Why does the dragonfly love to stay on a certain protruding branch, what is it doing?

Dragonfly: "Can't I rest?" ”

One afternoon, Tao Xingzhi came out of the village and saw a group of children catching dragonflies.

He stopped, lovingly stroked Cuizhen's pigtails and asked, "Cuizhen, do you know what dragonflies eat?" ”

Eat dew. A boy said.

The children scrambled and said, "Eat grass." "Eat leaves. "Eat the dirt. ”

Mr. Tao pulled the children to sit on the ridge and said, "Cuizhen is right." Flies, mosquitoes, and the wretched in the water, it eats them all. Do you think dragonflies are our good friends? ”

The children nodded. Tao Xingzhi took the dragonfly from Cuizhen's hand and held it high. Under the sun, the dragonfly's eyes twinkle and its tail pouts. Mr. Tao asked again: "What is the use of a dragonfly's tail, who knows?" ”

The dragonfly uses its tail to point water in the river. ”

The tail is the one that masters the direction of flight. ”

Tao Xingzhi carefully turned the dragonfly over, pointed to its tail and said, "You see, its tail is segmented, thin and long. It uses its tail to keep its balance and adjust its direction.

It is said that when it is extremely hungry, it will eat off its own tail. However, it will grow again in the future. Then he pointed to the dragonfly's head and said to the children

Its eyes are large and complex, made up of thousands of small eyes that can see bug......s in all directions”

The children listened intently. Tao Xingzhi said in a consultative tone: "Put it away, okay?"

As he spoke, he returned the dragonfly to Cuizhen. Cuizhen looked at her friends, and the children said, "Let it go, let it go, let it go home!"

Cui Zhen opened her little hand and sent the dragonfly upward, and the dragonfly wings flew into the air.

Dragonfly tree, pinyin qīng tíng shù, means the legendary name of the tree.

Source: Tang Duan Chengshi "Youyang Miscellaneous Tales and Wood Chapter": "Lou Yue lives in Changshan, according to the Zen seat. There was a wild woman, holding a tree in her hand, and planting it in the court, saying that this was a dragonfly tree. It is old and fragrant. There was a bird with a bare body and a long tail, and it was always resting on it. ”

Extended information: Dragonflies are a general term for invertebrates, insecta, dragonflies, and suborder Paraptera. The base of the hindwings is slightly larger than the base of the forewings, and the wing veins are slightly different.

When resting on the four wings, lay flat on the sides. The larvae are short and stubby, with rectal gills and no tail gills. There are 3 general departments, including Aeshnidea, Cordulegastroidea, and Libelluloidea, with a total of 11 families.

Flyflies and dragonflies are the most common and are widely distributed throughout China. Dragonflies are carnivorous insects.

They prey on a variety of agricultural, forestry and animal husbandry pests such as flies, mosquitoes, leafhoppers, midges and small butterfly moths. Dragonflies are an important class of natural enemies that are beneficial to humans. "Dragonfly dotting water" is a biological feature of dragonflies laying their eggs in water.

The larvae (larvae) live in water and live for a period that varies depending on the species, ranging from 2 years to 3 to 5 years. It can be used to monitor environmental pollution, and has medicinal, edible and ornamental value.

I love dragonflies because they are very elegant and noble. They have slender bodies and flexible wings, and when they fly, they are as light as feathers, and they resemble a lively bird. They are brightly colored, with green bodies, purple feet, yellow heads, and rainbow-colored butterflies.

Their calls are also very distinctive, chirping, crisp and pleasant, like a moving serenade. They are always flying freely between the blue sky and white clouds, and that feeling of freedom makes me feel refreshed.
