What are the main contents of Chapter 3 of Insects?

The main content of the third chapter of "The Insect Book" describes the "modeling technique" of the scarab beetle. "Insects" is a long work of popular science literature written by the French entomologist and writer Fabre.

The work is a true record of the life of insects, and expresses the spirituality of insects as they struggle for survival.

1. The first chapter summarizes the interesting living habits and superb instincts of the scarab beetle that pushes the dung ball, the arthrophthralis mud wasp that preys on Gidding, and the yellow-winged locust mud bee. 2. Summary of the content of Chapter 2:

The living conditions of the burr sand mud wasp that operated on the larvae of the yellow tiger in the barren stone garden were recorded. 3. Chapter 3 summarizes: The parasitic behaviors and feeding patterns of stone wasps, bee flies, and fold-winged wasps are recorded.

4. Chapter 4 summarizes: It records the predatory and nesting characteristics of long-bellied wasps, leaf-cutting wasps, fat collecting bees, and longhorn bees under the instinct of long-bellied wasps, leaf-cutting wasps, lipid collecting bees, and longhorn bees.

The author mainly describes stone silkworms.

The larvae of the stone silkworm moth live in ponds and most of the time they prefer to hide very cleverly in small sheaths. When building a nest, the stone silkworm uses its teeth to tear the rotten root bark into filaments of suitable thickness, and then weaves them together in a regular manner, so that their bodies can hide in it.

Sometimes, the stone silkworm will also use very small shells, stones, sand grains, etc., to make a small sheath in a patchwork, which is the most creative shape. The sheath is not only a warm home, but also a configuration to defend against aggression and fulfill the dream of freedom.

A water beetle lurking next to the stone found the stone silkworm and immediately swam over and quickly grabbed the small sheath of the stone silkworm. The stone silkworm inside obviously sensed the attack, and used the golden cicada's clever plan to break out of its shell, slipped out of the small sheath in a hurry, and escaped without a trace in the blink of an eye. The savage water beetle continued to be ruthless, desperately tearing at the small sheath, until it found out that it had been deceived by the stone silkworm, and then it was frustrated and frustrated to drop the empty sheath and go elsewhere to forage for food.

Stone silkworms rely on instinct to create a small "home" that can defend against aggression.

Chapter Analysis: The author of this book is the scientist Fabre.

There are many wonderful insects in the book, many of which I don't recognize. I'm going to tell you about "The Clever Stone Silkworm".

Stone silkworms are the larvae of stone silkworm moths, and they live in water. It is hidden in a small sheath made of dead branches, like a delicate woven work of art. The sheath is the movable house it carries with it, and it is also its protective shell.

When other aquatic animals want to attack it, the stone silkworm will come up with a clever plan to "get rid of the shell of the golden cicada", and it will slip away in the blink of an eye!

The stone silkworm will also change the size of the air volume in the small sheath, allowing itself to float to the water surface to bask in the sun for a while, sink to the bottom of the water to rest, and float in the water for a while. Like a human submarine.

Don't look at the stone silkworm is very small, but its ability is very strong. I want to be like a stone silkworm, not afraid of my young age, study hard, and make progress every day.

also has a good ability.

What a wonderful harmony of nature! I wanted to be a biologist and study a lot of insects when I grew up. Make insects and humans good friends!

"Insects".The first three chapters are summarized as follows:

1. The fable of the cicada and the ant.

This fable tells the story of many animals preparing for the winter before winter approaches, and the cicadas, who have been lazy, not only do not prepare themselves for the winter, but also laugh at the stupidity of the ants and other animals that are stocking up for the winter. When the cold winter really came, the other animals survived the winter, but the lazy cicada was drowned in the snow because it had no food to eat, and was buried in the snow while searching for food.

2. Cicadas and ants.

After an autumn rain between ants and cicadas, the green leaves and grass have changed into golden clothes. When the sun came out, the ant brothers began to prepare food for the winter, they came to the tree, collected the fruit that fell from the tree, placed it neatly under the tree to dry, and then carried it home little by little.

3. The cicada comes out of the burrow.

Grubs. That is, the larvae of the cicada break through the shell and leave the fibrous branches, and wait until the tentacles can swing freely. The legs are more strong and can be stretched freely, and the front claws can also be retracted.

Then they staggered and fell, and they were clever enough to find the place where they fell while they were in the trees, and at last they found the spot, and they began to work without delay.
