One day, I found a mantis on my way home from school. Mantis disguised as a green leaf and lay motionless on the stem of a small flower. If you look at mantis from a distance, it is like a green leaf in a small lace, which can't be distinguished. After a while, a moth flew in and happened to fly on the lace green leaves disguised as mantis. Mantis flashed two big clips and caught the moth firmly.

Seeing this scene, I was shocked. A question flashed through my mind: why can mantis catch bugs on its back so quickly? So, I went home with this question, looked up the relevant information of mantis, and learned that mantis belongs to insects, with large volume and yellow-brown, dark brown or green color. The head is triangular, the compound eye is big and the corner of the eye is slender. Seeing this, I finally know that mantis can catch insects on its back because its compound eyes are on its head, and it can quickly observe the instantaneous changes of things on its back and make quick responses.

If we imitate the special biological structure of mantis and invent a robot with flowers on its back, eyes on its head and four clips, the flowers on its back can attract pests, and the eyes on its back can observe the situation on its back in time. These four clamps move quickly and flexibly. When pests appear, they kill them immediately. Then, put it in a flowerpot, and the worms will become fertilizer for the soil after rotting. How nice it would be!

In fact, human beings have made many achievements in bionics. The creatures in nature are really good teachers and friends of human beings!

Mantis preys on owls. Convex-eyed owl vs thin-winged mantis I think: What happens if a convex-eyed owl meets a thin-winged mantis?

So, I analyzed the fighting capacity and lethality of the convex-eyed owl.

I caught an owl with swollen eyes.

I also analyzed the fighting capacity and lethality of the thin-winged mantis.

I caught a thin-winged mantis.

Thus, a great war was staged. The convex-eyed owl first pounced on the thin-winged mantis and threw it to the ground. Later, it began to bite. People who like the thin-winged mantis hope that the thin-winged mantis will win, but the current situation is strong for the convex-eyed owl. Then, the convex-eyed owl began to bite its five livers and six internal organs. After that, the convex-eyed owl began to bite its five livers and six internal organs.

Now it is announced that the convex-eyed owl has won.

Thin-winged mantis is deadly.

The convex-eyed owl is amazing!

A 300-word composition about mantis mantis has an extremely sharp broadsword, which is very powerful.

Mantis has a special shape, a triangular brain, big eyes, a thin neck and green wings.

He dressed like a general all his life.

Because mantis loves to catch flies, mosquitoes, flying insects and other insects, it likes to haunt the grass.

Its big green clothes make insects mistake it for big grass. Once an insect approaches, it will quietly approach and then take the initiative to attack.

A pest was eliminated in a short time.

Mantis is a beneficial insect in the human world, but it is also a great warrior and general in the insect world.

...

Extract 300-word mantis from the mantis in the Book of Insects. But when the poor locust moved to the point where the mantis just touched it, the mantis immediately used its weapon mercilessly, hit the poor creature hard with its powerful "palm" and pressed it hard with those two saws.

Therefore, no matter how doggedly the little prisoner resisted, it was of no help.

Next, the brutal demon ghost winner began to chew his booty.

Of course it will feel very proud.

In this way, treating the enemy like autumn leaves is mantis's unchanging creed.

[Appreciation] In the author's simple pen, a serious academic work, such as a beautiful essay, readers can not only gain knowledge and ideas from it, but reading itself is a unique aesthetic process.

In this clip, the author focuses on the action of mantis, vividly showing readers a scene in the tiny insect world, which not only embodies the bravery and fierceness of mantis, but also expresses the author's praise for mantis and love for life, and subtly reflects some characteristics of human beings by using insects.

Observing the composition of mantis Observing mantis Yesterday, I saw a mantis. This mantis should be a larva, with six feet and long tentacles. The most prominent thing is its half-moon brown eyes, its wings seem to be injured, and its whole body is khaki.

When mother caught it, it seemed frightened and flew away.

But I didn't fly far, so my mother arrested me and showed me. It was the first time I saw mantis in real life, so I was a little scared and kept my distance from it.

I saw that mantis's front paws were like sickle, which was its weapon to attack the enemy.

Mom said let it go, and I nodded.

Mother let it go, and I saw mantis's six legs climb up the tree quickly. I don't know whether it was a bluff or a thank you for letting it go with its front paws.

