The larvae of cicadas live in the soil, stinging and sucking the sap from plant roots, weakening the tree and causing the branch tips to die, affecting the growth of the tree. Cicada larvae live in the soil all their lives. When they are about to be feathered, they drill out of the soil surface at dusk and at night, climb to the tree, then grasp the bark and molt and feather. The process of molting begins when a black crack appears on the back of the cicada pupa. The whole process takes about an hour.At the end of June, the larvae begin to feather into adults, with a maximum lifespan of about 60 to 70 days.In late July, the female adults begin to lay eggs, and the egg laying season is the peak of August, with the eggs mostly laid on the tops of the branches that are 4 to 5 millimeters thick.The eggs are laid on the tops of the branches that are 4 to 5 millimeters thick. In the summer in the tree screaming loudly, with a needle prick mouthparts to suck sap, larvae inhabiting the soil, sucking the sap of the roots, harmful to the trees.

Commonly known as "robin", an insect. The largest cicada has a body length of 4 to 4.8 centimeters, and the base of its wings are black and brown. In the summer in the tree screaming loudly, with a needle prick mouthparts sucking sap, larvae inhabiting the soil, sucking the sap of tree roots, harmful to trees. The shells that cicadas shed can be used as medicine. Cicadas are larger plant-sucking insects, usually about five or six centimeters long. Their needle-like hollow mouths can pierce trees and suck the sap. There are also different types of cicadas, which are similar in shape but different in color. Cicadas have three less sensitive eyespots in the middle of each eye, and thin tubes that act as supports are simply distributed on each wing. These are primitive features of an ancient insect species.

The soprano singer in the cicada family is a species known as the "double drummer". It has large ring-shaped vocal organs on both sides of its body, and in the middle of its body is a disk that opens and closes internally and externally. The disk opens and closes very quickly, and the shaking cicada song is produced from it. This sound lacks variety, though it is much louder than the call of the jungle canary.

The cicada nymph spends the first two or three years of its life underground, perhaps longer. During this time, it sucks up fluids from the roots of trees. Then one day it breaks out of the ground and finds a tree to climb on its survival instincts. After several years of slow growth, the cicada nymph climbs out of the ground as a store of energy. The front claws it uses to dig holes can also be used to climb. The molting process begins when a black crack appears on the cicada nymph's back. Molting is controlled by a hormone. The front legs of the cicada nymph are hooked so that it can hang securely from the tree when the adult emerges from its empty shell. It is very important that the cicada nymph faces the tree vertically. This is for the proper development of the adult's two wings, otherwise the wings will develop deformities. The cicada uses the shell of the nymph as a base and slowly frees itself, as if climbing out of a suit of armor. The whole process takes about an hour. Once the cicada's upper body is free, it hangs upside down so that its wings unfold. At this stage, the cicada's wings are soft, and they are spread out by means of the body fluid tubes in them. The tubes are pressurized by a liquid that causes the wings to spread. By the time the fluid is pumped back into the cicada, the wings have hardened. If a cicada's wings are disturbed while they are spreading, the cicada will be crippled for life and may not be able to fly at all.
