Part I: Silkworms

A few months ago, my house came to a few "rare guests" - silkworm babies. They are small, black, skin wrinkled, like 80-year-old granny, can be ugly. Mom bought their favorite mulberry leaves, feed them to eat, but also gave them a "home" - shoebox.

Gradually, the baby silkworms eat and sleep, after four fading grew up, became white and fat, lovely! Silkworms can be smart! Once the mulberry leaves are dry, they do not want to eat, they must be replaced with fresh ones. When the baby silkworms do not like to eat mulberry leaves, the body becomes smaller, the head constantly up, they have to spit cocoon. My family's silkworm baby cocoon has white, yellow two kinds of oval-shaped, the baby silkworm has been staying inside the spit out the last strand of silk. I do not know after a few days, I heard the box, "puff" sound, a look, the baby silkworm into a "moth" out of the cocoon, but also hatched a lot of black eggs. I heard my mom say that these eggs will become baby silkworms in the next year, and they will continue to eat mulberry leaves, spit out silk, form cocoons, turn into chrysalises, turn into moths, and hatch eggs again, which is really strange! Only the female moths will die in a short time, so poor!

There is a saying: "Silkworms to the death of silk," the short life of the baby silkworms but made a great contribution. They spit the silk was made into silk, silk quilt, to bring people warmth. Thank you, lovely, poor and honorable baby silkworms!

Part II: Lovely Silkworms

The day is gradually warming up, my family's silkworms woke up one after another from their dreams, broke eggs out, and could not wait to come to this beautiful world to see the grass, look at the flowers, and taste the fresh and delicious mulberry leaves.

The newborn silkworms are like a black thread, slow action, do not look closely really can not be seen, I put the newborn silkworms carefully from the "maternity ward" to my elaborate "bedroom" (a window shoe), ready to carefully observe the newborns. The newborns were carefully transferred from the "labor room" to my carefully made "bedroom" (a shoebox with a window), ready for a closer look.

They change almost every day, molting a layer of skin on the growth of a circle, until today, there have been a few of the black cotton jacket into a white shirt, I picked up a mulberry leaf from the "bedroom", I did not realize that there is a small silkworms are lying on the top of the deliciously eat, it was alarmed to spit out a thin and long transparent silk, the silk firmly in place. Transparent silk, the silk firmly hooked the mulberry leaf, it is nimble down the silk, so stop at the other end, leisurely swing, "snort", I can not help but laugh, this baby silkworms how interesting ah.

They eat mulberry leaves will make a "rustle" sound, close to listen to, like standing in the forest to listen to the wind, but also like the sound of the rain, eaten mulberry leaves, even and orderly, very much like steamed buns grates, they are very smart, if there is a fresh mulberry leaf above, they will be scrambling up, but they will not be able to eat. feast, but they will not fight for food, wolf swallowing at the same time but is a gentleman of poise.

This is my baby silkworm, isn't it cute?

Part 3: Lovely Silkworms Essay

We have many white and fat spring silkworms at home.

The silkworms have a white coat with some black dots on it. Their heads are round, like a ball. They are always shaking their heads, really like a little baby in the mouth said: "I want to eat mulberry leaves, I'm so hungry, you see my stomach grumbling!" Every time I see their poor appearance, I can not help but feed a few mulberry leaves. The fragrance of the mulberry leaves caused them to immediately wriggle their soft bodies, twisting and turning to climb up the mulberry leaves, side by side with a small head along the edge of the mulberry leaves, began to eat up with gusto. Rustling, rustling, just like the sound of rain outside the window. Don't look at their body is small, the meal can be big, they eat continuously, as if they can never eat enough.

Silkworms are really worthy of treasure ah, their excrement is called silkworm sand, can be given to the sheep as food, can also be used as organic fertilizer scattered in the farmland. Silkworm pupa after refining is extremely rich in nutrients, containing a fairly high protein. They spit out the silk can be woven into satin and knitted products, made into cotton jacket and silk quilt.

Silkworms have the spirit of selflessness, in order to create happiness for mankind they would rather sacrifice themselves. The spirit of the silkworm makes me respect them.

Part IV: Silkworms

The one who has been reclining all over the body is not a silkworm breeder. --Title

Science class teacher let us go home to raise silkworms, the requirements to start from the beginning should be well documented, to see the changes in its growth, after going home I let my mom got some silkworm seeds.

The eggs of the silkworm are larger than a grain of rice, white and a little black, sticking to the top of a piece of paper. After two days, a small black spot appeared inside the eggshell, more and more obvious, and later it was a small worm crawled out of the eggshell, I know this is a small silkworm. The body of the small silkworm is small, black-brown, full of hair, the form of ants, the teacher said it is called ants, hair called bristles.

Ant silkworms can eat mulberry leaves, growing very quickly, its body in the middle of the green, bristles become less, with the body of the growing body, the body color gradually become lighter, green inside white.

