I don't know if you find it, the sun shows its face from time to time, and the cicadas cry even louder. This is related to its habits, the cicada prefers to dry and heat, and mostly inhabits tree trunks and branches. Whenever the summer weather is sunny and hot, in the afternoon and evening, the wings of the leaf are often agitated, and the cry of "know, know..." is issued. However, when the weather will turn rainy, due to the sudden increase in the water vapor content in the air, the wings of the cicada are wet, not easy to agitate, and of course, there is no sound.
It is said that there are about three kinds of cicadas in summer, and the "Notes on the Materia Medica" of Liang Tao Hongjing of the Southern Dynasty is detailed in detail: the morning cicada is a small purple-blue color, which is actually the huम (huìgū) of the "cockroach does not know spring and autumn" in the "Getaway"; the subsequent appearance is black and large, and the sound is also sounded by the grasshopper cicada; and finally it is the green and small, late cicada after the autumn, called the earthworm (diāo liáo). This cockroach has a colorful body and is the most beautiful, which is the "mantis" (qín) that the ancients described the beauty as "mantis head moth eyebrow".
Bai Juyi wrote a poem "Smelling Cicadas on the Night of June 3rd", in the Suzhou generation, the cicadas began at the beginning of the sixth month of the lunar calendar every year: "Three nights before the beginning of the month, the first sound of new cicadas." "As far as the Taizhou area is concerned, the current sound of cicadas should also be regarded as early cicadas."
