Everyone is familiar with the cicada, which is the common name for cicadas, and in my hometown, this insect is called the "old spoon". The scientific name of the cicada chrysalis is called cicada monkey, also known as robin's tortoise, robin's monkey, is the picture of this goods:

When I was a child, there has always been a question, that is, robin's this is not a very big insect spawned eggs can be how big? This egg and how to get into the ground below 3 meters, and then lurk for several years, into a chrysalis again climbed out of the ground, complete the cycle of life? With years of doubt, after some investigation, but also consult a study biology students, finally figured out the whole process, and now share it with you.

First of all, the cicadas' wings are the last stage of the creature's life. Retreating from their shells means that they have to usher in the final stage of their lives, mating, reproducing, and then dying.

Male cicadas make a shrill sound to attract the opposite sex, and once the male and female have mated, the females prepare to lay their eggs while the males continue to search for a mate (males are so scummy).

Female cicadas, on the other hand, will start laying eggs when they are well prepared. Female cicadas will choose the most tender part of a tree's branches, that is, the end of a newborn branch, and have their own mouthparts, make many small holes in the branch, and then lay their eggs inside the holes. Then it waits for the end of life itself.

The eggs laid in the branches then continue to develop with the help of nutrients from the branches. Until it develops into a larva. As the weather gets colder, and the nutrients in the branches are absorbed by the cicadas, the branches die until they fall off. As the branches fall off, the cicada larvae fall to the ground.

After that, the larvae will continue to crawl and make holes in the earth. Seeking out nearby roots, they will use their mouthparts to continue their development by sucking the nutrients of the tree from the roots. Crawling deeper and deeper during this time as well, because deeper means less likely to be found and safer.

Cicada larvae will develop in the soil for a long time, some for three years, some for five years, some for seven years, and the longest ones have been developing for more than a decade. It's a long process, and the larvae are slow-moving, but their strong front claws can travel for them by making holes all over the place deep in the soil.

Until they are fully developed, cicada larvae then climb upwards out of the ground, down the trunk of a tree, to a suitable height to complete the act of shedding their shells.

The wings of the robin, which has just finished shedding its shell, are soft. At this time, the robin's body fluids will hold the wings up by filling the thin tubes in the wings, and waiting for the wings to firm up, the fluids will flow back inside the body. If this process is not completed successfully, the cicada that comes out of its shell becomes disabled, resulting in an inability to fly.

Then, a new cycle of life begins. For countless springs and autumns, countless cycles, nature uses its own power to dictate is everything, harmonious and orderly.

Some partners may ask, if the female cicada spawning branch did not fall in how to do? This do not have to worry, because cicadas this insect has a very strong ability to reproduce, in other words there is a numerical advantage! The huge numerical advantage is the guarantee of the survival of their populations.
