing happened.
When I came home from school that day, I dropped my schoolbag and went to see the silkworm baby. Oh, dear! I feel horrible. I saw several silkworms curled up and motionless. I put mulberry leaves on its mouth, and they didn't seem to see it. Are they sick? Or did you eat poisonous mulberry leaves? No way! I've been picking mulberry leaves in the same place! what can I do? Finally, I was cruel and simply threw them into the trash can. I told my father about it when he came back. My father looked at the rest of my silkworm babies and said that they were molting. It will grow up once it molts, and it will molt its silkworm baby 4~5 times in its life. I quickly picked up the silkworm baby who was sentenced to death by me from the trash can. Oh, dear! Because of their ignorance, they almost ruined their lives.
In the following days, I took care of my silkworm baby more carefully. One day, they stopped eating. They held their heads high and twisted back and forth along the branches of mulberry leaves. I looked at it carefully. Oh! It turned out to be spinning! After a while, I watched the white fat silkworm baby disappear, and all that was left was the beautiful cocoon I was holding now.
Through this sericulture, I not only increased my knowledge, but also gained happiness. Next year, I will raise silkworms.

When spring comes, everything wakes up, and silkworm babies are no exception.
My family keeps a box of silkworm babies. A few weeks ago, they just wriggled out of a small black nest not much bigger than rice grains. They are so cute!
They are dressed in black, three or four millimeters long, with round heads and walking as slowly as little turtles. When you pinch it, you will feel that it is too pitiful to pinch it hard!
Two days later, when I fed them fresh mulberry leaves, their steps were a little faster than usual, and they gradually climbed onto brand-new mulberry leaves and chewed them. When you are full, pat your stomach and slowly climb onto other mulberry leaves to have a rest and play. At the end of the day, a piece of green mulberry leaves is covered with holes, just like the green hollowed-out clothes carefully carved by silkworm babies, which are very beautiful!
A week later, their hair turned white and their bodies gradually turned white, much longer and bigger than before. Grandma said that when the silkworm baby is born, the mulberry leaves should be cut into small pieces, otherwise the silkworm baby will be crushed to death. Not if it's bigger, but I'll cut the mulberry leaves into small pieces just in case.
Two weeks later, the silkworm baby became "Snow White", all white and chubby. When eating mulberry leaves, you will hear the sound of sand, sand and sand. What beautiful music this is. One day, I couldn't help it anymore, so I held my breath, carefully picked up one, touched its soft and smooth body, and couldn't help but put it on my lips and kissed it. Wow! Cool, very comfortable!
After another week, the silkworm baby became transparent and slightly yellow. Grandma said they should cocoon. Really, they stopped eating mulberry leaves and slowly climbed to the corner of the box and began to spin silk. I saw a baby silkworm holding its head high, winding the thin and smooth silk thread around its mouth, and finally getting denser and denser, forming an oval transparent ball, and vaguely seeing its busy figure from the outside. Three days later, a pale yellow cocoon was woven! At this time, if you open the box, you will see their busy figures in every corner. Then, a milky, light green, orange and dark yellow cocoon was born. It is said that the young silkworm in the cocoon will become a beautiful moth in the future.
Spring silkworm, you "ate mulberry leaves and spit out silk", I praise you!

The sun is shining, the wind is sunny and the spring is warm in bloom, which is a good time to raise silkworms. There was a gust of sericulture in the class, and all of them became sericulture households. I was a little touched and thought: Silkworm rearing is so popular in my class that I can't go out! So, I asked the science teacher for some silkworms and put them in a prepared metal box.
At first, it was a small black dot lying on the newspaper, black and round, small and flat, like a small black sesame. While looking forward to its appearance, I also considered an important question: I don't have mulberry leaves! I asked my classmates for mulberry leaves, and they were smart enough to start selling mulberry leaves. I couldn't help it. I began to ask my grandfather for help. Grandpa knew about it and gave me a big bag of mulberry leaves the next day. I was surprised and asked him where he picked it. Grandpa said it was picked on the mountain. There are many on the mountain! I don't have to worry about mulberry leaves this time.
Within two days, some silkworm babies hatched and came into this world. It's black and small. When it doesn't move, it can hardly see its own feet and can't tell which is the head and which is the ass. Its flexible head moves around, looking around the unfamiliar world and finding that everything is so interesting and novel.
Gradually, the silkworm exposed its white head. Soon, the whole silkworm turned white. The head stretched out and shrank, climbing step by step. Some of my silkworms are white and some are black and white. At first I thought they were ill, so I was busy asking my classmates. Later, I learned that black and white silkworms are called zebra silkworms. Looking at these lovely silkworm babies, I am extremely happy.
Silkworms grow really fast, about two to three centimeters long, and the longest is four centimeters. Grow fast and eat more. Look, it chose a suitable position, climbed to where, held the mulberry leaves, began to move its head up and down, greedily gnawed at the mulberry leaves, and kept eating back and forth in one place until it was riddled with holes. Eat more Dora. Its poop was black, and it came out soon, which made me fall down for a while. One day, I found that the silkworm baby kept looking up under the desk lamp. I quickly asked my father what was going on. My father said, "Silkworms can't be in direct sunlight or under lights." As he spoke, Dad found a lid with several holes. This is good for the growth of silkworm babies. Dad said this when he left.
Silkworms always shed their skins three times in their lives. When it molts, its body stretches and contracts, writhes, its skin dries slowly, and then molts little by little. The molting silkworm is whiter and looks great!
Silkworm baby has grown up, white and tender, five or six centimeters long. But it stopped eating because it was going to cocoon. Look, it first built a rough outline with silk, drilled in by itself and surrounded itself with silk. You can see it vaguely at first. Later, when the silk was thick, silkworms could not be seen, only oval cocoons could be seen. Cocoons come in three colors: white, yellow and purple. They are put in boxes one by one. They are very beautiful!

