Life Composition of Silkworm Baby 1 Do you want to know how Silkworm Baby spent his life? Then I'll tell you.
Silkworm life begins with silkworm eggs. Silkworm eggs are glued to paper, which looks dense, like a beautiful painting paved with small sesame seeds.
In spring, the little life in the silkworm eggs hatches! I saw the little ant silkworm in the dark, wriggling like a little ant. It is covered with fine hair. After the ants hatch, they begin to eat mulberry leaves in an hour or two.
After four or five days of incubation, the color of the ant silkworm gradually becomes pale and white. Slowly, the silkworm baby is white and fat, with a little black spots on it, just like the window on a train carriage. Its body feels smooth, cold and soft.
Silkworm babies squirm like waves when molting, and their bodies become whiter and brighter after molting. It takes one day to molt each time, and nearly 30 days to molt four times before and after. At this time, the body of the silkworm baby will be 6-7 cm long.
Silkworm babies will cocoon after molting for four times. When it cocoons, it turns around and keeps busy. It spits out more and more silk, the cocoon is thicker and thicker, and the figure of the silkworm baby is becoming more and more blurred. It takes two days and two nights to cocoon, and the silkworm spins silk as long as1500 m.
At this time, the silkworm baby sleeping in the cocoon has become a pupa. The pupa is brown and oval. Don't think that pupae sleep quietly in cocoons. In fact, it is hiding inside and changing quietly. In about 10 day, the pupa will become a silkworm moth and fly out of the cocoon.
Silkworm moths are white, like butterflies. A female moth can lay 500 eggs a night. How's it going? What a "hero mother".
People often say that "silkworms in spring will weave until they die". Silkworm has dedicated everything to human beings, leaving a brilliant world. We should learn from the selfless dedication of silkworms.

A Silkworm Baby's Life Composition 2 In the early morning, I vaguely opened my sleepy eyes, and bundles of golden sunshine shone directly on the carton where I put the silkworm baby through the window. Vaguely, I saw the box crawling with many small ants. Go in and have a look. Oh, the silkworm baby is out of its shell!
A young silkworm just hatched from an egg is like a little black ant. People used to call it "ant silkworm", and its body was covered with fine hairs. After about two days, the hair is not obvious. I watched it day by day, fed it day by day, and looked forward to it day by day.
In this sunny and fragrant spring, silkworm babies have been eating mulberry leaves. Suddenly one day, the silkworm baby lay motionless on the mulberry leaf. I was so nervous that I called my mother at once. My mother said to me slowly, "don't be nervous, it's called dormancy, and the silkworm baby is molting!" " "Oh, I see. My hanging heart is finally relieved.
After molting, the silkworm baby has been eating and lying down. Finally made a name for himself-from a black and small ant silkworm to a fat silkworm treasure in vain; It finally became famous-it made the dark body "lie" in white and bright!
Silkworm baby stopped eating again, but this time I'm not nervous. Because I knew this day would come from my mother the other day. Looking for a place with branches (prepared by my mother and I in advance), the silkworm baby began to spin silk continuously, and slowly formed a translucent ellipsoid, and the silkworm baby's body became smaller. Later, the cocoon became thicker and thicker, and the baby silkworm became smaller and smaller. Finally, one day I can't see the silkworm baby. My mother told me, "It won't be long before the young silkworm will break out of its cocoon and fly to the blue sky."
My mother's words still ring in my ears, reminding me of the famous sentence "Spring silkworms will keep spinning until they die, and candles will drain the wick every night".
"Silkworms will weave until they die in spring." This is the life of silkworm babies!
Silkworm Baby Composition 3 Life is slowly activating, just like a bare land, full of vitality. Open the box, look at the little silkworm eggs, sing to them, grow up with them, touch them, care for them, look up at the sky, think of last year's silkworm mother, give birth to her own children, and leave this world with a smile. When they first saw their children, they tore off their wings as they wished. Explain the touching moments they had!
The lovely' Silkworm Baby' finally broke through the cocoon! At first sight they are cute, at first sight they are naive and at first sight they are naughty! Among my most precious things, it must be unique I fed them mulberry leaves. The first time they ate mulberry leaves, they stared at them curiously. Some just thought that UFOs had fallen into their territory, some said it was a dimensional gate, groping for the entrance with weak hands, and some lazy people even regarded mulberry leaves as a canopy given to them by God and slept under them. I bent over and smiled, and finally they got carried away.
In this way, they grow up slowly, and it is time to cocoon and become mothers. When they sleep, they are ready to leave. They make their own hammocks, get in and close the exits. A few days later, alas, it was too late. Silkworm mothers, leave ~, bid farewell to silkworm mothers, I am staring at their little eggs.
In two years, two births of life also mean two deaths of life. Let's cherish life and cherish every bit!
In this world, many things will change. The caterpillar will become a butterfly, the ugly duckling will become a white swan and Cinderella will become a princess. What will the life of silkworm babies be like? I really want to know.
