Detailed description of ingredients of mulberry leaves eaten by silkworms 1

Oh, I see! I am very excited and proud that I have uncovered this doubt.

Once after school, I saw someone selling silkworm babies at the school gate. How cute! Itchy in my heart, I pestered my grandfather to buy some. At my request, my grandfather finally agreed. I bought six happily and brought back some mulberry leaves.

When I got home, I didn't have time to put down my schoolbag, so I was anxious to establish a "home" for the silkworm baby and observe it. Silkworm babies chew mulberry leaves under their mouths and make a rustling sound like autumn rain. How interesting! At this time, grandma came over and said, "Silkworms should eat more mulberry leaves so that they can spit out their dead cocoons." "'Silkworms feed on mulberry, so they can become silk'? Can I eat other leaves? " I feel very confused, so I want to solve the mystery myself.

At first, I found two cartons and divided six silkworm babies into two groups (3 in each group). Group A fed mulberry leaves every day, while Group B fed needles that looked like mulberry leaves every day and observed them every day.

On the first day, the silkworm babies in group A ate mulberry leaves as usual, but the silkworm babies in group B didn't seem to adapt to acupuncture, and nothing happened. I'm so anxious that I don't even eat rice, let alone spin cocoons. The next day, the silkworm babies in group B finally began to eat mulberry leaves. I'm relieved, but I'm still a little worried: will silkworms spin cocoons even if they eat other leaves?

As the days went by, the silkworm babies in group A began to spin cocoons, while the silkworm babies in group B remained motionless. I was a little discouraged. Alas, it seems that silkworms are born to eat mulberry leaves! But after a few days, the silkworm babies in group B also spun silk and cocooned! I was so excited that I jumped and jumped with joy. It seems that it is not "silkworm feeds on mulberry, so it can become silk"!

But why is this? Curious, I immediately checked the relevant information: it turns out that there are attractive substances in mulberry leaves and substances that can help silkworms swallow, which have nothing to do with spinning cocoons, so silkworms can spin cocoons when they eat other leaves. But "silkworms don't eat mulberry, and their achievements are the same as others." If other leaves are fed to silkworms, even if they are willing to eat them, they will easily get sick and cannot reproduce normally. Therefore, it is suggested that students still use mulberry leaves as silkworm babies.

Nature is colorful and mysterious. As long as you observe carefully and think positively, you will certainly get something!

In the summer vacation, my father gave me a "big gift"-five lovely silkworm babies. I am very happy. They are all white and fat and very active. It feels cold and soft.

Silkworms do, but we can't let them starve! So, I decided to go to the park with my father to pick mulberry leaves. As soon as we entered the park, we saw several mulberry trees. My father and I went in to pick mulberry leaves. I am both happy and scared, because there are many spiders and cobwebs on the leaves. I am most afraid of spiders, but my father encourages me to say, "Be brave, there is nothing to be afraid of, don't worry." Although my father said so, I still feel uneasy. I finally got up the courage to go there for my silkworm baby. With the cooperation of our Qi Xin, I picked a lot of big and green mulberry leaves, thinking that silkworm babies can eat enough, and I am happy for them.

When I get home, I wash the mulberry leaves with water, so as to keep them fresh and clean. I gently remove the silkworm first, then tear the mulberry leaves and put them in a box, and then gently pick them up and put them on the arranged mulberry leaves. When they saw the delicious food, they immediately opened their mouths and ate it with relish. In a short time, a big mulberry leaf was "wiped out" and only the stem was left.

I kept it for a week, and under my careful care, the silkworm grew up a lot and its body began to turn yellow slowly. My father told me that they were about to start spinning. I am really looking forward to it! I really want to see how they spin silk. One silkworm looks unhappy and is not interested in fresh food. I knew it was going to start spinning, so I gently took it out and put it in another empty box. I saw it look up, glance left and right, and constantly spit out thin white silk from its mouth, trying to wrap itself up. Maybe this is called "tie yourself up"!

