On the day of the summer, the Shanghai Central Meteorological Observatory updated the high temperature yellow warning signal as a high temperature orange warning signal at 12:43 on July 7, 2021. In such a sweltering heat, the one who shouts the most is counted on the tree.
Also known as cicadas, Shanghainese people call it "wild wuzi (night beard)". If a little more detailed, by type. They also have their own names:
Follow the color
Black: Wild umachi
Color: Mu chicken chicken
Green: Yesta
Follow the sound
A vocalizer (male cicada) on the abdomen will call:
castanet
The absence of a vocalizer on the abdomen (female cicadas) does not bark:
Dumb board
The green "Yesta", the original official name is "Mongolian Cold Cicada", the black "Wild Wuzi" is called "Black Grasshopper", and the small and gray one is called "Cockroach".
The earliest call in the summer is the wild umago, the summer is almost autumn when the chickens join, and the late autumn coolness is the most noisy time for Yes.
Heilibao Island Cicada also known as "Ye Cicada" was photographed in Guizhou in 2017
The cicada will chirp, its pronouncement apparatus in the abdominal muscles, like a large drum covered with a layer of eardrum, the eardrum is vibrated and makes a sound, because the vocal muscle can stretch and contract about 10,000 times per second, the cover plate and the eardrum are empty, can play a resonant role, so its sound is particularly loud. But don't forget that the sounder is only available in male cicadas, and females are "dumb".
Cicadas live in temperate to tropical regions of the world (about 2,000 species of cicadas have been recorded). When the body temperature is overheated, excess water is discharged from the back plate, which in turn achieves the effect of cooling and heat dissipation. This is why we always misunderstand that "knowing" will urinate.
