1. Write an essay on observing insects

When the ants walked out of the door, they collided with the "big fireball". The sky was high and far away, clean and pure. Because of the earth's In the reflection, the blue sky also seems to reveal a lovely green color, and pieces of white clouds are floating gently towards the white sails floating in the sea.

I strolled to the corner. There were a few grasses in the corner. Among these grasses, there was an ant hole. I pulled up the grass, squatted down, and looked at the ant's home.

Except for some clay, there is not even a blade of grass in the ant's home, no bed, no tables and chairs, and no household appliances. Some people's entire wealth is grain and ant eggs.

In my eyes, it became a grain of dust, but in the eyes of ants, it must be like a sack of a hundred pounds of rice, because they did not move it easily. Some carried one section on their backs and rested on the other. Some ants carried it away together, and no ant was not walking in a hurry and walking in a hurry. The most interesting thing is when the ants move.

You see, some of them are biting ant eggs, some are holding food in their mouths, some are carrying newly born ants, and some have already transported things to their new homes and returned to move them again. The second time. I watched carefully and found that they were always lined up in a long column, with a big leading ant at the front, probably their "leader".

The long team is like the chain of a bicycle, touching forward one by one, circulating back and forth in an orderly manner. What’s even weirder is: if someone falls behind, or someone gets playful, the partner next to him will go around and gently touch the “little naughty” tentacles with his thick feet.

The naughty guy knew he was wrong and immediately joined the team again. It seems that their discipline is quite strict.

In the blink of an eye, a few hours passed, and the ants’ house was moved, and my parents’ calls brought my heart back. I discovered the life of ants, how proud and happy I am.

Through these observations, I realized that insects are not so stupid. Insects also have the same things that we humans have. You must never look down on insects. 2. Write an essay on observing insects

Ants

As soon as I walked out of the door, I was full of "big fireballs". The sky was high and far away, clean and pure. Because of the earth's In the reflection, the blue sky also seems to reveal a lovely green color, and pieces of white clouds are floating gently towards the white sails floating in the sea.

I strolled to the corner. There were a few grasses beside the wall. Among these grasses, there was an ant hole. I pulled up the grass, squatted down, and looked at the ant's home. Except for some clay, there is not even a blade of grass in the ant's home. There are no beds, tables, chairs, or any household appliances. Some people's entire wealth is grain and ant eggs. It looked like a grain of dust in my eyes, but in the eyes of the ants it must have been like a sack of a hundred kilograms of rice, because they did not move it easily. Some carried one section on their backs and rested on the other, and some ants carried it all together. , not a single ant is not walking in a hurry and walking in a hurry.

The most interesting thing is the ants moving.

Summer is a sultry time. Suddenly I heard the chirping of cicadas. So I went to catch a few for observation.

Cicada, commonly known as "cicada". An insect. The largest cicada is 4-4.8 cm long, with dark brown wing bases. In summer, it cries loudly in the trees and uses needles to make mouthparts to suck the sap. The larvae live in the soil and suck the sap from the roots, which is harmful to the population. The shells shed by the cicadas can be used as medicinal materials. This knowledge is what we generally understand. However, after a few days of observation and information found. I feel even more that everything in the world is wonderful.

For example, regarding the medicinal value of cicadas: they belong to the order Insecta, order Homoptera, and family Cicadae. The skin of cicada is called cicada, which is rich in chitin and isoxanthin, red butterfly adenosine triphosphatase, and is often used to treat exogenous wind-heat and hoarse cough. Sore throat. According to the "Chinese Materia Medica" records, it can also treat rubella itching, red eyes, tetanus, epilepsy in children, and incessant crying at night. It can also benefit essence and strengthen yang, quench thirst and promote fluid production, protect the lungs and kidneys, be antibacterial and reduce blood pressure, and treat baldness. Illness awaits action.

Nutritional value of cicada. Cicada monkey is cold in nature and fragrant in taste. It has the functions of dispersing wind and relieving lungs, relieving fever and calming convulsions. Cicada monkey is rich in nutrients and tastes good, making it a fashionable delicacy.

Cicada body is rich in nutrients, with a dry basis protein content of more than 70%, fat content of about 7%, vitamins and various beneficial trace elements, which are higher than ordinary meat products. It can be called the protein king in today’s food. .

I didn’t expect it, such an inconspicuous thing. So valuable. Even more amazing things are yet to come!

