Observe the composition of insects

In our daily study, work and life, we always contact or use composition. With the help of composition, we can vent our emotions and adjust our mood. Then the question comes, how to write an excellent composition? The following is my composition on observing insects for you. Welcome to reading. I hope you will like it.

Observe the composition of insects 1 On this day, He Laoshi asked us to observe ants.

After lunch, we walked out of the classroom. We first came to a place where there were ants, and then took out a grain of rice and put it in front of a big ant. It smelled it first, then stood there, fiddling with its tentacles with its front foot. After a while, we got tired of waiting and took the big ant to other places.

We saw another little ant, so we also put food in front of this little ant. In front of the food, the ant chewed the food with its pincer-like mouth, and then shouted for help. We found that when the ant called for help, it found an ant, touched its tentacles and walked forward. We waited for a few minutes, but it took too long to call for help, so we went to observe another ant.

We came to the lawn and saw an ant with a small personality. As before, we put food in front of ants. The ant is very excited. He walked around the food first, then chewed it to see if it was suitable, and then went to ask for help immediately. Just then, the bell rang and we went to class. After class, we were surprised to find only a little food left.

Ants are really amazing!

This time, I will introduce you to a new protagonist. As soon as you see it, you will definitely think of Cinderella in fairy tales. It's wearing a dark gray dress, but it's just a cloak. As long as it spreads its wings, it will surprise you. It turns out that there is a colorful "dance dress" hidden inside! It is a mysterious visitor to my home-an unknown tramp, so I gave it a nickname-"colorful skirt". The colorful skirt looks like a butterfly, but I think it should be with locusts. Without kindness, it must be a "wolf in sheep's clothing".

The beautiful "dancing dress" of "colorful skirt" is really charming, but if you look closely at its head, you will find that it does not match its "honorific title": there are two jaws with small thorns under a pair of scarlet eyes! Hey hey, isn't that scary enough? There are many colorful dots embedded in its dancing clothes, including red, black, yellow and white, which are really beautiful in the dark blue background, so as long as other insects pass by, it can't wait to show off its "dancing clothes". But at the same time, he is so stingy. Listen, I haven't seen enough. He has packed his dancing clothes. Hey! I can't help it, but don't worry, I'll tell you another little secret-the "colorful skirt girl" can't fly with wings, but usually just jumps. Ha, you see, it is not happy now, and it is still worrying about it.

Today, when my father put on his socks, he shook out a little beetle. He is as big as a thumb nail, his black back is dotted with small golden patterns, and there are two small eyes on both sides of his square head, next to which are a pair of tentacles. It has six legs, the two at the back are the strongest, mainly used to push the ground, and the forelimbs are used for support. Each leg has black fluff and six small hooks at the top.

At that time, he lay motionless on the ground. I pushed it, turned it over and teased it, but it still didn't move. I thought she was dead, so I said to my father, "Throw it away." So dad threw it into the next pot, hey! Unexpectedly, this little thing came to life immediately. It scratched its ankle and struggled desperately. "Ha ha", so it's playing dead. This little thing swims happily in the water. Its front legs can slide separately, like freestyle arms, and the middle group slides 360 degrees, like butterfly stroke. His hind legs are kicking water up and down, but he is not an expert in swimming. It doesn't swim fast at all.

I checked the information. It's called golden beetle. It pretended to be dead not to confuse the enemy, but a nervous reaction, too scared to move.

I've had enough fun. I put it on the windowsill, and its golden armor trembled. Open it slowly. Exposing the black wings inside, suddenly, with a bang, it flew away like a bomber.

On this day, my brother and I observed ants in a dry place.

I saw the true face of ants with a magnifying glass: the body of ants is composed of three small spheres. Its head is relatively large, with two flexible tentacles, its mouth is like two pliers, and its chest is a little small. Six thin long legs grow here, and its belly is bulging and dragging behind.

I drew a circle around an ant with a pen. The ant was frightened at once, and must be thinking: God, how can such an obstacle appear in front of me? Will you eat me? So, I stepped back in fear, only to meet that obstacle again. I was shocked again: I had no choice but to grit my teeth and get through it. It carefully raised its feet and touched the line. Nothing happened, so it took a step with confidence and climbed out on tiptoe. To stand the test of "obstacles", we must not stand the impact of current. I want to create a flood. So I poured some water on an ant. It suddenly floated up and struggled desperately, and its hand became a "human" shape, and its hair seemed to stand on end. After two or three seconds, it was blown to the ground by the wind and miraculously stood up. The life of ants is really tenacious!

What a lovely elf! I'm a little surprised. When encountering difficulties, they did not bow their heads and retreat, but struggled forward and finally won; Know how to share, unite and help each other, and work together with Qi Xin. Isn't that what we should learn?

