Silkworm Diary 1 There are many silkworm babies in my family. Every time they shake their heads, they seem to say to their owners, "I'm hungry and want to eat." Every time the mulberry leaves are placed next to the silkworm babies, the silkworm babies immediately creep onto the mulberry leaves and eat them with relish. It will be finished soon. They eat quickly. When you are full, the silkworm baby begins to play. They squirm like earthworms. It's so cute.
Silkworm babies eat mulberry leaves but spit out precious silk. Therefore, I expect them to grow up quickly and spin early.
Silkworm Diary 2 In the early morning, the sunshine shone 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, and it is motionless, as if thinking about where spinning is more comfortable.
Three days later, I woke 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!
The third article of Silkworm Diary "Great! I have ten! " "Yes, I have! ……"
Huh? How come our class is so busy! Oh, it turns out that many students in the class have adopted silkworm babies. I also have 28! I used to envy others for having silkworm babies, but now I don't have to envy others. Don't mention the happiness in your heart. I feel my heart will fly out of my throat!
I happily put the ants and silkworms in a paper box and brought them home. When I got home, I immediately opened the box and saw that some mulberry leaves were dry. I quickly took out some fresh mulberry leaves from the refrigerator and cut them into thin silk with scissors. Then I gently picked the silkworm babies on the tender mulberry leaves with a brush and let them eat them. Looking at this lovely silkworm baby, I wonder if the silkworm baby will only eat mulberry leaves all his life. So I went to ask my mother, and she said that silkworm babies don't always eat mulberry leaves, and they have to molt five times ... "So, mom, how can silkworm babies molt without hands?" I asked inexplicably, "Hmm …" My mother couldn't answer for a while, so I had to "search" on the Internet. I am very happy to know how the silkworm baby sheds its skin through online search.
But I still have many questions: For example, do silkworm babies only eat mulberry leaves? If you eat other leaves, will you still spin silk? What should I do if the silkworm baby is sick? Go to the pet hospital for an injection? Where will the silkworm baby live more comfortably? Is it an iron box? Wooden box? Carton or plastic box ... in short, I want to know all the knowledge about silkworm babies in one breath!
Sericulture Diary 4 Recently, students in our class began to raise silkworms. I still have five silkworms, all of which are fat for nothing.
I remember that Monday, I just bought five silkworms from a small shop. They are so dark and small that I dare not touch them, for fear of accidentally crushing them to death! Seeing that all the students around me are raising silkworms in vain, I made up my mind to raise silkworms in vain.
I feed them on time every day, and they can eat mulberry leaves quickly. The days passed day by day. One day, I found one of the silkworms suddenly bent down and stood motionless. I was anxious and afraid, so I called the sericulture king in our class and asked a question. She said to me, "Don't worry, this silkworm is going to shed its skin. Look at his mouth. It was dark, but empty. He needs to change his skin. " I am relieved now.
Now all my silkworms are white and fat. Eating mulberry leaves is quick. Soon, they will become moths. ...
Silkworm Diary 5 In science class, the teacher brought two young silkworms to each of us and kept an observation diary. I looked at those two black bugs and couldn't believe that they would eventually spin cocoons.
We share the task of raising silkworms with our mother, and we have made great efforts to collect fresh mulberry leaves for them. Every day after school and work, we all rush to feed them. Although silkworms are small, they can eat well. In a blink of an eye, half a mulberry leaf disappeared, making a rustling rhythmic sound. Gradually, the young silkworm grows up day by day, and its body gradually turns white, thicker and longer. I found that there is a difference between two young silkworms, one is obviously smaller than the other. I was puzzled, so I asked my mother what was going on. My mother thought about it and said, "Maybe one is picky about food and the other is not picky about food." Finally, one day, this picky little silkworm died. Nature is like this, and those who are eliminated are the weak and helpless. There is only one baby silkworm left, and I am a little sad: "After the young silkworm spins and cocoons, it becomes a pupa and finally a moth. Two moths gave birth to new silkworm babies, but the moths will soon die. " I was depressed. My mother said softly, "Yes, silkworms, like any animal, can't escape the fate of death." Mother comforted me not to be sad. We can also raise two more silkworms and let them continue to breed.
Silkworms can eat more and more, feed them several times a day, and get fatter and fatter. I told my mother, look at its silkworm excrement. If it turns green, it will spin silk soon, and it will spin silk with its head held high all the time. My mother praised me for knowing more.
One day when I came home from school, I still went to see silkworms. Ah, it spun silk, just as people say, its head kept moving, and golden silk surrounded itself bit by bit. Dad said, "Don't disturb it, let it vomit slowly." When we watched it after dinner, an oval cocoon formed, and I vaguely saw silkworms spinning in it. I just understand why it can eat so much before it rotates. Just for this moment, it is constantly accumulating strength. The next day, a golden oval cocoon was made, and the silkworm waited quietly inside, first pupating and finally becoming a moth.
Last night, the moth finally broke out of its cocoon. It completed its mission with its snow-white body and snow-white fluff, which can also be said to be its life. This really fulfilled a human saying: "Spring silkworms must spin until they die". I had a strange dream at night, dreaming that I had a pair of beautiful wings flying around the garden!
At the beginning of school, the science teacher gave us tools for school, and there was a small bag of silkworm eggs in the bag.
The teacher told us that silkworms reproduce with eggs. We are required to observe silkworm eggs carefully and tell us that silkworm eggs will hatch into young silkworms at suitable temperature and humidity.
Silkworm eggs are brown and look like sesame seeds. They are about 1 mm wide and about 0.5 mm thick. The outer layer of silkworm eggs is a hard eggshell with yolk and serosa inside. Embryos in fertilized eggs constantly absorb nutrients during development and gradually develop into ant silkworms, which crawl out of the eggshell and turn white or light yellow after the eggshell is empty.
On March 22nd, the silkworm eggs hatched into young silkworms. When a silkworm hatches from an egg, its body is brown, small and hairy, and looks a bit like an ant, so it is called an ant silkworm. Ant silkworm is about 2 mm long and 0.5 mm wide.
Ant silkworms eat fresh and tender mulberry leaves, eat slowly and less, and can put less mulberry leaves; Water drops on mulberry leaves must be dried before they can be used to feed silkworms, otherwise silkworms will get sick after eating them.
Yesterday, Miss Huang gave each of us a box of silkworm babies. I have twelve little silkworms. They are all three-year-old silkworms. Silkworm baby's body is white, with eight small spots on each side. Their heads and bottoms are light yellow. They have five feet. Silkworm baby's body feels smooth and comfortable, as smooth as baby's skin. I thought to myself: Silkworm babies are so cute! I'm so happy!
Silkworm babies eat quickly. Last week, I chose a big mulberry leaf for me. I thought it was enough for them to eat for two or three days! Unexpectedly, when I changed the "room" for the silkworm baby this morning, I found that the mulberry leaves put in yesterday, and the silkworm baby ate very little. I can't help it I put another mulberry leaf bigger than yesterday. Who knows, when I came home from school, I was surprised to open my mouth into an "O" shape: mulberry leaves were actually eaten up by silkworm babies and replaced with a lot of silkworm excrement! I think: Silkworm babies eat too fast! Come on for dinner!
I found that silkworm babies eat mulberry leaves in circles and their heads are very flexible. It has to eat once every time to move its body.
I like sericulture!
