Souvenir entomology, also known as insect world, insect story, entomological notes or insect story, is a French entomologist and writer Jean-Henri? Casimir? Fabres's long biological works, * * * ten volumes. This work is an insect biology book, which summarizes the species, characteristics, habits and mating habits of insects, records the real life of insects, expresses the spirituality of insects in struggle for existence, and also records Fabers' motivation, life ambition, knowledge background and living conditions of being obsessed with insect research. The author combines the colorful life of insects with his own life feelings, treats insects with a human attitude, and reveals his respect and love for life between the lines.

The main contents of each chapter of entomology are as follows:

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 doesn't plan to spend the winter, but also jokes about the stupidity of animals such as ants who are storing food for the winter. When the cold winter really came, all the other animals passed the winter safely, but the lazy cicada was buried in the snow when looking for food on snowy days because there was no food to eat.

2, cicadas and ants

After an autumn rain between ants and cicadas, green leaves and grass were covered with golden coats. 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 carried them home bit by bit.

3. The cicada is out of the hole

After grubs break out of their shells and leave the fibrous branches, 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. Mantis preys

When the prey moves within the range of mantis, mantis will respond. 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. Grey locust

The life of locusts begins with fertilized eggs. 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. Green grasshopper

The grasshopper attacked early in the morning, while the cicada was resting high in the tree. The attacked cicada was suddenly startled, then the attacker and the attacked cicada twisted into a ball and fell down.

7. languedoc Scorpion

Languedoc Scorpion, the habit of this arthropod, is covered with a mysterious coat. 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. Spinal mantis

In a metal cage, mantis larvae remain 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.

A summary of each chapter of entomology

9. Striped Spider and Mercerized Spider

Of the six kinds of spiders, only two usually rest in the center of the web, namely the striped spider and the 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, with smooth or fluffy sheath-like wings. Usually, black coleoptera has red or yellow stripes, or red or yellow coleoptera has black stripes, but some ladybugs have yellow, red or brown coleoptera without spots. These bright colors are used as warnings to scare away natural enemies.

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.

12, cicada slough

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?

13, wood 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 bunkers once occupied by bees.

14, cotton bees and fat 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.

15, homemade 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?

16, two rare 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.

17, wasp

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, larval adventure

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.

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.

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.

2 1, cricket

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. Flying 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, 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.

24. metabolic workers

There are many insects, and they are doing extremely valuable work in this world, although they have never been paid or given a proper title. 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

There are some 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. Pieris rapae

Cabbage is almost the oldest of all our vegetables, and we know that people have been eating it since ancient times.

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.
