What are the main contents of insects?

The main contents are as follows:

1, black-bellied tarantula: Black-bellied tarantula has black villi on its abdomen, and these villi have black stripes. There are circles of black and white stripes on their legs.

The tarantula is a poisonous spider as terrible as a wolf and a member of the giant spider family. Tarantulas don't hunt in nets, but dig a cave underground to live. Except for tarantulas, ground spiders and raccoon spiders don't weave webs to hunt.

2, crab spider: it walks sideways, a bit like a crab, so it is called a crab spider. This spider doesn't use a web to hunt. Its hunting method is: ambush behind the flowers and wait for the prey to pass by, then go up and gently stab it in the neck to kill its prey.

Who knows the main content of entomology in Fabres ~

Henri fabre (1823— 19 15) is a famous French scientist and popular science writer. Born in a peasant family, he lived in extreme poverty since childhood, worked as a middle school teacher, and taught himself after 12 years. He has successively obtained bachelor's degree, double bachelor's degree and doctor's degree, and worked hard in middle school for more than 20 years. At the same time, he observed and studied insects and plants in his spare time and published excellent papers, which were affirmed by Darwin and rewarded by the Imperial Ministry of Education. However, his dream of "boarding the university platform" has never been realized, and his desire to open an independent entomology laboratory has never been realized. He was penniless in the first half of his life and barely had enough food and clothing in the second half, but Fabres did not give in to prejudice and poverty. He is still diligent in self-study, constantly expanding his knowledge reserve, carefully setting the research direction, persistently observing experiments, constantly achieving new results, and countering "prejudice" again and again. He taught students new knowledge of natural science, but also offended many biological colleagues who explained instinct with physiological functions. He is not afraid of being accused of being inconsistent with the cell theory and evolution theory in "/kloc-three great discoveries of natural science in the 9th century", and almost forgets everything. Fabres's greatest interest in his life is to explore the true face of the life world and discover the scientific truth contained in nature. It is precisely because he loves the truth that when writing Insects, he always "accurately describes the observed facts, neither adding anything nor ignoring anything". Fabres devoted himself to revealing and grasping the great cause of "truth-truth". This became the highest ideal and lofty labor of his life, and he felt happy and comforted for it. In this spirit, he gathered all his qualities and talents and made his own unique contribution to mankind. Fables was the first scientist to study insects in the natural environment. He devoted his whole life to the insect world, observed and experimented with insects in the natural environment, and truly recorded the instinct and habits of insects, thus writing the great work of entomology, Insect Tale. Fabres's heart is full of love for life and praise for all things in nature. He observed the nature of insects with human nature, and the instinct, habit, labor, marriage, reproduction and death of insects were all permeated with humanistic care. Looking back at social life with the nature of insects, wise philosophical thinking comes to the fore. In his simple pen, a serious academic work, such as beautiful prose, can not only make people gain knowledge and ideas from it, but reading itself is a unique aesthetic process. Entomology is not only immersed in awe of life, but also contains some spirit. That spirit is seeking truth, that is, pursuing truth and exploring truth. This is Faber's spirit. Without this spirit, there would be no entomology, and the tree of human spirit would lack a fruit of wisdom. The Insect Story written by Fabres is famous all over the world. This masterpiece occupies a place in the history of French natural science and literature. This masterpiece expresses the wonderful and amazing spirituality of insects in struggle for existence. Fabres recorded his achievements and experiences in insect research all his life in the form of most essays, carefully observed the life of insects and the struggle of races for survival and reproduction, and guided the vast amount of evidence of natural science with humanistic spirit, making the insect world a literary form for human beings to acquire knowledge, interest, beauty and thoughts, and writing the topic of small insects into a masterpiece with multi-level significance and all-round value. Such a work is really unprecedented in the world. No entomologist has such brilliant literary expression ability, and no writer has such profound entomological attainments. The author of Entomology was praised as "the founder of animal psychology" by French and international academic circles at that time. In his later years, Fabres published the last volumes of Insect Tales, which won him many readers not only in France, but also in European countries and all over the world. Literature respectfully called him "Virgil of the insect world", and French academic and literary circles recommended Fabres as a candidate for Nobel Prize in Literature. Unfortunately, before the Nobel Committee made up its mind to award him this grand prize, the great poet who praised insects had died in his eyes. Entomology has been translated into many languages and published. He is known as the "Insect Poet", and a large number of his works have been translated and published in China. The Tale of Insects is a book written by Fabres. He spent his whole life observing the life of insects and their struggle for survival and reproduction, and then recorded his observations in detail and accurately. Insects has ten volumes, each volume contains several chapters, and each chapter describes the life of one or more insects in detail and profoundly: spiders, bees, mantis, scorpions, cicadas, beetles, crickets and so on. Writer's masterpiece: The Insect Story is a book by Fabres. He spent his whole life observing the life of insects and their struggle for survival and reproduction. Ten volumes of entomology, each containing several chapters, each chapter describes the life of one or more insects in detail and profoundly: spiders, bees, mantis, scorpions, cicadas, beetles, crickets and so on.