Starting on the fourth day, the larvae do not eat mulberry leaves, spit out some silky material, the stomach and tail wrapped around the silkworm leaves, motionless, I thought it was spitting silk cocoon, the teacher said that it is in the molt. Sure enough, after a day and night time, that is, take off the old skin, put on new clothes.

Just removed the skin of the silkworm began to eat food again, continue to grow, to a certain extent, about 6 days and then to shed skin. This time I know that it will molt again, I do not feed it, wait for it to molt and then start for it to eat mulberry leaves. In this way, it molted 4 times and ate a lot of food after each molt. Teacher said it has grown to five years old, it will spit silk cocoon, let me give it a small house. The five-year-old silkworm baby body front translucent state, and do not eat mulberry leaves, the head up very high, swaying from side to side, like in the dance, the mouth of a thin filament regular weaving in the small house. 3 days later, a white cocoon was made, my silkworm baby fell asleep in it.

Part 5: The Story of My Silkworm Baby and I

We all have pets, right? I am no exception, I have the lovely silkworm baby.

In a sunny afternoon, when my mother came home to bring me a few peculiar pets - baby silkworms, they are white and fat, white body with a few small black spots, and black sesame seeds as small as the eyes, staring at me curiously, soft little body, as if I a little force can pinch them to rot as if I could crush them with a little pressure. Only a few minutes, I fell in love with them, in the meantime, a lot of stories happened.

When I first got the baby silkworms, I didn't have their favorite food - mulberry leaves to feed them, and the babies were so hungry and impatient that they crawled around in the box and twisted their bodies. I was so anxious that I stomped my feet where I was. Suddenly, I saw the row of trees in the neighborhood and had a bright idea! Uncle Zhang, the caretaker, had mulberry trees, I could ask him for mulberry leaves! I dashed to Uncle Zhang's place. Unexpectedly, Uncle Zhang was so generous! He picked dozens of mulberry leaves from the tree and handed them to me. I was ecstatic, thanked Uncle Zhang, immediately ran back upstairs, ready to feed the hungry and anxious "baby". I just put the fresh mulberry leaves into the box in a clean place, the baby silkworms wriggled white fat body climbed over, aligned position, open mouth devouring up, I looked at them chewing the way, I was very happy. However, their meals are too large, not a moment to my "fruits of labor" to eliminate, completely ignoring my hard work. I want to cry, I had to ask Uncle Zhang for mulberry leaves again.

Day by day, watching the silkworms slowly grow up, I and the silkworms have been mixed very familiar, as the saying goes, "a day without seeing, such as the three autumns", I was "a second without seeing, such as the three autumns. One night, I had an idea that it would be great if I could put a baby silkworm on my nose! I was amazed and excited by my "great dream". I picked up one of the smaller silkworms and carefully moved it closer to my nose. ...... At this moment, my heart was pounding and my hands were trembling. Finally, the silkworm baby reached its destination, and I let go of my hand. Just when I was so excited, something unexpected happened - the silkworm baby had just arrived at a new place, not adapted, afraid, the body then shrunk into a ball, like a marshmallow on my nose and did not move, I hurried to take the silkworm baby off my nose. Now, I can comfortably put the silkworm baby on my nose.

Don't look at the baby silkworm body small, the use is not small! It spits out silk can do clothes, silk quilt, pupa can be fried to eat. In short, the use of a lot of it!

I like the baby silkworm, like its lovely appearance and broad use.

Part 6: Silkworms

Last semester, the science teacher distributed some silkworm eggs to each of our students. Just when I was puzzled, the teacher told us that we should take them home and raise them ourselves. As soon as I got the eggs, I was overjoyed. Because, I have long wanted to experience it myself. I did not expect the opportunity to come so timely.

Because the silkworm can spit silk cocoon, its silk can do clothes, can also do quilt, the role can be really big! I am determined to raise silkworms.

Only two days later, the baby silkworms came into the world. Look, a baby silkworms move around, seem to be looking for something. I think the baby silkworms are very cute, just like a little ant. Silkworms have many legs, and they are in pairs. They crawl very slowly, almost like snails. Ant silkworms eat mulberry leaves can be long-winded, not with the same mature silkworms, a large piece of a large area to throw down all right, ant silkworms eat 'mulberry leaves have to be cut into a small piece of a small piece.

After some days, the baby silkworms even refused to eat, I thought it was eaten to support. I was so anxious, busy requesting my mom to come and take a look. Mom heard, but also anxious, thought the baby silkworms have what disease. When she went to the baby silkworm, can not help but laugh, said: "children, silkworms to grow up, this is normal. It will molt in another day." Sure enough, the baby silkworms began to molt, their movements are very clumsy, but in step, only to see their back body does not move, the front head arch, the skin was pushed out a little ...... After many efforts, their narrow "flower clothes" successfully get rid of. After that, they lazily continue to sleep.

Time unknowingly passed, the baby silkworms also succeeded in molting four times, into the big baby silkworms. At this time, the baby silkworms are called mature silkworms, meaning that the mature baby silkworms. At this time, they know more, eat nothing picky, even if it is a large piece of mulberry leaves are okay.

