Recently, a group of lovely silkworm babies have been raised at home.
Silkworm babies are long and look a bit like cabbage worms. It is white all over, with a small head and some thin Mao Mao, and a pair of small eyes. There are three pairs of feet in front of the body and eight pairs of abdominal feet under the stomach. If you touch their bodies with your hands, you will feel soft.
When the silkworm baby just laid eggs, it was black and small, like a strand of hair. I dare not touch them, for fear of crushing them if I use too much force.
Every day when I come back from school, I will take good care of them and feed them mulberry leaves. When young silkworms eat it, it is very interesting. It always eats in the same direction. It will keep chewing and make a "yum yum" sound. Mom said that the sound they made when eating was like a wonderful music.
Silkworm babies can't touch water. If they touch water, they will get sick. Every time I feed them, I will dry the water on the mulberry leaves and cover them directly with leaves. Soon, you will find a head sneaking out of that leaf, which is a hole they have chewed out. So cute! I also like to play with them in my hand. They are always crawling around on my palm, which is very naughty. Silkworm babies are very greedy. They can eat a lot of mulberry leaves every day and go to bed after eating. When you sleep, you will hold your head high and not move.
Every once in a while, young silkworms will shed their skin and grow to one year old, so there are silkworms of one, two, three, four and five years old. When they are five years old, they will spin silk, then wrap themselves up and weave a cocoon. My silkworms are golden silk silkworms and white silk silkworms. The silk of golden silkworm is golden yellow, while the silk of white silkworm is white.
I think sericulture is very happy, because I think silkworm babies are so cute!
Known as the first worm in the world, the silkworm is the treasure of our Jiangnan water town. May is the season for raising spring silkworms every year. Grandma raised two more silkworm eggs this year. As long as I have time, I will help her pick mulberry leaves and feed them to the silkworm babies.
Silkworm eggs were dense black eggs when they were first brought here, so they need to be kept in a heat preservation sericulture room. After about two or three days, the ants hatched from their eggs, black and small, not as big as ants. Because it is too weak, it can only be brushed on the tender mulberry leaves with soft feathers, and the mulberry leaves should be cut into small pieces to facilitate small nibbling.
A few days later, the young ants began to become fat and white, and eating mulberry leaves made it worse. One day, I found the silkworm babies holding their heads high and motionless, giving them mulberry leaves without eating. I was worried that the silkworm baby was ill, so I was busy asking grandma to come and have a look. Grandma said with a smile, you are really making a fuss. Baby silkworm is sleeping. They will shed their skin when they wake up from sleep, so they will grow bigger and bigger. After careful observation, I really found that some silkworm babies were crawling towards their heads, trying to take off their coats. After molting, young silkworms become bigger, whiter and more edible.
More than 20 days passed, and the little silkworm that molted four times was fat in vain. Its body is six or seven centimeters long, with a section on it and a row of small black spots outside, like a window on a train carriage. On the second part of its back, there are two stent-like patterns, from which the future wings grow. Silkworm babies are soft, cool and slippery, and can be eaten very much. When they are quiet at night, they rustle like rain. This is why they are enjoying the delicious fragrance of mulberry leaves.
After another week or so, the silkworm baby will stop eating and cocoon. Grandma took out the prepared straw and built a grass mountain to build a nest and cocoon for the silkworm baby. They climbed the grassy hill and began to spin. It took them more than a day to wrap themselves up and become an oval cocoon. Looking at the snow-white cocoon, I can't help but think of Li Shangyin's famous sentence: The silkworm in spring will weave until it dies. How great the silkworm baby is. Although its life is short, it gives everything to itself without reservation. This life in full bloom leaves an ordinary life track and a colorful and beautiful world!
Some time ago, the science teacher sent us some silkworm eggs to hatch at home. These silkworm eggs are smaller than sesame seeds, round and full of dust. I'm a little skeptical. Can these little guys really hatch silkworm babies?
