Why do cicadas have so many shells when they shed their shells?

The golden cicada is also known as: cicada molt, know the skin, insect retreat, fairy clothes. It is the shedding shell of the cicada insect black grasshopper when it emerges. Its main production areas are Shandong, Henan, Hebei, Hubei, Jiangsu, Sichuan, Anhui and other places, of which Shandong is the main mass production area.

Cicadas are generally shelled at the end of June. It takes several years for cicadas to go from eggs to adults, and they have to go through 5 molts in their lives, 4 of which are in the soil, and the last time is on the tree, and they come out of the shell from the cicada chrysalis and become adults. Repentance.

The surface of the cicada has a relatively hard skin, which can prevent damage from the outside world, but limits the growth of the larvae's body, and the larvae have to shed their shells often in order to grow.

When the back of the cicada chrysalis cracks a hole, the cicada begins to shed its shell, it takes about half an hour to completely come out of the shell, the soft wings slowly, the cicada at this time the whole body is soft, pale green, the body slowly turns black over time, the wings become white and hard, and the higher it climbs, it can fly after dawn.

The cicada has a hard shell, but at a certain time it will shed its shell, mainly because the shell prevents the cicada from landing or further growth. In fact, the cicada is a very peculiar animal, it has no bone structure, so its shell plays a supporting role in the cicada, but in the development process of the cicada, due to the continuous growth, the cicada's shell is equivalent to human clothes, there will always be a small day, then the cicada must shed the small shell, in order to grow better.

Normally, the cicada's life needs to go through four stages, the first stage is the egg, the second stage is to hatch into the larva, the third stage is to become a silkworm pupae, and the fourth stage is to enter the adult. The molting of cicadas begins at the stage of silkworm chrysalis, and the process of growing from small cicadas to large cicadas needs to go through four molting processes.

The time of molting is generally around the summer solstice, and cicadas often hear cicadas in summer, which is the summer of memory when I was a child. At night around the summer solstice, the cicada will quietly shed the shell on its body, and when it just falls off, the cicada will become very soft, as if there is no shell, but after a while, the shell of the cicada hole will slowly become very hard.

The meaning of molting the cicada actually shows that the cicada is still growing healthily when it molts, this is the process of cicada development, if the shell of the cicada is regarded as its clothes, every certain age, the clothes will become smaller, and it can no longer fit the body of the cicada, then at this time you need to buy new clothes, and human beings are the same, different ages need to buy different clothes, especially during the growth and development, you may not be able to wear the clothes you bought a few months ago.

If the cicada feels that its shell can no longer contain its body, it is time to molt. Therefore, molting is a very important step for cicadas.

Cicadas are unique to the insect kingdom, and shedding shells is an important physiological process during their life cycle. After hatching, cicada larvae begin to live underground or in tree trunks, and continue to undergo the molting process until they become adults. Cicadas shed their shells due to a complex set of biological reasons and ecological adaptability.

First of all, cicadas shed their shells for growth and development. At the larval stage, they gradually increase in size, and the exoskeleton becomes narrow and unadapted to the new body shape. Hulling allows cicadas to shed their tight shells by molting their skins and obtaining a new exoskeleton that is more spacious and suitable for their own development.

Secondly, cicadas shed their shells to adapt to changes in the external environment. Cicadas are of a wide variety of species, widely distributed, and live in a variety of different ecological environments. For example, common cicada species include underground cicadas, trunk cicadas, and branch cicadas.

When there are changes in the external environment, such as changes in temperature, humidity, food, and predators, cicadas adapt to these changes by molting. The cicada's new exoskeleton is generally more heat-insulated, food-resistant, and resistant to predator attacks than its predecessors, thus protecting their survival and reproduction.

In addition, cicada shelling is also closely related to reproductive behavior. In some species of cicadas, adults prepare a special molting site on a branch or other support that serves as a place for their courtship. The site is usually made up of the remains of the last molt of the larval stage, which serves as a stage for the adults.

At this time, the male cicadas attract the female cicadas to mate by making specific calls. Therefore, cicada shedding can be said to be a sign of cicada maturity, self-presentation, and reproduction.

In conclusion, cicada shelling is a complex and important biological process, which is closely related to individual growth and development, environmental adaptation and reproductive behavior. It demonstrates the cicada's unique lifestyle and adaptability as an insect. For understanding the ecological habits and biological characteristics of cicadas, shelling is an important object of study and observation.
