In addition to hunting, spider silk spinning has a great significance in his life, that is, the continuation of life.
There is one in Africa.
Tightly wrap an egg pack with sticky spider silk. The mother spider guards the egg pack all day long, waiting for the baby spider to be born. About a month later, the egg pack cracked a small opening, and the little spiders crawled out one by one.
These little spiders are born to eat. The mother spider lays more than a dozen food balls, enough for the baby spider to eat for three days. After three days, the baby spider has grown a lot and begins to shed its skin for the first time.
At this time, the mother spider uses her thread to gather the spiders together, and then lies on top of the spiders. Hungry little spiders were stirring.
crawled onto the body of the mother spider, and began to hesitate a little, but I don't know which little spider took a bite first, the mother's skin was bitten, and the other brothers and sisters smelled blood and bit like their mother. In a moment, the mother's body was crawled all over with her children, each of whom had a sharp one.
Hundreds. Pierce the mother's epidermis and stab into the mother's body. The mother remained motionless, allowing more than a hundred of her children to suck the fluids in her body, feeding them again and again.
The body of the mother spider is enough for the baby spider to eat for four days. After four days, the baby spider grew up and grew a little more, and the mother spider had already been eaten. Not only did the mother feed her children, but she also awakened their predatory instincts with her sap.
The mother spider willingly acts as the first prey for her children. The children learn to hunt in the process of eating their mothers, and only in this way can the baby spiders survive in the harsh environment.
The female spider is known to eat the male spider and is also known as the 'Black Widow'. But people don't know that female spiders eat male spiders not only to nourish themselves, but also to give birth to baby spiders. I think both the male and the female spider know this, they gave their lives for their children, and what a pain it is when the mother spider eats the male spider.
There is a great love between spiders and spiders that is rare in the animal kingdom.

This year, the cicadas are singing early. Before the azaleas were scattered, the intermittent sound of cicadas was heard. In recent months, the cicadas outside the window have become more aware of it, which makes people who are busy with things very annoyed to listen to it.
One day, I picked up a sick cicada under the tree, its transparent wings converged, and its body trembled slightly, but there was no sound. It's just a little thing that lives on the tree. It's so small, but the voice is so loud, it resounded all summer!
I once asked: Why bother? It was just one summer!
My friend said, "You know?" It waited 17 years for a summer.
Only this summer, it came out of the dirt and grew from the larvae. When the autumn wind blows, its life will be over.
Buried in the soil for 17 years, and lived for a summer when he came out, why?
My friend said: That's how life was supposed to be. It must live well for the sake of the continuation of the name of life. No matter how much it is 90 years or 90 days, you just have to live well. Oh! That's the meaning of cicada's life!
In the slanting sun, when I think of the color of the autumn wind, I forgive the annoying deafness!
Imitation: Life is really a miracle, a summer lotus that grows out of the sludge actually blooms a flower as pure as blood; A fine black firefly can shine like a star in the dark night, and a cicada has waited for 17 springs, summers, autumns and winters, and can show the meaning of life in just one season.

Grasshopper has a wide distribution area, has distribution in the north and south of China, mainly inhabits broad-leaved trees, the life cycle is 3 5 years, the adult life span is 2 3 months, the oviposition period is in the month of each year, the overwintering eggs hatch in May and June of the following year, and the egg period is nearly 300 days.
The activity of the overwintering nymphs was affected by ground temperature and the sap of the host plant, and when the temperature was higher than 10 15, the sap of the tree began to flow rapidly, and the overwintering nymphs began to sting, suck and feed. Nymphs (cicada ants) hatched from overwintering eggs, burrow into the soil and suck the sap at the roots of the host plant. As the age increases, they create earthen chambers of different sizes and shapes to live in.
Part of the wall of the earthen chamber is attached to the roots of the plant so that it can be fed. When the temperature drops in autumn, they burrow into deep soil for wintering, and then migrate upward to the roots of trees after the spring is warm.
The largest number of nymphs in the soil is in May, when the overwintering eggs hatch into the soil in large numbers, and the last instar nymphs are about to emerge and molt into adults. After completing the whole life process of the nymphs in the soil, the mature nymphs emerge from the soil in May and August, and crawl to the branches of shrubs, weeds, stems, etc., and fix themselves on the bark branches and leaves with their claws and the thorns of their forefeet, molting and feathering into adults.
Adults are at their peak in June and late in October. About 20 days after the adult emerges, the tail lays eggs, the adult oviposition period is the peak period of adult oviposition in July and August, the end of oviposition is in October, and the final period of adult eggs is November. Adults mostly emerge at 20:22:00 at night and 4:6 at 6:00 in the morning, and the ratio of females to males is basically 1:
1 ratio.

Rainbow. After the rain, the air was fresh and I walked out of the house. Everything had just faded from the rain, and when I looked up at the sky, I saw a rainbow standing in the sky.
The appearance of red, orange, yellow, green, blue, purple, and rainbow makes the originally gray sky have traces of sunlight, as if all the wonderful colors in the world are blooming at this moment. It's so smooth, so gentle, and it doesn't feel vulgar, gently floating in the sky, it erases the haze and decorates the sky after the rain. I looked at the rainbow and watched it fade away.
The rainbow has been around for a short time, but it has left people with the best memories. The sky and rain make it so gorgeous, and when it disappears, it doesn't leave a trace.
Haven't we been around longer than rainbows? I think that's what life is all about. Cherish life, and give full play to infinite value in a limited life; Try your best to do everything well, so that life becomes colorful, just like a rainbow.
This is the rainbow, not in terms of length, but in perfection.
The sky is clear, and the beautiful rainbow is still in my mind.

The essay "Cicada" uses three explanatory techniques: listing numbers, making comparisons, and facsimile appearances.
1. Column figures: accurate, rigorous and specific.
In order to make the thing to be illustrated concrete, you can also use the method of column numbers so that the reader can understand. It should be noted that the numbers quoted a lot must be accurate, and inaccurate numbers must not be used, even the estimated numbers must have a reliable basis and strive to approximate them.
2. Glossary appearance: more vivid and concrete.
In order to make the object to be explained more vivid and concrete, the appearance can be copied and written vertically.
3. Comparison: distinct, prominent, and concrete.
Comparison is an explanatory method that compares two things or phenomena of the same or different categories to illustrate the characteristics of things. Explain some abstract or relatively unfamiliar things, and compare them with concrete or familiar things, so that readers can get a concrete and distinct impression through comparison. The characteristics of things also tend to be revealed in comparisons.
When making comparisons, it can be similar or different, and things can be "horizontally proportioned" or "vertically proportioned".