At home, I put silkworm eggs in cotton, because the science teacher said that silkworm eggs can only hatch at a certain temperature. In the next few days, I went to see if my silkworm baby had hatched after school. Looking forward to the stars and the moon until the fifth day, as usual, I opened the cotton and was surprised to find several small black caterpillars crawling on the white cotton. I cried happily, "My silkworm baby has hatched!" " My silkworm baby has hatched! "I quickly found a small paper box, took a piece of mulberry leaf, carefully hooked the silkworm baby on cotton to the mulberry leaf with a toothpick and put it in the paper box. I can't help worrying again: will such a small silkworm baby eat mulberry leaves?
The next morning, I couldn't wait to open the carton as soon as I got up. I found a few small holes in the light green mulberry leaves, and a little black silkworm lying on the mulberry leaves stretching. It seems that my worry is unnecessary. These little things can be eaten and pulled for a while, which is very healthy!
Under my careful care, my silkworm babies grow up day by day. I found that their dark bodies gradually turned into dark gray, and their brown heads were faintly discernible. They eat mulberry leaves faster and faster, and their bodies are getting longer and fatter. Sometimes I find that they hold their heads high when they are full, as if to say, "little master, thank you for giving us such tender mulberry leaves every day."
Through my personal experience during this period, I think it's really interesting to raise silkworm babies!
Today, my mother and I are going to do a small experiment: What does a silkworm baby look like in a cocoon?
I took out the earliest cocoon, like a golden peanut.
I took out a pair of scissors and cut them in the middle of the cocoon excitedly. Mom quickly said, "Stop it, it will cut the silkworm baby."
I listened and said, "What should I do?"
Mom said, "If you think about it carefully, the baby will definitely figure out how to do it."
I was about to start cutting, but my heart was pounding and I didn't dare to do it. Mother smiled and said, "As long as you are bold and cautious, you won't hurt the silkworm baby." I was relieved to hear that.
Carefully cut a small hole.
I carefully cut the cocoon. Wow! The chubby silkworm baby has turned into a red and yellow pupa, and its body is much fatter and shorter, and its joints are still obvious. There is still a lump in the cocoon when the silkworm baby becomes a pupa.
Back display: the thick end on the left is the head of the pupa, and the thin end is the tail. The body length is only 1/3 of that of a silkworm baby.
It shows the abdomen of the pupa, and the lower part of the picture shows the skin that falls off when the silkworm baby becomes a pupa. Silkworm cocoon is very thin, but this thin cocoon shell is actually woven by a 1500m filament, which is amazing.
I touched it with my hand, and it moved and scared me. I didn't expect it to be alive. It seems to say to me, "Don't hurt me." I put it back in the cocoon and let it become a moth as soon as possible.
Silkworm babies have changed a lot!
Mom's words: I never knew the living state of silkworm chrysalis in cocoon, but today I know that silkworm babies shed their skin when they become pupae. It turned out that the chubby silkworm baby became a thin pupa, and the process of spinning exhausted its physical strength. A temporary rest in the pupa is also to prepare for raising offspring.
Recently, all the students have started to raise silkworms. There are boxes of silkworm babies on the shelf of the bag, which is particularly eye-catching. After class, many people came to watch. I look itchy and plan to buy some after school.
There are several boxes of silkworms in front of the stationery store in front of my house. They are very small, and their colors are different: gray, milky white, light yellow ... and some are slightly cyan. I picked some big gray silkworm babies and put them in the bag. I went downstairs to pick some mulberry leaves, and then went upstairs to put silkworms in the shoe box.
I put silkworms on fresh mulberry leaves, and they immediately smelled the fragrance and twisted their fat bodies to find the edge.
I observed these silkworms carefully. Their heads are wrinkled, like human brains, their mouths are brown, eight short legs are hidden under their huge bodies, and thinner legs are long in front to explore the road. Their bodies are segmented, with a small black dot on both sides of each segment. If you look closely, you can see some tiny hairs and soft thorns on their tails.