The main contents of each chapter of entomology

1, the fable of cicada and ant This fable tells that many animals are preparing for winter before it comes. Cicada, who has been lazy, not only didn't prepare for the winter, but also joked that ants and other animals were storing food for the winter, which was stupid. But when the cold winter really comes, other animals survive the winter safely, while the lazy cicada is buried by heavy snow when looking for food in snowy days. The sun came out, and the ant brothers began to prepare food for the winter. They came to the tree, collected the fallen fruits, put them neatly under the tree to dry, and then transported them home bit by bit. 3. Wait for grubs [that is, cicada larvae] to break out of their shells and leave the fibrous branches until the tentacles can swing freely. Legs are strong and can stretch freely, and the claws in front can also stretch. Then they wobbled and fell. They are very clever. When they were in the tree, they found the place where they fell. Finally, when they found a place, they started working immediately without delay. 4. When mantis preys on prey and moves within the preying range of mantis, mantis will react. First, turn your head in the direction of the prey and keep a close eye on it. After that, the front feet (claws) are tightened, the center of gravity moves backward, and the line of sight does not leave the prey. When the time comes, the mantis will catch its prey at an extremely fast speed, stab its claws into its body, hold it tightly and eat it. 5. The life of the grey locust begins with the fertilized egg. The larvae just hatched from eggs have no wings and can jump, which is called jumping insects. The flea is similar in shape and living habits to adults, but smaller in size and immature in reproductive organs, so it is also called nymph. If an insect grows up gradually, it will shed its original exoskeleton when it is restricted by the exoskeleton and can no longer grow up. This is called molting. 6. Early in the morning, when the cicada was resting in a tall tree, the green grasshopper attacked. The attacked cicada was suddenly startled, then the attacked cicada and the attacked cicada twisted into a ball and fell down. 7, languedoc Scorpion languedoc Scorpion, this arthropod habit is covered with mysterious colors. It has six sections at its tail end, and its surface is smooth and bubbly. It's a gourd that makes and stores poison. Scorpion looks like water, but in fact it is highly toxic. The end of the poison cavity is a curved needle, which is dark and sharp. There is a small hole in the needle tip, from which the venom flows into the stung body. Languedoc scorpions are also very interesting when mating. 8. In the metal cage of Vertigo mantis, the posture of Vertigo mantis larvae remains unchanged after stopping in one place. It hooks the net with the tips of four hind paws, with its back facing down and motionless, and hangs high on the top of the cage. The four hanging points bear the weight of the whole body. The handstand posture is very difficult, but the handstand posture of flies is very different. Although the fly also hangs on the ceiling, it always takes time to relax, fly casually, walk in a normal posture, stick its stomach to the ground and spread its limbs in the sun. 9. Striped Spider and Mercerized Spider Among the six kinds of circular spiders, only two usually rest in the center of the web, namely, striped spider and mercerized spider. Even in the scorching sun, they will never easily leave the net and rest in the shade for a while. As for other spiders, they don't appear during the day. Their own way is to combine work and rest. There is a hidden place not far from their net, which is made of leaves and thread. During the day, they hide in it, quietly, and let themselves be deeply lost in thought. 10, COLEOPTERA, their bodies are bulging like half peas, and their COLEOPTERA is smooth or fluffy. Usually, black COLEOPTERA insects have red or yellow stripes, or red or yellow COLEOPTERA insects have black stripes, but some ladybugs have yellow, red or brown COLEOPTERA insects without spots. These bright colors are used as warnings to scare away natural enemies. 