There is a trend of sericulture in our school. Seeing that other students are well-informed in sericulture, I can't help asking my classmates for some silkworm eggs.
They are even smaller than sesame seeds, lying quietly on a piece of paper without competition.
Looking forward to it coming out early every day, let me see its true face. Finally, he came out. When he came out, the little silkworm struggled and twisted, and slowly the whole body came out, half brown and half black, with a total length of about 5 mm, looking for delicious food on mulberry leaves several times larger than it.
A few days later, the little silkworm grew up and became a one-centimeter silkworm. It eats a lot of food every day. Put the mulberry leaves in, and it will be finished in a moment. It eats a lot and poops a lot, and it has to be cleaned up every day. However, Zhou Xiao grew up gradually, and I worked harder and became stronger.
A few weeks later, when I looked at it again, it had turned into a big cockroach, and its body turned white, walking comfortably on mulberry leaves and enjoying the happiness of life.
After a few days, I found that the silkworm's body is transparent and mulberry leaves eat very little. I thought the silkworm was going to die. So I quickly asked my father, who lit my little nose and said, "He's going to cocoon! Carefully observe how silkworms cocoon and find out what self-cocoon is. "
When I came home from school, as soon as I opened the silkworm box, I saw a cocoon, so I shouted, "Cocoon, cocoon." Happy, like a white rabbit, with more and more cocoons and more colors, including white, yellow, light yellow and pink.
I am extremely happy, because I have successfully raised silkworms and learned some principles of being a human being.

In a science class, our science teacher said, "I have some magical treasures." If anyone wants it, come to my office after class, and the number can be limited. " . After class, I followed the teacher closely with great curiosity. The teacher really understands my feelings. As soon as I got to the office, I took out a piece of paper with particles on it and said, "These treasures are called silkworm eggs. Only careful, diligent and observant students can truly discover their magic. I believe you are the best. " Thank you, teacher. I said as I walked back with "baby" in my hand.
Silkworm eggs are small, black, flat and round. I help them have a home. Every day when I come back from school, I always look at them first. For a day or two, they waited for me motionless on the paper every day. I look forward to it every day, looking forward to the silkworm baby coming out quickly.
A week passed, and one morning, I was surprised to find that the silkworm baby came out. I saw several thin and small silkworm babies, smaller than black sesame seeds. I began to climb the arch as soon as I came out, but as soon as I came out, the days of suffering came. Because I haven't found the silkworm food-mulberry leaves.
A few days later, they were still hungry and miserable. I was sad to see them hungry, so I called my father for help. Two days later, my father came back and he picked a bag of mulberry leaves for me. I am in a hurry to feed silkworms with joy. Silkworms grow up day by day, constantly taking off the "magic spell of bones and muscles", becoming thicker and longer, white and fat, and their bodies become much brighter.
Silkworm babies grow up and eat more. They are not as good as when they were young. We should constantly add "rice" to them, watch them eat really well, and make some rustling sounds from time to time, as if it were raining. Silkworms sometimes hold their heads high and keep their mouths moving, but they can't see the silk they spit out, as if they were having a little meeting.
One night, I went to feed the silkworms again. I found that two big silkworms stopped eating mulberry leaves. One climbed up and down, one hid in the corner, and the other climbed to the roof. The next morning, two silkworms disappeared, only a white and a yellow oval thing were seen. My mother said it was a cocoon. After a while, silkworm moths and silkworms will come out of it. Oh, it turns out that the life of silkworms has changed so magically. I can't help but think of a sentence: "Silkworms in spring will weave until they die, and candles will cry the wick away every night." Isn't this a true portrayal of the selfless dedication of silkworm babies? Silkworm's life span is short, but its spirit shines forever.

Spring is here before you know it! Her arrival also gave life to a beautiful bug.
That's a silkworm. I have silkworms, too
In the spring sunshine, some small creatures were born in the silkworm eggs. They are all black and ugly, very ugly. Grandma told me that this newborn silkworm is called ant silkworm. Because just born, the body is very small, especially like ants, so it is called ant silkworm. The newborn ant silkworm greedily ate the mulberry leaves I put in the box. As if growing up overnight!
Next, after several molts, the silkworm grows up, its skin turns white and its body becomes the size of a finger. At this time, silkworms are white and fat, and they become very attractive. Grandma told me that silkworms at this time are called adult silkworms.
About 40 days, silkworms began to spin silk! It first found a triangular bracket, then spun silk and fixed it, and began to cocoon. A few days later, the silkworm wrapped itself in its "small room". Cocoons are colorful, mostly white and yellow cocoons.
Silkworm's life is short, but it is meaningful. This reminds me of the poem "Spring silkworms will keep spinning until they die". The moth that came out of the cocoon gave birth to the seed and died. No one can understand why silkworms end their lives in such a tragic way.
Silkworm! I love your life! From then on, I thought, our life must be meaningful! So we won't live up to our parents' expectations! Will make due contributions to society!