Mature silkworms eat mulberry leaves for a few days, they began to spit silk cocoon. This time the baby silkworms can be really busy ah! They sleep inside the cocoon for ten days or so, they changed into moths, and began to reproduce the next generation.

Ah, so the life of the baby silkworms is so short. However, the baby silkworm has made its own contribution to us, it is worth learning. After this experience of raising silkworms, I decided to try to observe and learn more about the secrets of silkworm babies.

Part VII: Observation of Silkworms

I used a shoe box to make a "house" for the silkworms, which was first covered with a layer of mulberry leaves, and then the silkworms were placed in the center. The first layer of mulberry leaves in the "house", then put the baby silkworm in the center, and then spread mulberry leaves on the body of the baby silkworm.

The first time I saw the baby silkworms, the color was brown, and now it has become white and chubby, my aunt said that they are a little bit scary, but I think they are very cute!

I always thought that the baby silkworms are insects without feet. But when the babies stayed in the "house" for the fifth day or so, I got up in the morning to feed them mulberry leaves and saw them crawling instead of wriggling. I took a closer look and realized that the silkworms also had feet. So I grabbed a baby silkworm and put it on a mulberry leaf and observed it.

The head of the baby silkworm is very small, there is a big mouth; the chest is big with three pairs of feet, called the thoracic foot; the fullest place is the number of the abdomen; the abdomen below the four pairs of feet, called the abdominal foot; the tail is also a horn, called the tail horn; on both sides of the body there are nine black "dots", which is used by silkworms to breathe, called stomata; there is also a black stoma on the back, called the stomata. stomata; there is a black line on the back, which is what people call "blood vessels", the larger the baby silkworm blood vessels will see more clearly; the last point is the caudal foot.

Every time I change the mulberry leaves for the baby silkworms, they will stick to the leaves and can't shake them off. I will use fresh mulberry leaves and shake them in front of their brain door, and they will slowly crawl over as soon as they smell the fresh leaves.

I have not seen the molting scene that the adults said until now. But sometimes I feed mulberry leaves to pour silkworm baby stool, I will see a yellow insect shells, I thought it was in the picking of leaves to other insects also brought home by the way, insects dead and dry is this way, but the third time I saw the same insect shells, I think it should not be other insects. So I asked my mom and she said it was the skin of a baby silkworm. It's a shame I didn't get to see them molt.

My mom said that my baby silkworms will make cocoons in a week or so, so I'm looking forward to it!

Part VIII: Silkworms Growing Up

Mr. Ou brought a few silkworms to the class for us to raise, and we were all very happy.

The next day, Chen Yingxing brought a very delicate little "house" for our babies. The "house" is actually a milk carton, it is very wide, there is a hole in the top, ventilation, air, very suitable for the baby silkworms to live. The class handsome boy Peng Junxin volunteered, responsible for preparing food for the baby silkworms - mulberry leaves, so that the baby silkworms will not worry about food and clothing!

When the baby serpent first turned from an egg into a small silkworm, it was two to three millimeters high, like a small ant, so it has a name called "ant silkworm". It is very small and black all over. It is very lazy, in the box does not want to move a little.

A few days later, I found that the baby silkworm's head became white, the head is obviously bigger, and no longer as lazy as before, we put a mulberry leaf to the baby silkworm, the little silkworms immediately climbed up to eat, some from the edge of the inside, some from the middle of the outside to eat, there are also very cunning, see other silkworms in the middle of the mulberry leaf nibbled a hole, immediately pounced on the past, to the top of the other silkworms away from the position to dominate over.

About two weeks later, I found that the baby silkworms have become significantly different from before, before the silkworms and black and thin, now even became white and fat. In a few minutes, put down the mulberry leaves were eaten by them a half, really a "big appetite" ah! What's more interesting is that the baby silkworms sometimes do not move, not long from the back of the buttocks rolled out a small black ball, it turned out that it is in the poop ah! Listen to the science teacher said, the silkworm baby out of the poop or Chinese medicine!

Four weeks later, the baby silkworms are more able to eat. But a few days later, the body of the baby silk worm turned yellow, but do not eat, I was very strange, thought the baby silk worm is sick. A classmate said, "The silkworm is about to spit." Sure enough, in the past few days, the little silkworm climbed to the high place of the box and chose a corner to get ready for spitting. They began to spit out silk. They first spit out some silk to fix the location of the cocoon, and then spit back and forth to their own body, about a night to form a cocoon, white cocoon is like a small quail egg.

After ten days, the moths from the cocoon bite a small hole drilled out, and other moths after the tail began to lay eggs. The eggs are yellow, after a few days will become black, when the eggs become black is, the silkworm moth will die, it is the end of its life, it is really "the silkworm to the death of silk" ah!

In order to raise silkworm babies, we have paid a lot of effort, in our *** with the care, silkworm babies happily finished its life, we are very happy.