When I got up the next day, I couldn't wait to see it. To my surprise, it has cocoon, and it is yellow, indicating that it is not a silkworm, but a colored silkworm. Even so, I am very happy. Over time, the remaining silkworms are spinning cocoons, including yellow cocoons and white cocoons.

After another seven or eight days, they became silkworm moths, laying dense eggs on the paper already prepared. I carefully keep my eggs like sesame seeds, expecting them to start a new life journey in the coming year.

People often say that "silkworms in spring will weave until they die." Silkworm gave everything to mankind, leaving a magnificent place for the world. We should learn from this selfless dedication of silkworms.

Spring has come and the flowers in the field are in full bloom. I don't know when my little silkworm came out of the egg. I saw a few black ants crawling around there, and some were trying to climb out of the bitten silkworm eggs. After 40 minutes, the children who have come out can only eat, only to see their heads raised-looking around, as if waiting for me to feed them. I brought some tender mulberry leaves, and then picked silkworms onto the leaves like little ants with hairpins.

A month later, the silkworm baby is more than an inch long, much cuter than the newborn ant. Look at their chubby bodies and white You Lan. It's really fun to wriggle around Their mouths used to be small, but now they can open wide. At this time, silkworm babies eat much faster than before. A big mulberry leaf soon disappeared in their mouths. When eating, there is still a rustling sound. If you close your eyes, you will think it's raining!

After a few days, the silkworm suddenly stopped eating mulberry leaves. Move slowly with its soft body and find its' home'-a fixed corner. Then I began to spin silk, and saw the adult silkworms hold their heads high and swing slowly and endlessly, as if there were endless silk threads in their bellies. When it is completely surrounded by silk, gradually, the cocoon shell is formed, and some cobweb-like silk is wrapped around its home.

They don't move every day. Suddenly one day, there was a small hole in the silkworm chrysalis, which was very strange-it was obviously a complete cocoon. The mouth of the cave slowly expanded, and a furry head struggled in it. I saw it desperately sticking out its tentacles and using all its strength to expand the hole, but it still didn't help. It has been working hard for a day, and I have no patience to wait, but it keeps trying to break free from the cocoon. From time to time, I see the cocoon move slightly, that is, it tries its best to lean out of the body. Suddenly, one of its wings magically popped out, and then it was very relaxing to watch it crawl on the cocoon exhausted and pull up the other wing with all its strength. I don't know where I got the energy. Maybe I'm finally relieved. It suddenly flew to the window. I silently congratulated it in my heart:' You are great! You finally got your freedom through your own efforts! "You can survive on your own!" Later, many silkworm moths came out one after another and danced by the window. I prayed silently in my heart:' I hope they can keep their babies and live happily according to their own ideas ...'

Silkworm's life is short, but it has not given up every opportunity. For me, the road of life is still very long. I want to add luster to my life with the encouragement and support of teachers and parents like silkworms!

Once, I saw a vendor selling silkworms. As a result, the door of time opened, memories flowed back, and my thoughts stayed on one thing in the second day of junior high school. ...

Sunlight spilled into the paper box and shone on the silkworms. Its snow-white body is crystal clear in the sun. It has brown spots in front of its head and a lot of sticky hair on its feet. It's chubby and very cute! In order to make it look special in the dark, I made a small mark on its back with a luminous pen. It's green, shiny and interesting!

The carton where the silkworm baby is located is on the balcony, and it is sunny. The silkworm baby is lying on the box in the sun. Its back is up, its body is slightly contracted, and it is very enjoyable, just like spending a holiday in Hawaii.

Silkworms are so greedy that they ate up a large piece of mulberry leaves in less than two minutes. It eats funny, with its body sideways, its two front feet clutching mulberry leaves tightly, and its head tilted, as if it were afraid of being snatched away. It really makes people laugh!

What impressed me most was the cocoon formation process of silkworms. If you don't eat or drink when you cocoon, just find a corner and start spinning. Silk is slender, liquid at first, and then it condenses into solid silk when it meets air. It just keeps vomiting. About two days later, the green light disappeared and the silkworms began to cocoon.