I have a question, that is, when I read Parr's Insect, I said mantis can fly 2-5 meters. Why didn't it run away? I think it should be: this mantis must have left when it hatched. It was lonely and wandering around.

Being bullied by many people.

One day, he met a little boy, and probably thought it was funny, so he stepped on his wing.

Mantis couldn't dodge and was stepped on. The mantis quickly ran away reluctantly.

The next day, we caught it, so it couldn't escape.

I was lucky to see mantis today. That's great.

There are many small animals around us, such as singing slugs, cruel double-edged mantis, small snails with hard shells and powerful little ants. Among them, my favorite small animals are small ants. They live in groups all over the world. There are several kinds of ants in a nest, including males and ants.

Both male and female ants go out to hunt, and worker ants are responsible for building houses. After the queen and the queen mate, the queen's task is completed, but the queen has not completed the task, and every time the queen discharges thousands of eggs.

Every ant is a prophet. They can predict whether it will rain that day. If it didn't rain that day, they wouldn't move. If it rains that day, they will settle down in another safer place in droves.

Although male and female ants are not as big as caterpillars, they have a 100% chance to catch this monster. As for the specific predation process, I won't say it. Simply put, a few ants hold down the caterpillar's head, and a few ants bite the caterpillar's waist. The remaining ants continued to bite the caterpillar until they killed it. At this time, the ants carried the monster back to the nest, enjoyed it, and went to Xinhua Bookstore to find information about the ants.

The composition about mantis 1 Mantis is a beneficial insect.

Pin two "broadswords" to your chest and walk around with measured steps.

It's annoying, even the gecko, an insect-eating animal, has to give three points.

I didn't like it before.

Mantis has a small triangular head, and its two tentacles keep swinging.

Two green eyes looked around, and when the surroundings calmed down, it raised its "broadsword" and licked it on its mouth.

Once, my father brought back three big mantises. We put them on the book and looked at them with curious eyes.

No one expected that a mantis would "wave" to us, crawling around and licking its tentacles from time to time, as if to amuse us. Since then, I have had some good feelings for mantis.

Mantis is very picky about hunting.

Once, mantis met a grasshopper. Instead of rushing to catch the grasshopper, it first touched the grasshopper's head with a big knife, and then went to the grasshopper to try again. Unexpectedly, the grasshopper jumped hard and seemed to feel the danger and struggled desperately.

Mantis immediately took back his "broadsword" and dared not take any more risks to catch it.

It seems that mantis is very cautious in hunting.

Mantis is not only good at preying, but also has strong self-defense ability, which can scare and disguise people.

One day, when my father was washing the car, I was playing by the grass and accidentally found a mantis, so I picked up a stick with great interest to tease it, but something unexpected happened. It is not afraid of the huge me, it swings rhythmically, as if demonstrating to me. As soon as I saw it, I didn't dare to tease again.

After a while, it disappeared without a trace while I was not paying attention.

I like mantis.

2. mantis, commonly known as "knife mantis", is an insect-eating insect; The front legs are very developed, like sickles, and look very imposing. The head is triangular and the tentacles are filiform.

When attacked and ambushed by the enemy, the slender tentacles will stand up smartly and make a gesture of being ready to meet the enemy at any time.

Locust lang likes to act alone to catch pests, mainly feeding on cicadas, so people call it "killing insects"

"Ear seed" is a frequent period of bee beetle activity, so people often regard the appearance of locust beetle as a harbinger of the arrival of "ear seed".

In foreign countries, wasps are covered with a mysterious color.

The ancient Greeks observed that bees and beetles stood upright and held their arms high, so they called them "prophets" and showed respect for them. Italian farmers regard "disease" as the result of locusts; Sardinians regard locusts as a godsend and protect them doubly.

These are just bizarre legends with no scientific basis, but we can also observe the interesting life of locusts.

In cool autumn, leaves are sparse, and grasshoppers live between leaves and grass.

When the air is fresh and night comes, grasshoppers like to fall from trees and look for prey everywhere.

Its movements are very careful: the sharp edges of its front legs tightly hook the cracks in the trunk, and its rear legs contract elastically and rhythmically, so that its body can make a long distance deftly in a very short time.

Bees only eat creatures.