When the science teacher asked us to take the silkworm eggs out of the refrigerator to hatch, I began to itch to try. My mind is full of whimsy: what color is the newly hatched silkworm baby? What silk and color can a silkworm baby spit out? Finally, I look forward to going to school. As soon as I got home, I forgot to eat snacks and ran to the refrigerator at the same speed as the wind. I took out the silkworm eggs and gently put them in an empty shoe box, just waiting for the silkworm babies to hatch.
I don't know how many days later, one morning, a few dark little things crawled out of the silkworm eggs. The science teacher said they were called ants.
Soon, the young silkworm became a five-year-old silkworm, and its body changed from gray-black to bluish-white, which was also a big circle. I like to watch silkworm babies shake their heads when they eat mulberry leaves, as if to say: delicious, delicious.
One day I woke up to see silkworms. Many silkworms were gone, but there were some white things. Later, I learned that the silkworm baby was inside!
One weekend morning, I shouted, "This is a big deal. Moths invade the silkworm baby's home and get the silkworm baby out of the cocoon and eat it! " "Mom said," Don't make a fuss, these moths are made of baby silkworms, and their bellies are matched together! ""At this moment, my hanging heart was put down.
I stared at moths until they planted the seeds of life.
Life Composition of Silkworm Baby 5 I am Silkworm Treasure. Seeing Silkworm Love, mulberry flowers and mulberry trees are sad.
I live in an airtight house. It's dark and small, crowded and crowded, stuffy and stuffy. I really want to escape from it. No way, I can only use my unique skill-Jiuyin Bones Claw. I've been scratching with my hands. As a result, many things happen. I finally scratched the house and saw the first ray of sunshine in my life.
I came out of the house. I found my head is big, my body is gray and a little hairy. It's far from what I thought before because I look like an ant, and people call us ant silkworms.
Suddenly, my stomach sang an empty plan. "Uh-huh" a burst of fragrance. I smell left and right, and I see more than a dozen huge mulberry leaves not far away. I immediately turned around in lightning speed and began to chew mulberry leaves crazily. "ah!" This is really a' silkworm room dish'! I ate with relish and couldn't stop. After eating, I began to sleep motionless. I woke up and found myself instantly changed from Cinderella to Snow White. After four molts, I gained a new skill-spinning. Am I the legendary Spider-Man? I immediately built a villa with my silk. After the completion, I fell asleep comfortably in the villa. After more than half a month, I finally woke up and found myself with another pair of wings. Isn't this my childhood dream?
Ah! I can finally fly!
Teacher's comment: The author writes about silkworms in the first person, combining the growth order of silkworms. Reasonable structure, natural connection and many internal activities. This is really a masterpiece!
I have many silkworm babies, which were given to me by my good friend Jia. In order to raise the silkworm baby fat and strong, with the help of my father, I read popular science books and checked the information on silkworm rearing. Silkworm is a wonderful creature, which goes through four stages in its life: egg, silkworm (larva), pupa and moth (adult). It will take about 20 to 28 days. Silkworm eggs are small, generally oval, slightly flat and slightly pointed at one end. Larvae just hatched from silkworm eggs are usually black and brown. The baby hatched from silkworm eggs is too small to catch up with an ant, so it is called "ant silkworm". After eating mulberries, ants absorb all kinds of nutrients, grow rapidly, and their body color gradually fades, showing bluish white.
When my good friend Jia gave me silkworm babies, they were in the larval stage. At that time, they were about 2 cm in length and bluish white in color. When larvae grow to a certain extent, they must take off their old skins and put on new ones before they can continue to grow. It's called molting. After four molts, silkworms will cocoon. At this time, the silkworm baby becomes white, fat and shiny. They gradually stopped eating mulberry, the silkworm body contracted and became slightly transparent, and began to spin silk and form cocoons.
When they spin silk, they will raise their heads, stick the silk in one place with their mouths, then turn their heads to another place and pull the silk over. Their heads turned around, and the silk in their mouths was pulled over to make a cocoon and wrap themselves up. It is really "self-trapping". The silkworm that my good friend Jia gave me is now cocooning! After the cocoon is formed, the silkworm molts and pupates in the cocoon. In a few days, the pupa in the cocoon will become a moth with wings and tentacles. They will struggle to get out of their cocoons, but their wings will lose the ability to fly and can only tremble.
Last Wednesday, Teacher Chu gave us a very lively and interesting natural lesson-Silkworm Baby. Are you curious? Let me tell you something;
Silkworm, also known as worm, consists of head, chest and abdomen. There are eight black spots on both sides of the body, and that is its breathing mouth. The growth process of silkworm from the first instar to the fifth instar requires four molts. During molting, it likes to lie lazily in mulberry leaves without eating or drinking. When molting, start from the head and then molt slowly from the tail to the feet. Walk slowly like a wave. When eating, I like to hold mulberry leaves with my front foot and bite them slowly with my mouth. It looks lovely.
Silkworm babies are also delicate animals, so you should be especially careful when feeding them. You need to add fresh dry mulberry leaves to it every day. You can't feed it wet mulberry leaves, or it will die. There is also a need to clean up silkworm excrement and mulberry leaf residues in time, as well as to remove sick and dead silkworms, so as to avoid bacterial infection affecting the growth of other silkworm babies. It should be noted that silkworm babies must not turn over when molting, otherwise they will die.