Logically speaking, the vast majority of insects only have a life history of one year or less. The average cicada only has a life history of 3 to 9 years, although there is also a 13-year-old cicada. In the summer of 1979, from Carolina to New York in the United States, countless small dark insects flew out of the ground every night. These were the seventeen-year cicadas. They fly to almost any erected target, such as trees, power lines and buildings. After a while, the male cicadas emit a joyful and noisy cry to lure the female cicadas, marking their 17 years of existence underground after their birth in 1962. , this year came to the ground to hold a "wedding". This is the happiest time for other insectivores. This is a rare feast. However, once the seventeen-year cicada climbs out of the ground, its life is very short. All the insectivores will swarm up to eat these seventeen-year cicadas. If it weren't for their numerical advantage, this cicada would have become extinct long ago. Because this cicada lives underground for 17 years, it has the title of longest-lived in the insect world.

The chirping of cicadas is also very interesting. The cicada that can sing is a male cicada. Its vocal organ is at the base of the abdomen, like a large drum covered with a layer of tympanic membrane. The tympanic membrane is vibrated to produce sound. Since the sounding muscle can expand and contract about 10,000 times per second, the cover and tympanic membrane There is space between them, which can play the role of chirping, so its chirping sound is particularly loud. And can take turns to use a variety of different tones to sing passionately. The female cicada's instrument structure is incomplete and cannot produce sound, so it is a "dumb cicada". It's fun, right?

But for cicadas, the longest time is shedding. A cicada's pupa spends the first two or three years of its life underground, perhaps longer. During this time, it sucks fluids from the roots of trees. Then one day he broke out of the ground and found a tree to climb up based on his survival instinct. After several years of slow growth, the cicada pupa crawls out of the ground as an energy storage body. Its front paws, which are used for digging burrows, can also be used for climbing.

The process of molting begins when a black crack appears on the cicada's back. Molting is controlled by a hormone. The front legs of the cicada pupa are hook-shaped so that when the adult emerges from the empty shell, it can hang firmly on the tree. It is very important that the cicada pupa faces the tree vertically. This is for the normal development of the adult wings, otherwise the wings will develop abnormally. The cicada uses the pupa shell as a base and slowly extricates itself, just like crawling out of a suit of armor. The whole process takes about an hour.

An hour is very short for us, but for cicadas it is the most difficult time in life.

When the cicada's upper body is free, it hangs upside down with its wings spread out. At this stage, the cicada's wings are very soft and they spread through the fluid tubes in them. The body fluid pressure causes the wings to expand. When the liquid is pumped back into the cicada's body, the outstretched wings have hardened. If a cicada is disturbed while its wings are unfolding, the cicada will be disabled for life and may not be able to fly at all.

Look! The simple cicada has so many mysteries. Still interested in exploring your next insect?

Is that okay?

Take a look for yourself. 4. Fifty-word diary of observing an insect

Today I had nothing to do and saw a few snails. I started observing them.

The snail has straight antennae on its head. Its round eyes appear to be on straight antennae. It carries a round and big "house" on its back, and the pattern rolled into a circle is printed on the snail's big "house". It has no legs that can jump around, so it can only crawl forward slowly.

I plan to have all the snails compete in a crawling race, only two tiles apart. The snail's sense of direction was okay at first. But after a while, the snails began to move in different directions. One snail crawled to the left, and accidentally fell down the steps. I ran down quickly, worried about it: Will it die? When I got to the edge of the steps, I saw it clinging to the edge of the steps mischievously. I slowly picked them up, put them in bottles, and put them into the small pool. It was getting late, so we went to bed together. 5. Observe small bugs and write an essay

Observe small bugs

When I was doing my homework after school today, I was working hard to correct the math exercise book. Suddenly, a silver light flashed out of the corner of my eye. However, when I finished correcting the question, I saw, ah! A small insect can no longer fly. It landed on my exercise book. I pushed it in front of my desk lamp and placed three erasers next to it. I wanted to finish my homework and tease it for entertainment. Done, I continue to do my homework. I was writing Chinese while reading it. Suddenly, it climbed onto my yellow eraser. I picked up the yellow eraser, shook it off, and it turned over. When I finished writing a sentence and looked at it, I saw it crawled onto my sand eraser again, so I shook it off again. When I finished writing another sentence, I happened to see a wonderful moment: it turned over from lying on its back to a crawling position. I couldn't help but admire its strength. It climbed up to the desk lamp and headed up the 90° steep slope. It tried several times, but finally it fell over and rolled over. I continued to work, and when I finished writing a sentence to translate, I saw that it couldn't get up, so I gave it a small piece of paper, and it turned it over against the small piece of paper. It still tried hard to climb the 90 °The slope was steep, but I still turned over. Alas~~I continued to write hard. After I finished the copybook, I saw that it gave up climbing the steep slope and switched to climbing the rubber. It seemed that it was still very smart. As soon as it climbed up, I got it down. It landed very steadily this time. It was a skill that I had tried dozens of times. It continued to climb the steep slope. It felt that climbing on rubber was dangerous. It fell down and turned over just like before. I immersed myself in writing again, but when I finished the dictation notebook, it still had not been turned over. It was struggling there. I moved the small piece of paper over to let it crawl on it, but it exerted force and fell to the side. I continued to do English dictation. When I was halfway silent, I took a look, wow! It turned over, staggered forward a few steps, and was blown down by the wind from the electric fan. It continued to work hard, and with a strong effort, it turned over. It climbed onto the piece of paper it was turning over, climbed on it, and stopped moving...

