Silkworm baby observation diary

Silkworm Baby Observation Diary 1 Every spring in our family, my mother likes to raise silkworm babies, but mulberry leaves are hard to find. My mother only keeps about 20, so I can observe and keep a diary.

I miss silkworm baby very much this spring, and I look forward to it every day! Hope! After Tomb-Sweeping Day, our white silkworm baby, black silkworm baby and flower silkworm baby climbed out to meet me. I am very happy to find mulberry leaves downstairs when I come back from school every day and come back to feed the silkworm baby. They are so delicate. Mulberry leaves cannot have water. If there is water, the baby silkworm will get sick and die after eating it. You can't make potions or light mosquito-repellent incense at home. Lovely silkworm babies sleep after eating and eat when they wake up. Getting bigger every day, molting, eating and growing up. Silkworm babies crawl out of their eggs like black sesame seeds, like little black ants. When the silkworm baby grows up, I like to put it on the back of my hand and let it crawl. Silkworm babies are soft and feel very comfortable.

After a month, the silkworm baby's body is transparent. Mother told me, "The babies are going up the hill." We will put the silkworm baby in another shoe box, and the silkworm baby will find a comfortable place to form an oval cocoon. With white and yellow cocoons, the shoe box will be full and beautiful. In a week or so, the pupa inside turned into a beautiful white moth girl, climbed out of the cocoon and began to breed the next generation. We'll meet again next spring, silkworm baby.

Silkworm Baby Observation Diary 2 Day 1 Day: Great! The teacher asked us to start sericulture today! This is my second sericulture. Silkworms are difficult to raise, or they will die. But I have the confidence to train them well.

The next day: Silkworm eggs are only as big as sesame seeds, so small that they can't be seen clearly, even if there are ten, there are very few. They are gray-black, round and a little flat in the middle. As long as you touch it gently, it will bounce off you. So at home, I kept them carefully. The teacher told us that as long as the silkworm eggs are transparent, it indicates the birth of new life. The newly hatched silkworm is called ant silkworm, which is small, thin and black, even smaller than ants. As I said just now, this is my second sericulture. Silkworms are difficult to raise, especially ant silkworms. You can only let them eat mulberry leaves and climb by themselves, and you must never pinch them. If you pinch it, it will be crushed to death. Just touch it gently with a brush.

The third day: I just found that some eggs are translucent under the light, and it seems that I can vaguely see the shape of a small silkworm! Some eggs are linked together. Will they come out together? Now I have to cover them with 1 layer cloth to prevent insects from eating them.

In order to have a good science class and raise silkworms, I always take silkworms to school carefully and prepare enough mulberry leaves. The picked mulberry leaves should be cleaned and put in the refrigerator for later use, so as to keep them fresh.

Ah, the little silkworm will appear soon!

Day 4: My silkworm baby is not born today, but almost all of them are faintly visible. It is said that touching other eggs after birth will help other eggs hatch. I don't think it's right, because I've never seen such a thing. I also looked up "100,000 whys" and didn't see this statement, but I found out why male silkworms spin more silk than female silkworms. This is because they use different substances in their bodies, so male silkworms spin more silk than female silkworms.

Although the silkworm baby has not yet been born, I silently wish it an early birth!

Day 5: Wow, that's great! My little silkworm has hatched! Some of them have unconsciously climbed onto the mulberry leaves I put, and some are still breaking out of their shells, which is very lively. They ate mulberry leaves and chewed delicious food, leaving traces on the mulberry leaves, indicating that this is where they have eaten. They are dark brown and have shiny heads. Some silkworms are entangled, and it is fun to break free. Their tails come out first and rub their shells hard, and it is the most difficult time to break free from their heads. Swallow hard because their heads are big, so it's difficult.

Great, my silkworm has finally hatched.

Day 6: Because ants are afraid of light, I cover them with newspaper and let them eat mulberry leaves. Well, I saw a terrible scene at a classmate's house-a little silkworm hatched, its small tail stretched out first, and its body was going out smoothly, but in the end it couldn't get out no matter how hard it tried. It struggled, broke free and rubbed, but it just couldn't get out. Finally, he died because he was too strong and exhausted. Poor thing, this little life just passed away.