1 1. Common cicadas like to lay eggs on dry branches. It chooses the smallest branches, most of which are as big as grass and pencils. These twigs rarely hang down, they are usually tilted and almost all of them are dead. Cicada found a suitable twig and stabbed it in the chest with a sharp tool, as if it were stabbed obliquely with a needle. A dead branch is often pierced into thirty or forty holes. Its eggs are laid in these small holes. Generally, each hole lays about ten eggs, a total of about three or four hundred. 12, cicada's egg When spring comes, as long as you have a pair of eyes, you can see everything in the world. People can find a strange little thing on dilapidated walls and dusty roads, or on those empty land. It's a small bundle of firewood. For some reason, it can move freely and jump forward. The inanimate things have become living things, and the immobile things can actually beat. What the hell is going on here? 13, sawdust bees We know that many bees, like sawdust bees, do not build their own nests, but only use nests left or abandoned by other animals as their shelters. Some bees will live in the former residence of Mei Sen bees, some will live in earthworms' tunnels or snails' empty shells, some will occupy branches once occupied by bees, and some will move into sandpits once occupied by bees. 14. If you walk in the garden, you will find some delicate holes in the leaves of lilacs or roses, some of which are round and some are oval, just like someone has cut them skillfully. They do this because these little leaves are very important in their lives. They put these small leaves together and put them in a needle-hoop-shaped bag, which can store honey and eggs. Every wasp's nest has a bag in the shape of an injection ring, and those bags overlap one after another. 15, Spain's homemade rhinoceros head I hope you still remember that sacred beetle, which consumed its time and made it into a ball, which can be used as food or as the foundation of a pear-shaped nest. After observing the work of this beetle for a long time, I began to wonder if I strongly praised its instinct. Maybe my estimate is wrong. Do they really care about their larvae and prepare the softest and most suitable food for them? 16. Two kinds of exotic grasshoppers surround the high embankment of the rural sandy land of Kaben Trust, which is the favorite haunt of wasps and bees. Why do they like this place so much? The reason is mainly because the sunshine in this area is very abundant, and this area is also very easy to dig, which is very suitable for wasps and bees to live and work here. There are mainly two kinds of bees in this weather in May. One day in September, my youngest son Paul and I ran out to have a look at the hornet's nest. Little Paul pointed to a place not far away and shouted at me, "Look! A hornet's nest. Just over there, a hornet's nest, clearer than anything! " Sure enough, about twenty yards away, little Paul saw something moving very fast, jumping up from the ground one by one and flying away quickly, as if those small craters were hidden in the grass and about to erupt one by one. 18, the adventure sea of grubs is the place where creatures first appeared, and there are many kinds of grotesque animals, which makes it impossible to count their specific numbers and distinguish their specific species. The original models of these animal kingdoms are preserved in the depths of the ocean. This is what we often say, the ocean is an invaluable treasure house of human beings and one of the important conditions for human survival. 19, Sissis I hope you've heard of the strange thing about sweeping beetles to make balls, and you're never tired of it. I have told you about scarab and Spanish rhinoceros, and now I want to talk about other kinds of this animal. Good fathers are rare except in higher animals. In this respect, birds are excellent, and humans are best qualified for this responsibility. Among lower animals, fathers are indifferent to family affairs. Few insects are exceptions. 20. The petite red striped bee's nest is built in loose and easily drillable soil. On both sides of the path, on the sunny mud beach, the grass grows sparsely, which is an ideal habitat for wasps. In spring and early April, we can always find them in such places. 2 1, crickets living in the grass are almost as famous as cicadas. They perform quite well in several model insects. The reason why it is so famous is mainly because of its location and its excellent singing talent. 