This little bug is too perseverant. If we We are like this little bug when we study, and we are like little bugs when we encounter difficulties, then nothing can stump us! ! 6. Write a composition about observing insects

It was late at night, and the moonlight penetrated through the window and spread all over the floor. I sat alone in front of my desk, letting my tears wet the test paper with pitiful scores.

In this final exam, I fell far short of the expected results. I feel aggrieved, why do I pay so much, but get nothing every time? I blame God for being unfair. Unconsciously, I remembered the scene of reading at night, and the scene of my parents bringing me bread and milk. Why, why, am I really not good at studying?

Forget it, don’t think about it, turn on the light and read the extracurricular books. I turned on the desk lamp. I noticed that the biscuit crumbs on the table were moving. I pushed up my glasses to see clearly. I saw a few ants moving the biscuit crumbs. The biscuit crumbs moved and stopped, as if they were struggling to move them. It was really interesting! I got a magnifying glass and wanted to take a closer look at these little things. I also want to put some "obstacles" in their way. I put the pencil in front of them, and they were about to change direction. As a result, they were surrounded by my pens. Let's see what they do this time! I observed carefully with a magnifying glass. A leading ant climbed onto the pen first, like a commander. Several more ants climbed up one after another. They tried to push the biscuit crumbs over, but they tried several times without success. The leading ant lifted the biscuit crumbs, and the ants behind pushed hard. It took about thirty minutes before the ants finally carried the biscuit crumbs away from the pencil.

I suddenly realized that even such a small ant is not discouraged in the face of setbacks. We humans should dare to face setbacks. I remembered again: Edison’s laboratory was bombed. Faced with such setbacks Edison did not lose his fighting spirit and successfully invented the phonograph in just three weeks; Beethoven was deaf in both ears, which was undoubtedly the biggest setback for a musician, but Beethoven did not flinch in the face of setbacks. He said: "I want to hold the throat of destiny." In this way, Beethoven created the world-famous "Destiny" symphony.

There are winds and rains on the road of life, and there are thorns everywhere. As long as we fight and fight, there will be flowers and applause waiting for us. Celebrities have said that setbacks are a bottomless abyss for incompetent people, but for those who dare to face setbacks, it is a stepping stone to success.

I opened the textbook again, and at this time the first ray of sunlight in the morning shone into the house. Wherever I fell, I got up. I laughed, setbacks, I challenge you, life is more exciting because of setbacks. 7. 500-word essay on observing a small insect Note: It is raining now

This week, the teacher assigned an essay topic about a small insect. Today, my dad and I went to the park to observe bugs.

Suddenly, I found a few ants crawling on the ground. "Dad, there are a lot of ants here," I said in surprise, "Let's observe the ants today. Can you help me find a fly?" "Okay!" Dad went to catch a fly and used a twig to kill the fly. Thread it up, then place the fly where the ants are, and then press the branch where the fly is pierced with stones. After a while, an ant "scout" came. It smelled with its nose and moved its tentacles. Then, it circled the fly a few times and pulled the fly, but it couldn't be pulled, so he Went back into the hole.

I thought he left in despair, but just after a while, another little ant came up, no, two, three... A large group of ants crawled over, and they pulled I pulled and lifted it, but I still couldn't lift it. Because the fly was suppressed by dad with a stone. Immediately, an ant went back to fetch reinforcements. This time, he called "General Big Head". This "general" is twice as big as other ants. It has a big pincer in its mouth and looks very powerful. "Little Ant, what's the matter with you?" "General, the prey outside is too big. We need you to break it down so we can move it." "Oh, come and lead the way!" Little Ant said. "General" was brought to the side of the prey. "General" skillfully climbed onto the fly's back and easily cut off the fly's wings with large pliers. An ant immediately lifted its wings back into its burrow.