Ants and silkworms pull a lot of small stools, just like black coal dust.

Wish the silkworm baby grow up quickly!

Day 7: It was hot today. I was afraid that the ant silkworm would get sunburned, so I moved it to a cool place. When I fed them mulberry leaves, I found that they grew up a little. The front of the head is a little gray, black and white, and the body is fleshy. Small paws are like Mao Mao dregs, and the head is eating mulberry leaves up and down, which is very cute.

Ha, great, my silkworm has grown up!

Day 8: Wow, I went to see silkworms with my schoolbag on my back as soon as I got home. They grow fast and get bigger! The silkworm's head turned white, swollen and covered with meat. That's great. I have to feed it well and I can't live up to the teacher's expectations. I put the mulberry leaves into the silkworm box one by one, and soon, my little silkworm climbed sensitively to the new leaves, dense and dense. I must keep it well.

Oh, great, my silkworm is so big!

Day 9: My silkworm grew up after eating big and good mulberry leaves. The head piece can be white, especially drum and big. Teacher Wang's silkworm seems to grow very fast, too, and it will catch up with mine soon! Mom said that large groups of silkworms grow fast together, so they are longer than others and live better in groups. Don't believe it? Do not believe me, I will show it to you tomorrow!

All right! I will show you my silkworm tomorrow.

Day 10: It is very hot today. Will silkworms get hot? Are they afraid of heat? What's going on here? My silkworms haven't changed, and their heads are still white, but I find that they seem to have found a clever way to eat mulberry leaves. I cut the mulberry leaves into strips, and they find the edge of each leaf and eat the leaves into pieces. Mom said that this is the origin of "gnawing".

I'm so glad my silkworm can eat leaves! They should grow up quickly!

Day 1 1 day: My little silkworm can eat leaves! They stick their heads out from the sawtooth on the edge of mulberry leaves and chew on them. Now you can see their little mouths eating one by one. Listen carefully and you can hear the sound of "click click". It's all right! Silkworms seem to have three small mouths. It's interesting to see this.

I have a silkworm, so big that it stands out from the crowd! Its body is white, its head is black and bright, and it can crawl around and eat mulberry leaves. Oh, my silkworm has grown up, and the new mulberry leaves I fed are almost gone and swept away.

Ah, you know what? That big silkworm is 7-8 mm!

Day 12: Today is a sunny day. When I came home from school, I saw a big silkworm crawling slowly, as if looking for food. I quickly fed mulberry leaves to silkworms. Soon, I looked again, and all the silkworms climbed up the mulberry leaves. That big silkworm is good at eating. It moved its head up and down along the edge of the mulberry leaf, and soon it ate a big gap on one side of the mulberry leaf. It still greedily ate, ate and ate, and pulled out a lump of urine excrement-silkworm excrement. This silkworm excrement is much bigger than the original one, because it is good when it grows up (I mean silkworm is good).

My silkworm is going to grow up!

Day 13: My silkworm is big, much bigger than the original "one-year-old silkworm"! There are many white ones! There is a big silkworm that has grown to a centimeter and a millimeter, and it is growing well! They are very dense and should be fed several times a day. You can only feed it twice a day at school, once in the morning and once in the evening. As soon as they eat more, whoever can grab it will eat more. The more they catch, the more they eat, and the more they eat, the less they feel. So the silkworm grew up!

Great, silkworm!

Day 14: Today, I sent my silkworm to my grandma's house, because grandma also wants to raise silkworms. There is a big mulberry tree in her house. I told grandma the essentials of sericulture. I picked mulberry leaves and put them on the silkworm, and the silkworm will automatically climb up. I picked some mulberry leaves for my grandmother to see. Later, grandma took some pictures of me feeding silkworms, which was great. I was afraid of killing the silkworms when I took pictures, so the action was very light, but they grew up and stood the test.

Day 15: My little silkworms were hungry, so I fed them some mulberry leaves. I used to cut mulberry leaves into strips when feeding silkworms. Now, I don't need to cut it. As soon as I put the silkworm in, I will automatically climb up and eat it. After eating mulberry leaves, silkworms leave the stems layer by layer. I clean dry leaves and stems every day. But some silkworms always lie on the old petiole and can't eat new leaves. They were a little tired, so I put them on the new leaves to make them full. Silkworms eat all day and never stop. He is really a "slacker", but he left a rich legacy after his death, such as scarves, silk clothes and so on, all of which belong to him!