Today, I sat on the grass again. In the infinite silence, I forgot the time and myself.

My eyes were attracted by a few small black beetles. The space became bigger before my eyes, the fallen flowers became their house, and the thin green grass became their natural umbrella. But just then, an "uninvited guest" (another black beetle) came. I saw the "Insect Guard" leaning forward, lifting the "knife" on his head and slowly approaching the "enemy". Not to be outdone, the "enemy" set up his own "knife", and then eight legs began to run quickly and attacked the "guard". The "guard" quickly changed into a defensive state and retreated a little, as if gathering strength and preparing for work. The "enemy" relaxed at first sight, and he might think: this man is simply weak! You can't take this. I will win this battle!

At this time, it is too late, that is, fast! I saw that the "guard" was like a volcanic eruption, and all the strength, speed and wisdom were revealed at this moment. It gave way to the "enemy" behind it, and it rushed to the "enemy". At this time, it is not like a beetle, but like a wild bison! Then, it used a "knife" to defend, then dodged, and finally hit the "enemy" with a distance of "108,000 miles". I can't help cheering for the "guard" in my heart.

At this moment, I heard my mother's call. I looked at my watch. It was already six o'clock! I bid farewell to the "guard" and this "forest".

Observing the composition of insects 6 Walking, I suddenly saw a dark thing. When I saw it, it turned out to be a spider with a big belly and a thin waist. It's weaving a web!

What a big spider! It is about the size of a dollar coin, its skin is dark brown, and its eight opposite claws hold a round belly. It hung in mid-air and I almost cried out in surprise. Can spiders fly? When I looked closer, I saw it hanging in the air by a long and thin thread. The top of the thread is tied to a branch, and the bottom of the thread is connected with a small hole in the spider's stomach. As the eight paws kept paddling, the line was constantly stretched.

Go all the way, see all the way. Hey! Why are there more and more butterflies here? There used to be a stream called Butterfly Ditch not far away. There are many butterflies drinking and playing in the stream. I am very excited, pulling my mother to dance in the sun like a group of people, and I am intoxicated with this picturesque scenery.

Walking, I saw some dragonflies. Although the wings of dragonflies are not big, they hold up the body of dragonflies like kites. Their eyes are big, like a "pocket" glass ball, which is a bit strange but smart. . . . . . When I looked carefully, a drop of rain fell from the eaves and hit its wings heavily. The dragonfly fell, and just as it was about to pick it up, it flapped its wings again and "stumbled" into the sky. . . . . .

The world of insects is really colorful!

On Saturday, I sat in bed and read leisurely. A bug flies to my book from time to time to "walk". I didn't care much at first, but when I was excited, I dared to fly to my hand. I grabbed it angrily and pulled its wings. To prevent it from crawling over, I covered it with a used transparent plastic cover. Because there is a little plastic in the middle of the transparent plastic cover, I thought, haha, look where you are going, against Lao Zi!

After more than an hour, I rubbed my eyes and put away my book, only to find a black spot on my exercise book. I looked up to the left. Hey, that guy dared to play in my exercise book, and my anger went up to my head. I just wanted to hit it with my fist, but I drew my hand back, because I suddenly had a curiosity. How did you find out? One minute passed, two minutes passed, and three minutes passed. The worm finally made a noise. I saw it climb to the top of the plastic, then to the bottom of a small hole, trying to squeeze out its head, then its body, and finally its feet. I couldn't help pushing it out!

"That's how smart bugs used to escape!" I'm glad to find a good way. But this time, the bug disappeared. Where did it go? Let it go.

In the process of escaping from the bug, I felt its strong and witty side, and it also told me a truth: don't panic when encountering danger, be calm and try to escape. Don't insist on asking for help when you are in real danger. When in danger, the only person who can help is himself.

This afternoon, my father and I went to the balcony to observe insects. I was so happy that I quickly brought a magnifying glass and wanted to take a closer look. Suddenly, I found a little ladybug crawling on a green leaf! Excited, I quickly grabbed a magnifying glass and observed it carefully. I tried to touch the black, red, black and red shells of ladybugs with my fingers. As soon as my finger touched the ladybug, she turned to face me, as if to say, "Huh? Why are you bothering me? " I burst out laughing. I am very interested in insects, so I went to look for insects on the leaves of Anthurium. I did find a dragonfly. I knew nothing about dragonflies, so I went to my father who knew something about insects. My father and I said, "Dragonflies are small insects, such as mosquitoes, which eat specially." . . . "I don't want to hear my father say these words again, because he and I have already said 100 times! Because I didn't listen to what my father said, I took two empty paper cups, covered the dragonfly with one paper cup, and then connected the dragonfly in the first paper cup with the other paper cup. I locked the dragonfly in a cradle without oxygen!

