One summer night, my father took me to catch crickets. Unexpectedly, besides crickets, we also caught a firefly larva. It is orange all over, with three feet and a big belly. It looks like a little silkworm. There is a big scale on its head, which just covers the whole head. Its eyes are as big as sesame seeds, and there is only one light-emitting device at its tail. We conclude that it is a female insect because most males have two light-emitting devices and wings.

Why do fireflies glow? It turns out that there is a substance called luciferase in fireflies, which will react with oxygen and emit light. When it is happy, it will press more air into the breathing tube and the light will be brighter; If it is unhappy, it won't push air into the pipe, and then the lights will dim or go out completely. Its light has several functions, namely, courtship, illumination, warning and display.

Every day when I come home from school, I will take it out of the box, turn off all the lights in the room, and then take out a book and let it lie on it. The light emitted by fireflies can let me see the words in the book, which is very interesting!

But one day, when I took the firefly out of the box again, I found it was dead. Its belly began to turn black, and the usually shiny light-emitting device turned white. I didn't feed it.

I see, let these little creatures live in the embrace of nature! Let them fully enjoy the fun of life.

This summer vacation, this summer makes people feel very comfortable. My mother and father and I went to my grandmother's house. My grandmother's house was in the country. At night in the country, it was cool and breezy. Unlike cities, the traffic here is particularly noisy, so this one is quiet. You can see the starry sky when you look up. Although the whole sky is black, you can see many small stars. Suddenly, several glowing things flew around in front of my eyes. At first, I thought I was dazzled. Why do stars fly so fast? Later, when I saw it, it turned out to be a firefly. They are small and hovering at low altitude.

My father and I decided to catch some fireflies, because this creature is really hard to see in the city. I asked my grandmother for a mineral water bottle. Most fireflies live in grass. I leaned down slowly, holding a water bottle in my left hand and a small net in my right hand. My grandmother made it for me. I use it to catch butterflies during the day. Fireflies fly very fast and can run away if they are not careful. I have a pair of good eyes. I'm looking for fireflies. Dad has good arm strength. It will catch them. The two of us cooperated in this way, and soon caught two, and then gently put them into the water bottle. Fireflies are really beautiful, especially beautiful.

After observation, I released the fireflies. My father said that creatures should not be trapped because of their love. They belong to themselves, not to this bottle. I think dad is right.

In this magical and beautiful season, how beautiful and enchanting she is during the day, singing and dancing everywhere, pink and green. No wonder Du Fu, a great writer in the Tang Dynasty, praised her enchanting with "birds in the river are above the white, flowers in the mountains are burning", while Yang Wanli, a great writer in the Song Dynasty, praised her children with "infinite lotus leaves in the sky and different colors of lotus flowers in the sun"? Lotus. However, I love the quiet beauty of this person's night.

It is really hot in summer. People often talk about things during the day in the shade of trees. The stars in the sky twinkle, as if to say to them, "Zhang San did something wrong, didn't he?" The beautiful Chang 'e girl is now in Guanghan Palace, holding the Jade Rabbit and silently watching her beloved Hou Yi.

It is beautiful in the lotus pond. A light rain has just passed, and there is little rain on the bud, and the water drops on the lotus leaf are crystal clear. It was the beauty of summer that spilled some pearls on her, huh? There's another voice. Listen, "goo goo". Oh, is it uncle farmer's helper? Frog. Seems to be jealous of Xia Mei's favorite lotus leaf. It jumped on her and the pearl fell into the water. It cried and declared victory. Jump again and dive into the water to find pearls.

Summer is magical and beautiful. Summer nights are quiet and charming.

I love you, summer night.

Summer night is very lively. Insects, birds and the "whirring" sound when the wind blows through the Woods make people lively and quiet.

The moonlight shines on everything, insects sing concerts, and the swaying shadows on the ground are like a painting that no one can understand. Suddenly, a few lights flashed in the shadows of the trees, flickering like candlelight that was about to go out at any time. The light moves down from the shadows of the trees and comes to the moonlight. Oh! Just little fireflies. Fireflies are flying, insects stop singing and watch them fly quietly. Fireflies stay in the sleeping flowers, the faint light shines a little light, and the flowers show color in the dark. Fireflies dance in the dark, flowers cheer them up, insects start singing again, and everything is so natural.

Fireflies look at the mirror on the water, and the fish in the water are scared by them to swim away and shake their tails. Fireflies landed on the tree in dribs and drabs, making the tree look particularly beautiful. Seen from a distance, it looks like a starry sky. The bird perched on the tree was awakened by the light and gave a cry that seemed to be surprised: what is shining on the tree and why it is so dazzling. At dawn, fireflies fell and fell to the ground.

Although the life of fireflies is short, there is only one night, but they don't complain, because they have shown her beauty that night.