Ok, my silkworm has grown up, great!

Day 16: Today, I saw my silkworm baby is big and long, a little more than 2 cm, which seems to be a "third-instar silkworm". They are fat-not very fat, a little slim. If I were fatter, I would be a big silkworm. They may have eaten by now. It is not enough to feed it three times a day. Just after feeding, a large leaf will be "eaten" in a short time. Now the silkworm's head has changed from bright black to big gray black, which is very healthy. They ate mulberry leaves from beginning to end and were insatiable.

Silkworms grow fast!

Day 17: Today, my silkworm has not changed. But the poop is big and black, and there are many small white spots on it. Now the silkworm's head is gray and has grown up a lot. It seems that there are three mouths, and the body is segment by segment, which is not too white.

They are very edible now, and they have to be fed several times a day to ensure nutrition.

Day 18: There are several silkworm babies who are obviously big and stand out from the crowd, but they are fat! Mother said that silkworms are changing every day, because they are constantly eating, pulling and sleeping every day. You didn't notice them growing, just didn't observe them carefully. Although some silkworms have grown up, some are still very small. These young silkworms must hatch very late.

Those grown-up silkworms are smiling at me and praising me for raising them well, as if to tell me that other silkworms should also be raised. Don't worry, my silkworm baby

Day 19: Today, my silkworm seems to have grown up at once. Those big silkworms that stand out from the crowd are greedily eating the mulberry leaves I just fed. One of them swallowed it as soon as he found the leaf edge, and soon bit off a big gap. Eating mulberry leaves is really interesting. You go up and down and stretch your head back and forth.

When do those little silkworms grow up? When did it become as edible as a big silkworm?

Day 20: Today, several big silkworms are all yellow, no, to be exact, the skin is yellow, the tail is divided into two forks, the white tip on the tail is a little yellow, the meat at the back of the head is wrinkled into a ball, and there are two small gray-black curved lines at the back. There are two silkworms, which are combined together like a bracket, which is very interesting.

Silkworm grows up!

Day 2 1 day: It's a little cloudy, but-silkworms are molting! Second, it's not just the second molt. I saw a silkworm lying on the edge of the box with my own eyes. Its skin has fallen by half, and it is still working hard secretly, but you can't see it. Silkworms don't eat when they molt, as if they are ill, but they keep pushing hard and their skulls fall off.

Silkworms shed their skins! Once shed, it grows up again!

Day 22: Mom said that when silkworms haven't spun silk, they don't have to keep a diary every day, but they will write it every day when they spin silk. Now all the silkworms in my family have molted for the first time, most of them are about 4 cm long, but some are small, still very small, and may be the last to molt. Silkworms are all wet when they molt, and the molted skin is wet. I sometimes touch the silkworm's head and feel its head is hard. Silkworms are very big and their bodies are very white. There is a black line in the middle of the body, which is probably a "blood vessel"! The blood vessels in the tail twinkle. Silkworm claws are equivalent to suction cups, which can be scraped on objects, but they will not work if they touch smooth objects such as glass, and they will be invalid.

Day 23: Because we silkworms are gay, we can't raise children. He died a few days later. What a disappointment!

A month ago, the science teacher handed out some silkworm eggs and told us to hatch silkworm babies.

One day, two days, a week, a month, the silkworm baby finally hatched; First, a small hole was broken at one end of the egg, and then a black silkworm baby crawled out of it, which really looked like dander. At this time, the previous silkworm eggs became transparent shells. I checked the computer, and it turned out that her name was not silkworm, but silkworm ant; After about five or six days, I peeled off a layer of skin and turned gray. It crawls slowly on the mulberry leaves and looks really cute. Two weeks later, it peeled off another layer and turned white. Now you can observe carefully. Its head is big, its mouth is khaki, its eyes are above its mouth, but it has no ears. It feels sound through its skin and has seven pairs of feet. Its body is segmented. Silkworm babies eat, eat, climb and live freely on mulberry leaves every day.

I like this soft little guy and hope he can grow up healthily and quickly.