22. Fly Bees You already know how red striped bees and wasps paralyze caterpillars or crickets to feed their children, and then how to close the hole and leave the nest to fly elsewhere. But not every kind of bee lives like this. Now you will hear another kind of bee, which feeds its children with fresh food every day. This is a fly trap. 23. The parasite will go to the bare place scorched by the sun in August and September. Let's find a sunny slope, where it is often hot because the sun has scorched it. It is precisely this place where the temperature is like a stove that is the goal of our observation. Because it is in this place that we can gain a lot. This hot land is often a paradise for wasps and bees. 24. Metabolic workers have many insects, and they are doing extremely valuable work in this world, although they have never received corresponding remuneration and titles commensurate with them. When you approach a dead mole and see ants, beetles and flies gathering on it, you may get goose bumps and run away. You must think they are all terrible, dirty insects and disgusting. That was not the case. They are busy cleaning up the world. Let's look at some of these flies, and we can know how beneficial their behavior is to human beings and the whole nature. 25. Dendrolimus punctatus has several pine trees in my garden. Every year, caterpillars come to nest on this pine tree, and the pine leaves are almost eaten up by them. In order to protect our pine trees, I destroy their nests with long forks every winter, which makes me exhausted. You greedy little caterpillar, it's not that I'm rude, it's that you are too presumptuous. If I don't get rid of you, you will steal the show. No more pines full of needles can be heard whispering in the wind. 26. Cabbage caterpillar Cabbage can be said to be the oldest of all our vegetables. We know that people in ancient times began to eat it. In fact, it has existed on the earth for a long time before humans began to eat it, so we really can't know when it appeared, when humans first planted them, and what methods were used. Botanists tell us that it was originally a wild plant with long stems and small leaves that grew on coastal cliffs. History is unwilling to spend more ink on the record of such a trivial matter. 27. Peacock moth Peacock moth is a beautiful moth. The largest one is from Europe, covered with reddish-brown fluff, with a white bow tie around its neck and gray and brown dots on its wings. There is a faint zigzag line in the middle, the wings are surrounded by gray edges, and in the middle is a big eye with shiny black pupils, which is inlaid with many colors, including black, white, chestnut and purple arcs. This moth is made from a very beautiful caterpillar. Their bodies are yellow with blue beads embedded in them. They live by eating apricot leaves. 28. Beetles looking for Fusarium Let's talk about beetles looking for mushrooms. This is a beautiful beetle, small and black, with a white velvet belly and a round shape, like a cherry pit. When it rubs its belly with the edge of its wings, it will make a soft "chirp" sound, just like the sound made by a bird when it sees its mother coming back with food. The male beetle also has a beautiful horn on its head. 29. Children who love insects Nowadays, many people always like to attribute all people's personalities, talents and hobbies to heredity. In other words, it is acknowledged that the wisdom of human beings and all animals comes from ancestors. I don't entirely agree with this view. I now use my own story to prove that my hobby of loving insects was not inherited from any ancestors. My grandfather and grandmother have never had the slightest interest and affection for insects. I don't know my grandfather very well. All I know is that he went through a rather difficult time. No matter who the striped spider is, he probably won't like winter. Many insects hibernate in this season. But that doesn't mean you have nothing to observe. At this time, if an observer searches in the sand where the sun can shine, or removes underground stones, or searches in the Woods, he can always find something very interesting. This is a real work of art, and those who are lucky enough to enjoy this work of art are really happy. At the end of the year, the joy of finding this kind of