My father saw my every move and said, "Hi! You can't catch dragonflies for fun! Dragonflies are beneficial insects! " After listening to my father's words, I was so ashamed that I immediately opened the paper cup. Dragonfly jumped out and glared at me, as if to say, "Damn child, why did you lock me up?" Am I interesting? "I murmured," I'm sorry, little dragonfly. "

This observation makes me think that insects are actually very interesting!

Insect observation composition 9 says that ants can lift things dozens of times their own weight. I want to do an experiment.

I took some biscuits and ran downstairs. I found an ant hole and found many small ants busy going in and out. It turns out that the ant is carrying a dragonfly. I saw that some of these ants bit the dragonfly's head and some bit the dragonfly's tail. They all tried their best to bite, pull, push and push. This "monster" was pulled up, and I was shocked that such a small ant could lift such a heavy thing. I quickly divided the biscuit into three parts and put it next to the dragonfly. I saw other ants swarming, biting the biscuits into pieces smaller than the ant hole, carrying them in twos and threes and moving towards the hole. I finally believe that black and thin ants really have such great strength. Also let me understand a truth, unity is strength! Ants are a united group.

How do ants communicate with each other? How does it eat food? Through my observation, I found that the ant's head and ass are very big, but its waist is very thin. They have a pair of "big clips" on their heads, which are their mouths to eat and self-defense weapons, and a pair of tentacles on their heads, which are their communication organs. As long as you meet your partner, touching your tentacles is to say hello or send a message.

Through my experiment and observation, I found some secrets of ants, and I gained a lot. I believe that as long as I observe things around me with my heart, I will discover more secrets and learn more knowledge.

A few days ago, I went to my grandparents' house to play. I read a book at my grandparents' house for a while. After dinner, I told my grandmother that I wanted to go downstairs to play for a while and see if I could meet my long-lost friends. After grandma agreed, I ran downstairs in one breath, hoping to see my good friend as soon as I rushed out of the door. I didn't meet my friends when I walked in circles in the community. When I was depressed, I suddenly saw several dragonflies flying in the air by the central lake. I walked gently and found two beautiful little dragonflies quietly landing on the lotus leaf by the water. They climbed there quietly and didn't even notice that I was peeking at them.

Dragonflies are slender, slender, soft and light. Dragonfly's head is round, with a pair of prominent jewel-like eyes and an iron pliers-like mouth. Next to the head's body, there are two pairs of tulle wings on the body, six tapering legs under the body and a bamboo tail behind it, which is very beautiful.

Dragonflies have many colors, including yellow like gold, blue like diamond and green like emerald. ......

Dragonflies fly like skilled drivers and glide in the sky. There are high and low, fast and slow when flying. When a small flying insect is found, it will dive down.

Dragonflies skimmed over the water, like vigorous Chun Yan, gliding in the air, like fierce eagles.

I like dragonflies very much, especially when they are flying in the air. They seem to be still, which really makes my eyes reluctant to leave these lovely little things.

Observing the composition of insects 1 1 ants, we all know that there are thousands of them, which can be seen everywhere.

There are three kinds of ants: red ants, termites and black ants. Black ants are very hardworking and have food every day, while lazy red ants often attack black ants and take things away, but black ants dare not resist. Why is this? It turns out that the red ant has two big and long "fangs", and the black aunt is particularly afraid of them, so the red ant threatens the black aunt to take things away. So adult black documents are slaves of red ants.

Termites do not often appear, which is one of the four pests. Their main food is wood. As a result, a lot of furniture was damaged: either it was bitten "big and small" or a foot was missing. All the soldiers were defeated, but no trace of termites was found, so termites were also called "invisible killers".

Ants are also the leaders of animal Hercules. He is muscular and flexible. The heaviest thing is three times its weight. If it's too heavy, greet your partner in a unique way and work with your new partner to raise it back to strength. When it comes to ant holes, if you think they are only 10 cm in size, you are all wet. The ant cave is shaped like a castle, with different sizes, but it is consistent with the style of the castle. Perhaps, there are some unexpected things hidden in it!

This is an ant. Do you like it?

Today, I lie on the edge of the grass again, forgetting the world and myself in infinite silence. In front of my eyes, it has become bigger than ever, and the grassland has become a big forest. A little ant, walking around alone, found a crumb. I think it must be a clever cook. He came out to find something to cook. Now he has found it, but he can't move it. He turned and walked back to the cave. Soon, the ant chef brought out some porters. They worked together in Qi Xin to move the food in. They had a big dinner tonight!

