CATDOLL : CATDOLL: Introduction to Zhiliao

Cicadas spend their entire lives sucking sap from tree branches. They rely on their needle-like mouthparts to pierce the branches to take in food - sap (tree pulp). Whenever the cicada is thirsty or hungry, it will use its hard mouthparts to insert itself into the tree trunk and suck sap all day long, absorbing large amounts of nutrients and water into its body to prolong its life.

Cicadas grow in the soil before they mature, and then slowly dig holes and crawl on tree trunks. If you find a hole with thin mud, there must be young cicadas in it. Cicadas shed their shells at night while lying on the tree trunks, and after shedding the shells they have wings.

Cicada larvae live in the soil and have a pair of strong digging forelegs. They use their piercing-sucking mouthparts to suck sap from the roots of plants, weakening the tree, causing branches to die and affecting tree growth.

They usually stay in the soil for several years or even more than ten years, such as 3 years, 5 years, and 17 years. These numbers have one thing in common: they are all prime numbers. This is because prime numbers have very few factors, which can prevent them from coming out of the soil with other cicadas to compete for territory and food.

When the pupa is about to molt, it emerges from the soil at dusk or at night, climbs up a tree, and then grasps the bark and molts. When a black crack appears on the back of the cicada pupa, the molting process begins. The head comes out first, followed by the green body and wrinkled wings. It stays for a while to harden the wings and darken their color, and then it starts to take off. The whole process takes about an hour.

Reproduction of cicadas:

The life of a cicada is mainly divided into three stages: eggs, larvae and adults. The eggs of cicadas are laid on branches, and the larvae live underground. After four years of underground life, the adults will climb onto branches. The male adults will complete the mating task as soon as possible and then die soon.

The female cicada will lay four to eight eggs on the branch, and soon the female cicada will die. Both male and female cicadas will die soon after completing their reproductive mission.

Commonly known as "cicada", it is an insect. The largest cicada is 4 to 4.8 cm long, with dark brown wings. In summer, it makes loud calls on trees and sucks sap with its needle-like mouthparts. The larvae live in the soil and suck sap from the roots, which is harmful to the trees. The shells shed by cicadas can be used as medicine.

Cicadas are large plant-sucking insects, usually about four or five centimeters long. They have a hollow, needle-like mouth that can pierce into trees and suck sap. There are different species of cicadas, which are similar in shape but different in color. Cicadas have three insensitive eye spots between their eyes, and their wings are simply covered with supporting tubes. These are primitive features of ancient insect populations.

The high-pitched singer of the cicada family is a species called the "double drummer." It has large circular sound-producing organs on both sides of its body, and a disc in the middle that can open and close inwards. The disc opens and closes very quickly, producing the trembling cicada chirp. This sound lacks variation, but is much louder than the call of a jungle canary.

The cicada pupa spends the first two or three years of its life underground, or perhaps even longer. During this time, it sucks liquid from the roots of trees. Then one day it breaks out of the ground and finds a tree to climb up based on its survival instinct. After several years of slow growth, the cicada pupa crawls out of the ground as a storage of energy. Its front claws, which it uses to dig holes, can also be used for climbing.

When a black crack appears on the back of the cicada pupa, the molting process begins. Molting is controlled by a hormone. The front legs of the cicada pupa are hooked so that when the adult insect emerges from the empty shell, it can hang firmly on the tree. It is very important that the cicada pupa faces the tree vertically. This is for the normal development of the adult's wings, otherwise the wings will develop deformed. The cicada uses the pupa shell as a base and slowly frees itself, like crawling out of a suit of armor. The whole process takes about an hour.

When the cicada's upper body is free, it hangs upside down again to spread its wings. At this stage, the cicada's wings are very soft, and they are spread out by the body fluid tubes inside. The body fluid tubes are used to stretch the wings. When the fluid is pumped back into the cicada's body, the wings have already been spread out and become hard. If a cicada's wings are disturbed during the process of spreading, the cicada will be disabled for life and may not be able to fly at all.

Fun of Cicada

Since ancient times, people have been most interested in cicadas for their chirping. Poets and writers have sung praises of cicadas, and used their chirping to express their noble sentiments. Some even keep cicadas in small and exquisite cages and place them in their rooms to listen to their chirping for pleasure. Indeed, from the spring when white flowers bloom to the autumn when green leaves wither, cicadas have been tirelessly singing one brisk cicada song after another for people with a brisk and soothing tune, without any Chinese or Western musical instrument accompaniment, adding a strong affection to nature. No wonder people call them "insect musicians" and "singers of nature."

People are intoxicated by the sound of cicadas, but forget their nature. Do you know that when cicadas land on branches and sing loudly, while using their sharp mouthparts to pierce the bark to suck the sap, various thirsty ants, flies, beetles, etc. will come to suck the sap. The cicada will fly to another tree and open another "spring" to continue to provide them with drinks. In this way, if a tree is pierced by cicadas with more than a dozen holes, the branches will be drained and withered and die. It can be seen that cicadas are a big pest of trees.

The cicada that can sing is the male cicada. Its sound organ is at the base of the abdomen, like a drum covered with a tympanic membrane. The tympanic membrane vibrates and makes sounds. Since the sound muscle can expand and contract about 10,000 times per second, the space between the cover and the tympanic membrane can resonate, so its sound is particularly loud. And it can use different tones in turn to sing passionately. The female cicada's musical instrument is not fully constructed and cannot make sounds, so it is a "dumb cicada."

Male cicadas sing non-stop every day to lure female cicadas for mating. The calls of male cicadas sound like a beautiful music to female cicadas. After mating and fertilization, the female cicada uses its sword-like ovipositor to pierce a row of small holes on the branches and lays eggs in the holes. After a few weeks, the male and female cicadas die.

Why do male cicadas chirp? It turns out that the two small discs on the belly of the cicada are called sound covers. There is a transparent film inside the sound cover, which is called a valve. In fact, it is the valve that makes the sound. People use loudspeakers to amplify their voices. The sound cover is like the loudspeaker of the cicada, which contracts and amplifies the sound, making a sound of "zhi-le, zhi-le". Only male cicadas can chirp. Female cicadas do not have sound covers and valves on their bellies, so they cannot chirp.

The tiny larvae hatch from the eggs and stay on the branches. The autumn wind blows them to the ground. Once on the ground, they immediately look for soft soil and drill down to the roots of trees to suck the sap of the roots to survive. It takes two to three years at least, and more than ten years at most. From larvae to adults, they have to go through five moltings, four of which are done underground, and the last one is to drill out of the soil and climb up the tree to shed the dry light yellow shell (this is the cicada shell) to become an adult. It can be seen that cicadas are insects that cannot see the sun. Although they have a long lifespan, they rarely live in the sun and spend almost their entire lives underground in the dark. It is a pity.

Cicadas have two pairs of membranous wings with hard wing veins. When they rest, they always cover their backs with their wings. Cicadas rarely fly freely. They only fly from one tree to another when they are feeding or being harassed. Interestingly, cicadas can sing with musical instruments while sucking juice with straws. Eating and singing do not interfere with each other. The chirping of cicadas can predict the weather. If cicadas start singing loudly at the top of a tree very early, it tells people that "it is very hot today."

Cicadas are a type of insect of the order Homoptera. There are many species, and there are 120 species in my country. The male cicada has a sound-making organ in its abdomen, which can continuously make loud sounds; although the female cicada also has a sound-making organ in its abdomen, it cannot make any sound. When summer comes, the male cicada will stand on the tree and chirp endlessly, and the sound can be heard from far away. It is precisely because of its sound that it is called a cicada. There are songs and literary works with the same name.