Silkworm Baby Observation Diary 4 In the morning, the sun shines beams of golden light on my window. I woke up in a daze. As soon as I came to the dining table, I found something like ants in the box. I looked at it carefully. "Ah, it's an ant silkworm!" "Listen to my mother:" Speaking of silkworm babies, when they grow up, they can spin silk and weave clothes with silk. "In order to preserve them, I quickly took some mulberry leaves, cut them into strips and put them in a box. I saw the ants eating with relish, as if they were hungry. I carefully observed that the ant silkworm is dark and soft to the touch. It nibbled at the pale green mulberry leaves, as if to say, "This mulberry leaf is really delicious! "

Two days later, the sun shone all over the earth. I was shocked when I saw the silkworm baby. It was clearly Cinderella's ant silkworm the day before yesterday, but today it is Snow White's silkworm baby. I looked into the box, and it turned out that the silkworm baby was peeling.

After four days, I thought: I wonder what happened to the silkworm baby? Hurriedly put your head in and sniffed, "Oh, it stinks! What's that smell? " I looked at it, and it turned out to be shit, black and bumpy. I thought: Silkworm babies can pick up shit!

About twenty days later, when I was ready to study, I went to see the silkworm baby by the way. Silkworm baby has spun silk, motionless, as if thinking about where spinning is more comfortable.

After three days, I got up in the morning and couldn't wait to see my silkworm baby. To my surprise, the silkworm baby turned into a cocoon, white and oval, which looked like a small egg. I thought: How can a silkworm baby eat mulberry leaves and spin silk?

After more than ten days, at night, the moth in the cocoon finally flew out. At this time, I saw a silkworm moth's stomach straight, and it was easy to see its eggs.

Five days later, I found the box full of ants and silkworms. I quickly called my mother to abort the silkworm baby. My mother threw it into the trash can without saying anything. Because we don't have so many mulberry leaves to feed so many silkworm babies. I thought: poor silkworm baby, God will protect you.

I have a history of sericulture for nearly two months. During these two months, I realized that sericulture is very hard. I feed the silkworm babies and clean the room every day. I also know that it has experienced eggs, larvae, pupae and adults in its life. With silkworms, the clothes we wear are made of thousands of silkworms, and countless workers have to raise silkworms. It's really hard!

What a great harvest this time!

Silkworm baby observation diary 5 The silkworm baby who came from Wang Zhequan last week is like a little ant. After my careful upbringing, I grew up gradually, and now I am as thick as pencil lead.

When they were young, I couldn't see clearly how they ate mulberry leaves. After they ate and crawled away, they found that the thin layer of things on the mulberry leaves was gone. Later, when they grow up a little, they can be observed eating mulberry leaves from top to bottom, that is, slowly feeding themselves in the repeated process of raising their heads and lowering their heads.

Up to today, my silkworm baby has shed its skin twice, from black to gray.

I remember the first time they molted, they were motionless. I thought they were going to die. I was so anxious. Later, my mother told me that I might not be able to eat any more because I was going to shed my skin. Sure enough, I woke up the next day and found that there were black spots on the mulberry leaves. It was really their molting! Mom said that after molting, the silkworm baby will grow up a little.

When I got home today, I hurried to see my little silkworms, and found that they didn't move again, and the mulberry leaves only ate a little. I thought it was time to molt again, so I quietly observed them and found a little silkworm lying on its side. After I helped him lie down, he wriggled and crawled forward. Slowly, I found that the skin on both sides of its body gradually bulged out, and then I peeled it back a little. At the tail, the shed skin can't fall off. I'm nervous and anxious. I really want to give him a hand and tear it up. But my mother told me not to touch it and said it would work hard by itself. At this time, the silkworm baby always squirms, and the tail that does not swing begins to swing from side to side. Through our own efforts, the skin finally fell off. I'm sweating for him. I'm so happy for it! When I went to see it again, I saw it lying on the mulberry leaf, with its head held high and never moving again. I guess I was exhausted just now, and I'm taking a good rest now! At this moment, I suddenly found something dark and bright on the mulberry leaf. My mother said it was its mouth. Really, the mouth after molting is bigger than other silkworm babies, and it is gray! Mom said that if the mouth is only a little black, it's time for them to shed their skin.