I watched it with great interest at noon these two days. Maybe I was tired of watching it and fell asleep at my desk. In my sleep, I saw a silkworm cocoon and turn into a moth. It flew to grandpa's lighter and just touched it, it fell. I cried. I scolded it: "smelly moth, rotten moth, why do you want moths to throw themselves into the fire?" Then you are dead! " Loud noise ... "

I was awakened, and my face was wet when I woke up. I went to the silkworm and saw that it had cocooned and lay there quietly. I carefully took the cocoon out of the dense silk and looked carefully to see when it could break into a butterfly, but two days later, it didn't move at all. I am tired of waiting. I did a very stupid thing. I picked up scissors and cut a small mouth on its head, so that it can quickly become a moth. While I was waiting anxiously, grandma came over. She looked at the cocoon in surprise, then touched my head and said kindly, "Yiyi, how can you cut it?" It will die like this. In fact, most silkworms can't be moths, only a few can succeed, and it's no use doing so! Silly boy, do you understand? "I nodded, puzzled, and deeply regretted the stupid thing I did.

"Silkworms will weave until they die in spring, and candles will drain the wick every night." Through raising silkworms and the teacher's tireless teaching for many years, I really understand the truth contained in this sentence.

Last night, an earth-shattering thing happened in our family-I fed silkworms. Everyone will definitely say, isn't it just feeding silkworms? What's the big deal? However, for me, this is a terrorist incident.

Since the science teacher asked me to raise silkworms, my father has contracted to raise silkworms. Every day after dinner, dad will "go to work" on time. But last night, because my mother's hand was scratched, my father went on strike to wash the dishes, and no one changed mulberry leaves for the silkworm. Dad saw me standing beside him all the time and asked, "Did the science teacher arrange for you to raise silkworms or did Dad raise silkworms?" I am embarrassed to stick out my tongue and walk away.

I opened the box for raising silkworms, and all the mulberry leaves had been eaten by young silkworms, leaving only a few thin petioles. The young silkworms hold their heads high, as if urging "Little Master, give some mulberry leaves to eat quickly!" I really want to feed them mulberry leaves, but the science teacher said to clean the little silkworm's room before feeding them mulberry leaves. I really dare not touch the soft little silkworm! I invited our science teacher, mom, both hard and soft. Yes, my mother is also a science teacher. Mom asked me to watch next to her first. I saw my mother gently take out a small silkworm with long sticky silk and put it on the fresh mulberry leaves prepared in advance on the coffee table. The little silkworm shook her head at once and ate like a hungry ghost. At this time, my mother's cell phone rang unconsciously. My mother asked me to take out the remaining silkworms first, then pour the dirty things in the silkworm box into the trash can, and finally put the silkworms in the box, just like she did just now. Say that finish turned and walked into the room to answer the phone.

I looked at those soft and fleshy "caterpillars", but I still didn't dare to do it. I wanted to clamp silkworms with tweezers and change mulberry leaves myself. My mother joked that the silkworm's skin is very tender, and it will hurt or even die if you accidentally use tweezers. This time, I finally got a chance to do it. While secretly looking back to see if my mother had come out, I carefully took out all the young silkworms with tweezers, and it was done. After cleaning the silkworm box, I was just about to put the little silkworm back in the same way, and my mother came out. I'm going crazy, and I have to pretend I'm not scared at all. Trembling, I picked up a little silkworm, and the little silkworm who left the mulberry leaves immediately raised her head to protest. I screamed at once, and the young silkworm was thrown far away. My mother was scared when she saw my tears, so she quickly came to comfort me and helped me put the remaining silkworms back safely in the silkworm box. However, it was leaked that I caught silkworms with tweezers.

Watching the little silkworm quietly eating mulberry leaves, I thought to myself, how could a man as big as me be scared by a little silkworm? I must not be afraid of it tonight!
