What does the first chapter of entomology mainly introduce?

The first chapter is about the tradition of ancestors.

Everyone has his own unique personality. Sometimes, this character seems to be inherited from ancestors, but when you want to ask where this character comes from, it is very difficult.

Because my ancestors were uneducated country people, the only thing they knew and cared about was their own cattle and sheep. Only one of my grandparents has read this book.

Chapter II Mysterious Pond

I never get bored when I stare at the pond. In this small green world, I don't know how many busy little lives will be busy all the time.

By the pond, piles of little black tadpoles can be seen chasing and playing everywhere; The red-bellied salamander also swings its wide tail like a rudder and moves slowly forward; In the reeds, we can also find groups of silkworm larvae, who hide their bodies in small sheaths made of dead branches-this small sheath is used to defend against natural enemies and all kinds of sudden disasters.

Chapter III Silkworm

I put some small aquatic animals in the pond. They are called stone silkworms. To be exact, they are the larvae of the stone silkworm moth, cleverly hidden in a small sheath made of dead branches.

In fact, this kind of trailer can be regarded as a very delicate woven work of art, which is made by soaking the roots and skins of plants in water and falling off.

Chapter IV dung beetles

Six or seven thousand years ago, people first talked about dung beetles. Farmers in ancient Egypt, when irrigating their farmland in spring, often see a fat black insect passing by them, busy pushing a ball back. Of course, they were surprised to notice this grotesque rotating object, just like the farmers in Brovin today.

The fifth chapter Mei Sen bees

There are many kinds of insects that like to nest near our home. Among these insects, the first one that aroused people's interest was an animal called the recumbent bee.

The family knows nothing about this little neighbor. Why? Mainly because of its natural, quiet and peaceful nature. Indeed, this little thing lives in a hidden way and it is difficult to attract people's attention.

Chapter VI Cicada

The worst criminals are ants. I have seen them bite the tip of a cicada's leg, drag its wings and climb on its back. Even once, a fierce and strong disciple grabbed the cicada straw in front of me and tried to tear it off.

In the end, there were more and more troubles, but the singer had to put aside his well and escape quietly. So the ants achieved their goal and occupied the well. But the well soon dried up and the pulp was eaten up at once.

Chapter 7 bees, cats and red ants

I hope to know more about bees. I have heard that bees have the ability to tell the direction, and no matter where they are abandoned, they can always return to their original places by themselves. So I want to try it myself.

In this process, my hand was inevitably stabbed several times, but I persisted, and sometimes I forgot my pain. I just held the bee tightly and finished my work. As a result, over 20 bees were damaged. When I opened the paper bag, the bees that had been bored for a long time flew in all directions, as if trying to tell which direction to go home.

Chapter VIII Mantis

There is an insect in the south that, like cicadas, can arouse people's interest, but it is not very famous because it can't sing. If it also has cymbals, its fame should be much greater than that of famous musicians, because its shape and habits are very unusual. This will be an excellent musician.

Chapter 9 Mine Bee Driving Tunnel

My bee is a slender bee. They are different in size. The big one is bigger than the wasp, and the small one is smaller than the fly. But they have a common feature, that is, there is an obvious ditch at the bottom of the abdomen, and a thorn is hidden in the ditch. When the enemy invades, the thorn can move back and forth along the ditch to protect itself.

Chapter 10 Fireflies

Among all kinds of insects, few can shine. But one of them is famous for its light. This strange little animal seems to have a lamp on its tail to express its good wishes for a happy life.

Even though we have never seen it, we have never seen it fly across the grass in the dark, and we have never seen it fall from the full moon.

Chapter 1 1 Managed Worm

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.

Chapter 12 Cicada's Egg

When spring comes, as long as you have a pair of eyes, you can see everything in the world clearly. 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?

Chapter 13 Firewood sawfly

We know that many bees, like sawflies, 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.

Chapter XIV Cotton-picking Bees and Fat-picking Bees

If you walk in the garden, you will find some delicate holes in the leaves of lilacs or roses, both round and 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.

Chapter 15 Self-control of Spanish rhinoceros head

I hope you still remember the sacred beetle, which consumed its time. Make 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?

Chapter 16 Two Strange Grasshoppers

The area around the sandy high embankment in Kaben Trust 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.

Chapter 17 Wasps

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.

Chapter 18 The adventures of grubs

The ocean is the place where creatures first appeared, and now there are many strange-looking animals, which makes it impossible for people 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.

Chapter 19 Xixi

I hope you're not tired of hearing about sweeping beetles and making balls. 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.

Chapter 20 Petite red striped bee

The nest of the red striped bee is built in loose soil and can be easily drilled through. 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.

Chapter 21 Crickets

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.

Chapter 22 Catch flies and 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.

Chapter 23 Parasites

I'm going to the bare canyon in August and September and I'm scorched by the sun. Let's find a slope facing the sun. This slope is often very 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.