Today, I am very happy, because I saw the second molting process of silkworm babies.

Observation Diary of Silkworm Baby on June 6th1Saturday, Monday will be fine.

Today, we received the silkworm baby. We are all very happy. I got eight eggs of silkworm babies. They are black and small, just like sesame seeds. I will often observe them with a magnifying glass, hoping that silkworm eggs can hatch immediately. But eight small silkworm eggs lay quietly on a small piece of yellow paper and did not move.

20xx On Tuesday, April 24th, heavy rain turned to light rain.

Today, my silkworm baby finally hatched! I only hatched two when I got up, and by the time grandma released the mulberry leaves, there were already five. At night, there were already seven. They come out of the eggshell, dark and as small as ants. The eggshell has also changed from black to beige, which looks crystal clear. I gently pulled the hatched silkworm babies onto the feathered mulberry leaves. Although they are very young, they are very clever. They will avoid the thick stems on mulberry leaves and look for the most tender and delicious places to eat, and soon there will be many small holes on mulberry leaves.

But there is still a silkworm baby that hasn't hatched. I think it should hatch tomorrow. I hope they will grow up quickly, cocoon early and become beautiful moths early.

Wednesday, May 2nd, 20xx will be fine.

Silkworm babies are already very big. They keep eating mulberry leaves and occasionally kiss the box with their small mouths, which is very cute. I saw a strange thing when I was looking at the silkworm baby just now. It is yellow. I went to ask my mother, and she said that the silkworm baby took off its skin! Mom said that silkworm babies grow up molting.

20xx May 13 Sunday cloudy with light rain.

After breakfast this morning, I went to my room to see if the silkworm baby had finished eating mulberry leaves. At first glance, I really finished eating. I quickly ran to the refrigerator to feed mulberry leaves to silkworm babies. This is the last mulberry leaf.

At noon, the silkworm baby finished eating the mulberry leaves again, and there were no mulberry leaves in the refrigerator. So my mother and I decided to go to the school reception room to get some mulberry leaves. But the security uncle in the reception office said that the mulberry leaves were gone and the new ones had not been delivered yet. What shall we do? My silkworm baby is starving. Seeing that we were in such a hurry, Uncle Bao told us that there was a mulberry tree near the school wall, and we could pick some.

My mother and I searched for a long time, but we couldn't find the mulberry tree. We have to ask uncle security again. Uncle Security told us the route in detail. We searched for the mulberry tree all the way along the route taught by Uncle Security. Finally, on the edge of the wall of the teaching building, I found the small mulberry tree that was not lush. The mulberry leaves on this small mulberry tree may have been picked by other children, so there are not many leaves. But there are still some green mulberry leaves on the branches, which look very fresh. There are two pink mulberries on two branches, which are very attractive.

My mother and I picked some mulberry leaves, and we want to pick more. It suddenly occurred to me that maybe other children don't have mulberry leaves either. If we pick all the mulberry leaves, their silkworm babies will have no mulberry leaves to eat. Let's leave some for them.

Holding the picked mulberry leaves, I ran home quickly first. My little silkworm is hungry. I quickly took a tender mulberry leaf to feed them. When the baby silkworm saw the food, she immediately climbed onto the mulberry leaf and ate it. My mother and I both smiled with relief when we saw the silkworm baby eating so happily. Our efforts were not in vain!

It will be sunny on Thursday, May 17.

When I went to see the silkworm babies in the evening, I found that four silkworm babies had stopped eating silkworm leaves. And their body color is a little yellow, not as white as before. There is some silk around them. Oh, my baby silkworm should spin silk and form cocoons. Dad taught me to separate these four silkworm babies in other boxes. Keep them safe inside.

It will be sunny on Tuesday, May 22nd.

Up to today, all my eight silkworm babies have cocooned. Seven are orange and one is light yellow. Its color is very beautiful. I picked up a cocoon, shook it in my ear, and heard the sound of silkworm chrysalis rolling inside.

Silkworm baby is really a wonderful creature. It took them 37 days to change from small black eggs as big as sesame seeds to beautiful cocoons. In these 37 days, they molted four times, and each molting was a training for them. They also grow with each molting and tempering. It only eats ordinary mulberry leaves, but the silk it spits out is so pure and beautiful. In ancient times, our ancients used it to make noble silk and spread it all over the world. Let people all over the world know about China from silk.