Although they are small, they are all real foodies. As soon as they find the mulberry leaves, they will grab the mulberry leaves with their first six feet and start eating in a semicircle. At this time, no matter whether other silkworms climb on them or twist their bodies into an S-shape, they will not pay attention.
I poked one of the silkworms with my finger, and it seemed unconscious. After I poked him a few times, he looked up and shook his head as if staring at me, then slowly adjusted his posture and continued to eat.
I put a silkworm on my finger, and it seems to be frozen stiff. After a while, it groped around. Seeing it climb down, I turned my finger, and it returned to the top, climbed down and turned around again ... After several rounds, it simply stopped moving. I pushed it with my finger, but it didn't hold steady for a while and fell on the mulberry leaf, feet down. Very interesting.
I looked at them and thought: Grow up quickly, so as to catch up with your.
Silkworm rearing 6 Silkworm rearing 6 Spring has arrived, everything has revived, and the mulberry trees in the mountains have slowly grown green leaves. It's sericulture season again. This season, every time someone sells young silkworms at the school gate, students can't help but be curious to buy some to raise at home, and I am no exception. I spent a dollar on 20 young silkworms this year. I prepared a paper box for them. This is their little home. In the first few days, they were really too small, only as big as small black sesame seeds, and they ate very little. A few mulberry leaves are enough for them to eat all day. After about five or six days, it grew to the size of two or three grains of rice, changed from black to light brown, and ate more. They kept eating mulberry leaves from morning till night, as if they could never get enough. Suddenly for a day or two, they lay on the mulberry leaves and couldn't eat. It turns out that they are changing "new clothes"! After the "clothes" were changed, the whole silkworm baby became white and fat. At this time, they ate too much and no one wanted to lose weight. Eating and eating, a small black dung ball is discharged from the tail from time to time, even so it will not stop. After more than 20 days of growth and several times of peeling, they began to "climb the mountain", depending on how they slowly climbed to the corner and upper part of the box and began to spin silk. They "each" occupy a position, shaking their round heads left and right, left and right, and feeling irregular. By the next day, the oval cocoons were basically knotted, some were golden and some were white. However, at this time, we can still see that the silkworm babies are still busy in the cocoon. After a few days, the cocoon is completely silent. I finally look forward to the harvest season. I was shocked when I opened the box. Every beautiful cocoon of mine has a hole, and twenty white silkworm moths are lying at the bottom of the box. It turned out that the lovely silkworm babies inadvertently "turned cocoons into butterflies" and completed the transformation of their lives!
I often think of this poem, but I never know what a silkworm looks like. Until half a month ago, Teacher Yang arranged sericulture in the science class. As soon as I got home, I took my mother to buy silkworm babies. A few days later, the silkworm baby I miss day and night finally came, and I naturally became a silkworm baby.
Go, go, go. I opened the box with great excitement. There are eggs in it. In order to hatch them, I put a lid on them. After the ants came out, we built a home for the little silkworm. With our care day and night, the silkworm baby has finally grown up a lot. One morning, several white cylinders suddenly caught my eye. They crawl slowly and hold their heads high from time to time, just like a few starving little dolls, asking me for food.
Just as I was immersed in the time with the little dolls, the colored feed came. We put the silkworm babies in a big box. In order to make it change color, I soaked the colored feed in water for a while, then carefully coated it on the reverse side of mulberry leaves and finally put it in. In a short time, Silkworm Baby's house became a vivid and colorful picture, decorating the world in front of me.
At school, I saw the silkworm babies in Zhang Hengwei, as if they were mutated and huge. By contrast, my silkworm babies are dwarfed in front of them.
Today, I saw a few of them climb to the corner, and I guess they may be cocooned. So, I concentrated, gently stroked them and secretly separated them. ...
Watching the silkworm babies grow up day by day, I am full of expectation and want to see the moment when they break into moths. I will take care of these little dolls more carefully and wait for them to bloom. ...