I seem to smell the rice fragrance of ants. I want to go in and share with them, but I'm afraid of scaring these elves. The life of ants is also very regular. They are doing their own thing: the little ants are at school, the teachers are teaching, and their teachers and students are so serious and dedicated. When little ants go to school, their parents are working and going to work. Jingle bell ... the school bell rang and the little ants all went home. When they get home, the little ants report their day's study to their parents, who may criticize them or praise them. A little ant who looks proud, I think it must have done well in the exam. An ant robber fiercely stopped an ant resident, just as the ant policeman passed 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. Smoke rises in the farmhouse yard, and the barking of the puppy brings my heart back.

I want to take your hand to the ant kingdom for a walk.

Observing the composition of insects 13 In the evening, when I went home, I came to the community. In the corner of the community, there is a dry meadow. Many insects live in the grass. I came to the grass and turned the ground. I'm surprised. Thousands of ants live here. They add up to as many as a calf. I watched carefully with a magnifying glass. It turns out that the body parts of ants are like this. The ant has a big head with six feet and eight feet. The ant's ass is very small, like a round grain of rice. It has a lot of hair, many colors and many varieties.

I put some ants in plastic bags to see how they can climb out together. One by one, ants drill plastic bags into small holes with two sharp and big teeth, and the holes become bigger and bigger until they become a hole. Ants come out, unite and cooperate, help each other, pull plastic bags into the soil and settle down. I have to admire this scene! The ants let the fattest and biggest ant king live in a plastic bag and told the ants that it was a warm and comfortable new home. There are more and more ants, and I see them declare war on caterpillars. I thought: It's incredible that such a small ant can beat such a big caterpillar. The ants are United and aggressive, and the caterpillar is exhausted by them. What surprised me even more was that they actually lifted the caterpillar and slowly moved to the hole. Although it was slow, they didn't give up. What's more interesting is that they take turns carrying it, as if there is a division of labor: leading the way, encouraging ... After a while, the ants carried the caterpillar into the hole and shared it with everyone. A caterpillar can feed ants for a long time.

It was getting late, so I went home with my bag. By observing the behavior of ants, I learned that unity can overcome all difficulties.

Observe the composition of insects 14 Late autumn evening, quiet and peaceful, doing nothing, wandering aimlessly alone in the green belt of the community. I stood under a big tree and found a black spot moving slowly up at a glance. I looked intently: Oh, it's a black beetle. I thought, "since it's so boring, let's play with him."

I picked up a twig and was about to lift the beetle down. Unexpectedly, it suddenly shrank into a ball and fell to the ground vertically. I thought he was going to run away, but I didn't expect it. He fell to the ground, motionless. Over time, it is still rolled into a ball and indifferent to the world. I was a little unwilling, and on a whim, I insisted on seeing what tricks he played. So, I squatted down slowly and picked it with a small stick. Ah, it's a big deal. It broke its leg. But what about him? But I don't seem to know, just keep going. I was shocked and thought, "Is he dead? Why did you not respond? "

Curiosity drove me to sit down and look down.

As time went by, 10 minutes later, he finally responded. Many things happen. It slowly stretched out its stump, limped and trembled, and stood up slowly, as if it had just found a leg missing.

I'm weirder. I can't figure it out. For a long time, I gently pointed my finger at it, and the scene appeared again: he was lying on the ground, motionless. This time I fiddled with it for a long time, and it seemed to know my mind and didn't move. Is he dizzy or dead? I persisted and decided to find out. I flew home and searched on Baidu. It turns out that "playing dead" by insects is actually a temporary shock. When insects are stimulated by the outside world, their muscles will contract involuntarily, thus losing consciousness. This process usually takes several minutes to regain consciousness.

Only when you explore will you find out.

One day, my good friend and I went to catch crickets. We found a cricket hole, but it was too small to reach. We had to turn over the slate and caught four crickets at once.

The next day, we went to catch cricket with a cricket master, and he also found a cricket hole. So he told us to get the bottle, fill it with water, and then fill the hole with water. I took a small bottle of water and poured it into the hole, but the water was soon drained by the hole. Really as good as the text says. But after a while, someone poured a bucket of water on it, and the well-drained hole also poured out. Later, he gave it to me. When I brought cricket home, I wanted to observe it carefully, but it was dishonest, so I grabbed its tentacles and let it fall. It is much more honest. I seized the opportunity to observe it carefully. Its body is black, its wings are thin, its thighs are strong, and there are small hooks on it. I know I sing with my wings and breathe in with my stomach. I named it "Black Overlord" and "Golden Rooster Independence" because it has only one leg. Once I found "Golden Rooster Independence" chasing "Black Overlord", who was bitten and ran around.

I heard that crickets are pests because they eat leaves. But I once caught a cricket and put it in a bottle. At first, there were many aphids in the bottle. Then I didn't feed it for a week, and it was still alive. At first, I didn't know why. Later, it was found that all the aphids were eaten by cricket. Cricket is really an interesting insect