Sometimes it hides in the low grass and "waits for the rabbit". Once a small insect enters its "forbidden zone", it immediately pounces on it at a speed of per meter 1/20 seconds, holds down its prey with its claws and slowly swallows it. The scene is very interesting.

Once, a big locust beetle found a yellow-brown viper maggot in the grass, and immediately jumped spasmodically and reached a place about 5 cm away from fried oysters. Its wings extend obliquely in two toilets, its body is slightly lifted by a pair of stout hind legs, and two giant teeth' broadswords' are shrunk around its neck.

After this posture, the locust lang remained motionless, leaving only a pair of small eyes staring straight at the fried oysters.

At this time, the bombing squad seemed to realize the great danger, but it was too late. Just as it tried to spread its wings and take off, the locust lang's double knives had fallen violently ... the sun was setting and the grass looked black. This is the moment when the victorious locust lang triumphed.

Its action of climbing a tree is better than that of getting down, and its strength, lightness and beauty are straightforward.

Locust lang has developed vision, which is helpful for foraging and preying on prey; It also has unparalleled forelimbs of other insects, which is an indispensable organ for it to prey on the enemy.

Beelang has a strong hunger tolerance. It can live for months without eating or drinking, and always keep full of energy.

It is this ability that makes it dare to challenge strong enemies and use compromise and flexible methods to win by surprise.

Frogs are also good at destroying enemies in magical ways.

There is a grasshopper called Bian, which is the best in its family. There are colored films on its chest and forelimbs, so it is often hidden in the petals of the same color, which makes bees eat it in a hurry.

In addition, there is a long, slender and colorful locust, which grows in the desert.

It just hunts for a long time, just like a fisherman fishing, where there is a will, there is a way.

Locust lang also has an unusual ability, that is, its body color can change with the surrounding environment.

Due to the reflex of predation and swallowing, the mating of snake beetles often leads to tragedy: female locusts fall on the backs of male locusts and eat their heads mercilessly, which is a bad habit inherited from paleontology. After mating, they died one after another, and the young locust beetles after birth waved "double knives" all day to start their parents' lives again.

(Junior high school composition) There is an ancient saying in China that "the cicada is caught in the building, and the yellowbird is behind", which means that when the locust catches the cicada, it unexpectedly becomes a delicious meal for the yellowbird. Now people use this sentence as an idiom to describe a blind person who only cares about immediate interests and ignores the huge troubles behind him.

The composition describing insects, such as watermelon worms, ants and mantis, needs 300 words ... I divide the cake into small pieces and put it in front of the little ants.

I saw a little ant walking around the cake and never looked back.

Gee, doesn't it like eating? I'm going to see other little ants again. It has a good time here! I saw that they could lift the cake with their front feet and hurried to the hole, as if afraid that others would grab food from them.

Just then, the little ant who left without looking back came back, only to see the huge team behind him. Their heads gently collided, telling each other which direction to go and where there was something delicious waiting for them, which dazzled me.

Oh, so it went to find reinforcements! Ants can't move all the food at once.

Faced with such a big cake, I watched how they moved home.

Smart ants have their own ways.

Look, the old ant bit off a small piece and put it on the side, and then the little ant moved it away. When they moved home, they hurried back to help their companions. They took away the delicious food by breaking it into pieces.

Huh? Can that big cake walk by itself? It turns out that there are a few small ants under the cake. Jixin is working together to carry the cake in Qi Xin, moving it into the hole bit by bit. I really feel the power of small ants! I put the last two cakes on the ground, and the little ant who found the cakes immediately reported it again. Hehe, there are some greedy people lying on it stealing food! When I left, I seemed to hear the cheers of harvest coming from the ant hole. I was so happy!

The composition of forest concert is about 300 words. As night falls, a cool breeze blows away a little heat, and people who have been busy all day have already gone home to rest.

Doubt? Is the forest so busy? It turned out that the annual forest concert began.

Come and have a look with me! Ah, look! What a beautiful concert venue.

A bright moon hangs in the sky, and countless stars blink naughty eyes.

Fireflies flew around the venue with lanterns, making the concert dazzling.

The lotus in the river is in bloom, as if going to a concert.

The little animals sitting on it are all smiling.

The concert has started! The host, Brother Xiaoya, appeared in a formal suit. He said to the audience in a soft voice, "I, Fu Bu, officially started this concert.