Then, the four ants immediately lined up in two columns and pulled the fly's legs straight, "General, cut this leg off quickly!" "Okay", with a "click", the legs were cut off, and two The ant carried the leg away. On the road, one ant said to another ant: "Hey, it takes two people to lift such a little leg? You are looking down on me. You go and do your work, I will do it alone." Just carry it." When I saw this scene, I couldn't help but doubt the accuracy of the ancient saying "One monk carries water to drink; two monks carry water to drink; three monks have no water to drink."

"General" cut off the other wing, head, and tail one after another. After a while, a fly, which was dozens of times larger than the ant, was moved back home by all the little ants.

As the saying goes: "When people are united, Mount Tai can move; when people are scattered, it is difficult to move rice." Today, I only really understood the truth of this sentence after observing the labor process of ants.

Although ants are small, they are always thinking about others. There are good things that can be shared with everyone, as well as their spirit of solidarity and mutual help and perseverance. Compared with us humans, shouldn’t we learn from small things? Did the ants learn something? 8. Observe a small insect and write a paragraph. (About 200 words)

In front of my eyes, the grass has become bigger than ever before, and the grass has become a big forest. A little ant, walking around alone, discovered I found a small piece of bread crumbs. I thought it must be a good chef. It came out to find something to cook. Now it found it, but it couldn’t move it. It turned around and walked back and came to the cave. After a while, the ant The chef brought out a few more porters, and they worked together to move the food in. They will have another sumptuous dinner tonight! I seemed to smell the fragrance of the ants' rice. I wanted to go in and share it with them, but I was afraid of scaring these little elves. The lives of ants are also very regular, and they do their own things: the little ants are here School goes to school, the teacher is teaching, and the teachers and students are so serious and attentive. When the little ants go to school, their parents are working and going to work. Jingle bells... The school bell rang, and the little ants all went home. When they get home, the little ants report to their parents what they have learned in the day. The parents may criticize them or praise them. A little ant that looks very proud, I think it must have got good grades. An ant robber looks fierce. I stopped an ant resident, and the ant police happened to pass by and caught the ant robber. I think the ant police must be very happy because it has done a good thing for the people. The smoke rises in the farmyard, and the dog barks. Called my soul back. I would like to hold your hand and take a walk together in the kingdom of ants.

9. Write an essay about observing insects

Today, I got up early and observed ants in a dry place.

I used a magnifying glass to see clearly. The true face of the ant: The ant's body is composed of three small balls. Its head is relatively large, with two flexible tentacles, its mouth looks like two curved pliers, its chest is a bit small, and six thin and long legs grow on it. Here, the belly is swollen and trailing behind.

I used a red crayon to draw a circle around an ant. The ant suddenly panicked and must be thinking: Oh my God, my Why is there such a red obstacle in front of me? Will it eat me? So, it took a few steps back in fear, but unexpectedly encountered the red obstacle again, and was startled again: I had no choice but to grit my teeth and rush through. It carefully raised its foot and touched the red line. There was no movement, so I stepped forward with confidence and climbed out on tiptoe.

If you can withstand the test of "obstacles", you must not be able to withstand the water. I want to create a " "Flood disaster". So, I poured some water on an ant. It floated up suddenly, struggled desperately, its hands formed a "human" shape, and its "hairs" seemed to stand up. After two or three Seconds later, it was blown to the ground by the wind and stood up miraculously. The life of ants is so tenacious!

I took another piece of bread and put it on the ground to see how the ants carried the food. After a while, a big ant was attracted by the smell. It climbed up and down, looked around, and finally figured it out. Seeing that it was an extra-large piece of milk bread, it quickly crawled home. After a while, the ant came out, followed by a large group of black people. Suddenly, more than twenty ants surrounded the piece of bread. Under the command of the big ants, some ants got to the bottom and prepared to lift the bread; some bit the bread to make it easier to move forward. Perhaps because of consideration The bread was too big, and some ants gnawed some pieces and carried them home first. In this way, the group of ants worked hard in one place and moved the bread into the house step by step. I was dumbfounded.

What cute little creatures, I was a little amazed. When they encountered difficulties, they did not lower their heads and retreat, but fought hard forward and finally won. When they saw delicious food, they knew how to share, unite and help each other, and worked together to move the food. Go home. Aren’t we trying to learn this spirit?