Silkworms are treasures, and cocoons can be made into silk quilts. Silkworm pupa contains extremely high protein, which can be made into delicious food. However, the silkworm excrement and the molted skin contain traditional Chinese medicine components, which can be used as medicine.
People say, "silkworms in spring will weave until they die." Silkworm gave all of it to human beings, leaving a brilliant legacy to the world. I want to learn from the selfless dedication of silkworms. After listening to my story, did you fall in love, too?
Silkworm Baby's Life Composition 8 Hello everyone! I am a well-known animal: silkworm. I'm wearing a white suit, some buttons (small black dots around me) and a small black hat (big black block on my head).
My appetite is amazing. I am a big git from morning till night. I can eat it all day and night. In the process of my growth, my weight will also increase to eight or nine thousand times! Speaking of eating, I'm not too picky about food. I am mainly a vegetarian: for example, there are more than 20 kinds of leaves, such as camel leaves, elm trees, lettuce and raw orchids. Among these foods, the food that makes me satisfied is mulberry leaves. I eat leaves, and I am very particular. Must be clean and hygienic. Mulberry leaves need to be washed and then dried with toilet paper, so that I can be healthy and not sick.
I am also very particular about sleeping: I sleep once every seven days, and then I can't move without eating or drinking. When I get enough sleep and full of energy, I will peel the skin off. Every time I peel my skin, I am one year older and my body grows surprisingly fast.
Why do I need peeling? Because my skin is made of chitin, it can't grow bigger with the growth of silkworms at all, so I have to change my clothes and take off my old clothes every time I sleep. When I shed my skin four times and became a fifth instar silkworm, I began to prepare to spin silk. When I grow into a moth, the female moth and the male moth will give birth to more silkworm babies together, but their parents will die soon, so the silkworm babies will begin to accept new tasks.
Let me tell you a secret. I am covered with treasure, silkworm, silkworm slough, cocoon skin, silkworm moth and silkworm excrement, all of which are precious Chinese medicines. The silkworm moth is made into wine and health drink, which can improve immunity after drinking. My biggest function is to spin silk, which can be made into clothes, quilts and so on. And silkworm excrement can also be used as a pillow, which is very helpful for sleeping. Look, I am a real silkworm baby.
Although the life span of our silkworms is short, we are busy every day, and we are willing to make greater contributions to mankind.
Silkworm baby's life composition 9 Silkworm is a reptile mollusk, which mainly eats mulberry leaves and has eight pairs of feet, consisting of three parts: head, chest and abdomen. It goes through five stages: egg, ant silkworm, mature silkworm, cocoon, moth, oviposition and death. Life is about 56 days. Eggs change from yellow to black. The shape is flat and round, and it will hatch when the temperature is above 25 degrees Celsius.
When the silkworm first hatched, it was an ant silkworm. Because it looks like an ant and is black, it is called an ant silkworm. Its excrement is black, like sand. Eating mulberry leaves is very small.
Silkworms molt slowly. From ants to mature silkworms, they don't eat when they molt. At this point, the silkworm has turned white. The excrement is getting bigger. I also found a meat thorn in the abdomen of the silkworm, with a line looming in the middle.
Silkworms are getting bigger and yellower. Why? Mother told me that silkworms are going to cocoon. The next day, I found that the cocoon shell was ready, and only the silkworms in it did not pupate.
Almost a week or two later, all the moths came out. The moth mated with the male moth and laid 300-500 eggs, and then the moth died.
This is the silkworm's life, sacrificing itself and leaving the best to the world. Its spirit is worth learning.
Life composition of silkworm baby 10 Looking at silkworm eggs, things have to start from that day ... When I came home from school that day, I saw a shop that bought silkworm eggs, so I couldn't help but buy a pack. When I got home, I opened the box, put the silkworm eggs in a plastic bag and waited patiently for the birth of the silkworm baby. Silkworm eggs are black, not much bigger than rice. One day when I came home from school, I saw something like a caterpillar jump out of the silkworm egg. It's dark. It turned out to be a silkworm baby. I picked a lot of green mulberry leaves for silkworm babies and put them in their "small house". They quickly climbed onto the mulberry leaves and began to eat. When they grew up, I found them eating mulberry leaves in a circle. After more than ten days, the silkworm baby grew to 10 cm and began to spin silk. I put the silkworm babies in a paper grid prepared in advance. Silkworm babies stretch out a lot of white silk and surround themselves. In a short time, the silkworm baby "disappeared" in the white "little house". Finally, one day, the silkworm baby emerged from the "small house".
At this time, the silkworm baby has become a moth. Grandma asked me to put a piece of white paper on the wall to catch moths on the wall. After a day and a night, the moth laid 40 eggs on the paper, which are now displayed in front of me. This is the life of a silkworm baby. They gave themselves and decorated others. Isn't their selfless dedication worth learning?
