Why do cicadas think it will clear up?

There are many agricultural proverbs handed down from ancient times: smell cicadas in the rain and predict sunny days.

Because it must be sultry before it rains, and cicadas will bark when it is sultry, but why do cicadas bark more fiercely when it is hotter? Judging from its living habits.

Among many insects, cicadas are really unusual. Its life has two stages, first in the "underground" and then in the "sky", which are different. The larval stage stays in the cave for about four years. Living in the shadow for a long time, still wrapped in "prison clothes", that is, "mire", suffocating and depressing, you can imagine. Once you climb out of the hole and take off your shell, it is a relief. Oh, the world is so bright and open, with leafy trees and faint green leaves, so it spreads its thin cicada wings and flies to the bushes to choose its home. That kind of happiness is indescribable. The infinite misery of living underground can finally get rid of it. "cicada cicada", the language of cicada, no one can decipher. However, from that kind of excitement, from that kind of loudness, from that kind of urgency, from that kind of eternal octave, it seems that it is not difficult to guess a thing or two. From darkness to light, from cold to warm, its excitement can be imagined. Perhaps it is a tribute to the wandering wind, abundant sunshine, the shadow woven by cool green leaves, a kind of joy and gratitude. "cicada", a thousand words, all in it.

Cicada is in the tall tree. Suck its juice in the shade, moisten your throat and quench your thirst. "Drink don't eat? Smoked cicada. " It lives by drinking drinks. Cicada's black body sticks to the branches, giving people a sense of solemnity and a Zen gesture. Wearing sheer wings, it looks like a girl's gauze skirt. It can fly with open arms, but it is difficult to go far. It is just a short journey from one tree to another. Its seclusion is also quite short. It was so tired that it screamed at the top of its lungs, because desperate singing exhausted its strength. About two weeks later, it "curtain call". Love is shorter. After having sex once, the male dies and the female dies after laying eggs. Four years underground, spent silently; Half a month's "air" is singing wildly and life is burning. This is cicada's life.

So people judge rain according to the cicada's cry!