Our Hangzhou is known as the "Silk House", and many silk products have won national quality product awards and are exported to more than 0/00 countries and regions in the world. There is also a "Silk Museum" near the West Lake, which many foreign friends visit. It spread our silk culture to the whole world.

Silkworm Baby Observation Diary 7 Hey! What is this thing? I approached the silkworm's home and found a strange thing in the corner of the box, which could not be moved and was firmly tied by silk. Look at my little silkworm again. My big silkworm is gone.

My mother ran to me and said, "Your silkworm has cocooned!" "I jumped three feet for joy. You see, its cocoon is very fat, five centimeters long. In order to guard against the enemy's attack, it also tied itself up with spinning silk. Its silk is thin, white and smooth, very beautiful.

All the other young silkworms have grown up, half a meter long. They eat too much now, and they can eat a piece of mulberry leaf soon.

Through the observation these days, I also found some living habits of silkworms. Silkworm babies always sleep with their heads held high and always crawl forward. Whenever I help them clean the room and move from one box to another, they will keep spinning on my hand. The silk they spit is so thin that you can hardly see it, but it is not easy to break.

Last week, my grandmother bought me some silkworm eggs. I put them in a small box and took them to the balcony to bask in the sun. A few days later, several little black silkworms hatched. Silkworm's head and body are all black, curled up like small commas. I quickly picked fresh mulberry leaves and fed them. They all crawled slowly on the mulberry leaves, and their little heads moved. Soon, they gnawed holes in the mulberry leaves.

Small silkworms crawl leisurely on mulberry leaves when they are full. I looked at them, and they looked up at me, as if to say, "little master, thank you for your hard feeding." We should eat more mulberry leaves, grow into big silkworms and weave snow-white cocoons for you. "

A month ago, I got a special' gift' in Chinese class-silkworm baby. After I got these little silkworm babies, I had a lot of questions in my heart: how do they eat? How do you shit? So, I made a careful observation with these questions.

Silkworm baby looks very cute. Its body is as long as a big potato chip, but its head is only as big as a grain of rice. It has two pairs of black patterns like brackets on its back, probably to scare natural enemies. But after peeling, the bracket is gone, and it will take a few days to recover.

It has a small thorn on its tail. When it is in a bad mood or hurt, the small thorn will soften. Silkworm babies have three pairs of chest feet, four pairs of abdomen feet and a pair of tail feet. Its belly feet are used to fix itself, its tail feet are used to hold things, and its chest feet are its real feet, which are used to help it catch food and facilitate it to eat. When you grow up, you will lose your belly and tail feet and become an insect with only three pairs.

The way silkworm babies eat mulberry leaves is very interesting. It first grabs mulberry leaves with its chest and feet, and then raises its head. Like an excavator, it sends mulberry leaves to its stomach in an orderly way from top to bottom again and again. After a while, a mulberry leaf disappeared.

I also found another strange thing when I was raising it: the stool it pulled out was about the same size, like sesame, black and small, solid but a little elastic, with patterns like corn on it. I took a look and found that it was full of mulberry leaf foam undigested by silkworms, and there was a fragrance.

Through so many days of observation, I found that silkworm babies are really selfless. It has worked hard to eat mulberry leaves all its life, just to spin cocoons and let us have warm clothes and quilts to enjoy. I finally understand the true meaning of "Spring silkworms must weave until they die".

Silkworm baby observation diary 10 Silkworm baby has finished eating its mulberry leaves, and I'm afraid it will starve to death. Today, Yan and I went to pick mulberry leaves together. This time is different from last time. I didn't come last time, but I came this time. As soon as we got there, we started picking.

I am responsible for climbing trees and throwing mulberry leaves on the ground. Shang Heyan is the same as me. Soon, we picked a bag full of mulberry leaves. At this time, the businessman said, "hurry home, or the family will be angry." After listening to this sentence, I thought, "Sometimes it still rains." In a short time, I returned home. I ran quickly to the bedroom. I gently opened the box and saw that the lovely silkworm baby was safe and sound. The stone in my heart finally fell to the ground.
