Camouflage tactics of insects

The reason why a wide variety of insects can survive in nature for a long time is not only because of their amazing fecundity and abundant food , also because they have a set of disguise skills.

Some insects have clever invisibility skills, such as grasshoppers, whose body color can often change with changes in their habitat. When it lives in green grassland, it wears green clothes; if it migrates to dry grass, it wears yellow clothes. There is also a kind of soil locust, which is earth-colored. They often live in the fields and it is difficult to find traces. Vampires on the human body - lice, appear black when they live in human hair; when they live on the human body, they gradually turn into skin color, so they are difficult to detect. This invisibility is due to the protective coloration of insects.

Some insects also use color to scare off predators. Like the spotted gadfly, its body color resembles that of a stinging bee. When natural enemies encounter them, they think bees are coming and dare not act rashly. The wings of some goldenrods and ladybugs have particularly conspicuous markings and gloss, which scare birds and other insectivores away from them. This is another protective color of insects - warning color.

Some insects are good at imitating other biological forms to confuse their enemies. Like a stick insect resting on a bamboo branch, it looks almost exactly like a bamboo branch.

The wings of the dead leaf butterfly are very beautiful from the front. When they are at rest, the wings are folded and erect and appear grey-brown. It is almost indistinguishable from the dead leaves. The wings of the tropical leaf locust are very similar to green leaves, and they look just like a leaf. These are another type of camouflage for insects.

Some insects adopt a temporary disguise when encountering natural enemies - pretending to be dead. On summer nights, people can often see scarab beetles hitting the wall and falling to the ground, pretending to be dead, and then resume activities when there is no movement around. The inchworm can imitate a dead branch and remain stiff and motionless. If someone touches it, it will fall to the ground and pretend to be dead.

The more clever the insect's disguise, the sharper the bird's eye response. This is the competition for survival. It is precisely because of this competition for survival that the creatures in the world can continue to evolve and develop. 6. The 600-word explanatory essay should be written in a logical order

Golden Autumn

Time keeps flowing forward, the weather gradually cools down, and the noisy cicadas are blown by the autumn sound. It disappeared and was replaced by the mournful chirping of crickets in the cracks of the stone slabs under the steps at night. ah! That lovely autumn is finally here.

Autumn is more prosperous than spring. Spring with brilliant flowers and trees is beautiful, but the fruitful autumn colors reveal the joy of harvest; autumn is more colorful than summer, with dense branches and leaves. Although summer is charming, the autumn colors on the trees full of golden leaves are more refreshing and pleasant; autumn is more vibrant than winter.

It was such a special autumn leaf! It has not completely faded away from its green color yet, and still exudes a strong fragrance. Autumn came to the orchard. Persimmon bent down and bowed so hard that the branches were about to break. Sister Lychee was so fat that her clothes burst, revealing her bulging, white belly. Huge apples hang all over the branches, showing sweet smiles, either shy or bold. When the autumn girl came to the farmland, the corn was very happy. It specially changed into a new golden dress and grinned, showing its golden teeth. In order to make itself more beautiful, the tomatoes put lipstick on their faces. Potato's excitement may have been too high, and his green mouth broke into laughter, revealing his yellow tongue. Autumn has come to the garden, and it has become a paradise for chrysanthemums. They may like this heavy golden color, so they choose to bloom their beauty in autumn. There are so many colors of chrysanthemums: yellow, pink, and white. . The big flowers and curly petals look like a little girl with curly hair.

Autumn brings a golden color to the earth and cotton-like clouds to the blue sky. The autumn wind is as cool as water, dyeing the world yellow with a hint of chill.

Our Campus

Recently, the High School Affiliated to Renmin University has just been listed as a key model school in Beijing and ranked first. This is not only because the learning atmosphere here is good and the teachers are excellent, but also because the hardware facilities here are first-class and unmatched by other schools.

As soon as you enter the gate, you will see special basketball courts, volleyball courts, tennis courts and badminton courts on the left and right. Each court is fully equipped and paved with turf or plastic, which is very suitable for students. Do the appropriate exercise. Going further is the distinctive local central garden of the High School Affiliated to the National People's Congress. The central garden consists of a circular lawn and several ancillary lawns surrounding it. Except for the circular lawn, which is only planted with flowers and grass, the rest of the lawn is planted with various trees and shrubs, and this tree hangs on every tree. The introduction of its name and characteristics enables students not only to relax in the green, but also to learn knowledge in the green.

After passing the "bath" of the automatic sprinkler in the central garden, walk north and you will see the school library. Although the library is only three stories high, about twenty meters long and two meters wide, it has many facilities. It not only includes the school’s library, 200-person online reading room, lecture theater, music classroom and classroom reference room, but also has a laboratory that the Renmin University Affiliated Middle School is proud of: the Student Network Laboratory of the Renmin University Affiliated Middle School. This laboratory is almost half the size of an ordinary classroom, but the computer equipment inside is very advanced. Computer experts from the school use their spare time to come here to delve into knowledge in various fields of computers, do various network experiments, and also produce He has produced many excellent works and trained many outstanding talents. Speaking of its history, it is even more proud. The network laboratory is not only the first network laboratory in China, but also the first laboratory completely founded and managed by students. The laboratory covers everything from the overall concept, material selection and color matching of interior design, machine assembly and debugging, and management. The structure and operating model are completely controlled by students, making it a large classroom that truly improves abilities in all aspects. Although I came a year late and did not catch up with its creation, I can feel the enthusiasm of its founders (current high school sophomores and seniors).

After leaving the library and walking west, you will find the complex building. The name is the Comprehensive Building. In fact, three of its four floors are canteens. It left the deepest impression on the students. Sometimes, we think the canteen is even more important than the teaching building. In the morning, noon, and evening, students will gather here to eat and chat together. After school in the afternoon, students come back here to do homework, play or discuss things together. When students organize their own activities, they will definitely say to gather in the cafeteria instead of the teaching building. The clean environment of the cafeteria set off the smiling faces of the students, leaving a deep mark on everyone's heart. ! !