art made me forget all the unhappiness and the climate getting worse every day. If someone is searching among weeds or willows, I wish him to find something mysterious: this is the nest of striped spiders. Just like it appeared in front of my eyes. 3 1, the tarantula spider has a bad reputation: most people think it is a terrible animal, and they want to trample it to death as soon as they see it, which may be related to its ferocious appearance. However, a careful observer will know that he is a very diligent worker, a talented weaver and a cunning hunter, and he is also interesting in other ways. Therefore, even if it is not from a scientific point of view, spiders are an animal worthy of study. But everyone says it is poisonous, which is its greatest sin and the reason why everyone is afraid of it. Yes, it does have two fangs, which can kill its prey at once. 32. Crucho Spider Crucho Spider is an extremely clever loom. As far as spiders are concerned, Crucho Spider is very beautiful. Its name comes from one of the three ancient Greek goddesses of fate, and it is also the youngest one. She is in charge of the spinning spindle, from which everything has its own different destiny. Crucho spiders can spin the most exquisite silk for themselves, but the goddess Crucho can't spin a happy fate and a comfortable life for us. What a pity in the world! Spiders that can weave webs can be called textile experts. They use cobwebs to catch bugs trapped by themselves. It can be said that it is "something for nothing". There are many other kinds of spiders. They use many other clever ways to find food, and they can also wait and get a bumper harvest. Several of them are very accomplished in this field, and almost all books about insects will be listed. It is a black spider, and some people call it the American tarantula. They live in caves, just like the European tarantula I mentioned before. But their caves are more complete and detailed than those of the European tarantula. 34. Spider Web Architecture Even in the smallest garden, you can see the traces of spiders. They are all gifted weavers. If we take a walk at dusk, we can look for clues from a cluster of rosemary. The spiders we observe tend to crawl very slowly, so we should just sit in the bushes and observe. There is plenty of light there. Let's give ourselves another title, called "Spider Web Observer"! Few people in the world are engaged in this profession, and we don't have to expect to make some money from this industry. 35. The geometry of spiders When we observe the webs of spiders, especially silkworms and striped spiders, we will find that their webs are not chaotic. Those spokes are evenly arranged, and the angles formed by each pair of adjacent spokes are equal; Although different spiders have different spokes, this rule can be applied to all kinds of spiders. We already know that spiders weave webs in a special way. They divided the web into several equal parts, and the same spider had the same number of parts. 37. Among the six kinds of circular spiders, only two usually rest in the center of the web, that is, the striped spider and the mercerized spider. Even in the scorching sun, they will never easily leave the net and rest in the shade. As for other spiders, they don't appear during the day. They have their own ways to coordinate work and rest. Not far from their net, there is a hidden place made of leaves and thread. During the day, they hide in it, quietly, and let themselves be deeply lost in thought. Although this sunny day makes spiders dizzy, it is also the most active time for other insects: locusts jump more lively and dragonflies fly more happily. 37. Crab Spider Although the striped spider we mentioned earlier works very hard, it has been tirelessly building a comfortable nest for its eggs. But in the end, it can no longer take care of its home. Why? Because its life is too short. When the first cold current comes, it will die. Its eggs will not hatch until winter. It had to leave its nest. If the baby can be born when the mother is still alive, I believe that the spider mother will take care of the little spider like a bird. Another kind of spider proved my guess; It is a spider that can't weave a web: it just waits for its prey to run close to it, and it walks sideways, a bit like a crab, so it is called a crab spider.