"Applause rang out from the audience.

On the lotus leaf, several little frogs began to sing in unison.

"Quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack, quack quack quack quack quack, quack quack quack quack quack quack quack quack, quack quack quack quack quack quack quack quack quack, quack quack quack quack quack quack quack quack quack quack, quack quack quack quack quack quack quack quack quack quack quack quack, quack quack quack

After the beautiful melody ended, a gust of wind blew and the tree gave a "rustling" applause.

The duckling appeared again, bowing to the audience and saying, "After enjoying the singing of the little frog, please ask Miss Butterfly to dance for us.

This article; The contents were picked from the flowers in China ... Miss Butterfly flapped her wings, shook her body, twisted and twisted, and flew around, showing her graceful dance.

Guoguo and mantis play the violin and play elegant and beautiful music.

With the applause of "Pa Pa ……", the butterfly withdrew from the stage.

The program of the concert included goat tightrope walking, peacock dancing and monkey handstand ... The program became more and more exciting, and the animals reluctantly left until the end of the late-night concert.

Observing the Insect 300-word Composition The warm sunshine in the insect world shone on me, and I saw a group of "doctors" helping "patients" to treat diseases. They are "ladybugs"-then I walked on, and the "assassin" with a sharp knife lurked in the grass, as if waiting for the prey to appear.

Suddenly, a lizard appeared in front of it, and the "assassin" immediately attacked and quickly appeared in front of the lizard, waving its double knives and saying, "Click!" Lizards were beaten to death by assassins.

Then it became its wonderful dinner.

What kind of person is so powerful? In fact, it is the famous king of carnivorous insects-mantis.

Hey, hey ... Are you scared? I saw a general laying a trap. No matter how hot the weather is, it is still slowly weaving its own "encirclement".

Seeing such a scene, I can't help but admire their courage.

The evening arrived unconsciously, and I was walking on my way home. The insect world in my mind was so magical.

One day, I was reading in the shade of a tree, and an ant walked by my book. All my eyes are on it. I looked at it with strange eyes and couldn't help saying, "How are you?" It seems to ignore my greetings and go straight ahead. I put down my book and chased it.

I feel smaller. The two of us walked into a quiet forest, full of leaves, branches and wild shrubs.

It never seems to be afraid of everything here, and it moves forward proudly.

It looked around as if it were thinking.

On the way, it met many companions. They greeted each other and followed the ants happily.

They lined up neatly and kept moving forward.

My eyes glanced at the grass. In the distance, I saw a group of ants as if waiting for the arrival of an ant team. The team walked out of the forest and met their companions. The insects seem to be having a meeting. A big ant is standing on the highest rock, and its tentacles keep moving. In the distance, another team came. They wore beautiful and bright clothes and danced for these participants.

The insect dancer danced with rapt attention. I think their dance is better than all the dances in the world. Only insects can jump out.

I also saw ants working, ants looking for food, ants playing outside ... I also saw many, many ... I spent this afternoon with ants. I really want to become a little ant, go to their little world and play with them.

They quickly wiped out some "viruses" of the "patients" one by one until they were wiped out.

Ah! Ladybug.

Wherever you go, you make trees greener and flowers brighter.

Some students in our class, like me, love small animals and often catch small animals to raise, but they are distressed because of lack of space.

At this time, we knew that the other party had the same preferences as ourselves, so we got together and opened a small shop selling bugs.

Use spare time to catch bugs every day and form a "bug squad".

There are five people in the team, and everyone's share in the store is 20%.

At first, I found that some people in our class liked watermelon worms, so I fell in love with them and wrote an advertisement of "watermelon worms 1 yuan 10".

Because of the price advantage, it attracted customers just after opening.

My deskmate couldn't wait to buy 10 and said, "Great, there are only five 1 s at the school gate, which saves half the money!" I am also very happy, not because I made money, but because I am happy for these small watermelon worms that I rescued from mantis's mouth, because I helped them find a new home.

At noon, it is time for us to receive the goods. We came to the water hyacinth pool in Chunhui Park, pulled up the water hyacinths one by one, searched for loach fish with high nutritional value at the roots, occasionally found eel, and prepared to sell it at a low price, but still wanted to keep some for breeding.

We split it up.