Seek the full text of Fabres, a colorful web spider in Insect Tale (60 points).

After drinking a mouthful of tea, I started reading a book with a little excitement-Insects, which is a masterpiece handed down from ancient times by Fabres, an outstanding French entomologist and writer, and also an immortal work. It combines the author's lifelong research achievements and life feelings in one furnace. Fabres studied the insect world all his life. I really admire his persistence and perseverance. This book is full of surprises and interests. Through this book, I learned the real face of the insect world, and I discovered all kinds of scientific truths contained in nature. This is really an extremely valuable life movement. Between the lines is full of the author's own respect and love for life. How wonderful the insect world is. The author described the scene in the insect world to us with his vivid writing and relaxed and humorous style. Because this encyclopedia of science is also literary, every word in it reflects the author's feelings and the unique personality of insects. Poplar beetle is like a miser, wearing a short dovetail dress that seems to lack cloth; Little beetle selfless dedication for future generations, heartbreaking for children; And the little sparrow bitten by a poisonous spider will also eat happily. If we feed him slowly, he will even cry like a baby. Also, fireflies, ants, spiders, crickets, caterpillars, swallows, sparrows ... interesting stories and vivid insect scenes cover almost all the details about insects eating, protecting themselves, mating, raising offspring, working, hunting and life and death. As if I were on the spot, I was brought into the world of insects again and again. What a wonderful life! I also know why Lu Xun regarded it as a model of "talking about insect life". That's true! Among them, two kinds of insects, dung beetle and mantis, impressed me the most and overturned my previous views. Dung beetles is the dung beetles we hate very much. They deal with the dung and dung all day and knead them into balls for themselves to eat, but they are veritable "cleaners" of nature, especially like to clean up the dung left by unsanitary pets on the grass, so the lawn in the park becomes fresher and the flowers smell better. The beautiful mantis in green is a carnivorous insect, and likes to eat mosquitoes, locusts, moths and crickets. Its two arms are the most terrible swords. Although slender and elegant, as long as there are insects flying over, it immediately brandishes a broadsword and quickly kills. I often think: although dung beetles is ugly, it tries to clean the earth and make the home of mankind better; Mantis is beautiful in appearance, but very cruel in heart. We should see its cruel nature and not be confused by its beautiful appearance. Therefore, whether he is beautiful or ugly, there is a reason for his existence. Only when the creatures on the earth live in harmony can the ecological balance be maintained. Only through competitive selection can the evolution of species be obtained. Entomology is indeed a miracle. It is a life movement composed by Fabres, an outstanding representative of human beings, many ordinary people in nature, insects and a book that can never be read. At the critical moment when mankind is about to enter the new century and the earth is about to usher in the ecological era, such a miracle may provide us with more precious enlightenment. It is full of reverence for life, but also contains the spirit of seeking truth from facts, which gives me great inspiration: in life and study, we should learn from Fabres's courage and perseverance in exploring the world and pursuing truth, have a rigorous scientific attitude like Fabres's in doing everything, and insist on "accurately describing the observed facts without any modification or neglect". We must persevere in everything, even if the conditions are difficult, we must persist in fighting for our ideals!

What kinds of spiders are mainly described in entomology?

This paper mainly describes five kinds of spiders: tarantula, web spider, palace spider, striped spider and crab spider. 1, Tarantula: Tarantula has black fluff and brown stripes on its abdomen and circles with gray stripes on its legs. It likes to live on the dry beach with thyme. The tarantula waits patiently for the hunting opportunity until the opponent is facing it and the head is easily hit, then it rushes out immediately, otherwise it will never risk its life. 2. Rotary Spider: Rotary Spider is a talented architect. When it spins a web, each spider silk keeps a certain distance, just like measuring it with a ruler. Circular web spiders feed on moths, flies, butterflies, grasshoppers and scarabs that stick to the web. When spiders eat, they don't chew food with their teeth, but dissolve food into gravy with digestive juice in their mouths and suck it. 3. Labyrinth spider: It nests in the bushes far away from the net. There is a pile of dead wood, which is messy and looks a little dirty. Just under this simple cover, there is a silk sac made more carefully, which is the egg of a labyrinth spider. 4. Striped Spider: As far as habits and colors are concerned, striped spiders are the most perfect spiders I know. There are yellow, black and silver stripes on its chubby body as big as hazelnut kernel, so its name is "striped spider". Their eight feet surround their bodies, just like the spokes of a wheel. 5. Crab Spider: This spider can't hunt with a net. Its predation method is: ambush behind the flowers and wait for the prey to pass by, then go up and gently stab its neck to kill its prey.
