Cicada chirps in the rain. Why doesn't it scream on a sunny day?

The chirping of cicadas is not limited by the weather. The male cicada keeps singing every day in order to lure the female cicada to mate. They can't hear their own songs. The male cicadas of each species make three different songs: collective songs, which are regulated by daily weather changes and the songs of other male cicadas; Courtship before mating; The harsh sound made when caught or afraid to fly away.

This male cicada can sing. Its vocal organ is located in the abdominal muscles, and it is covered with an eardrum like a drum. The eardrum vibrates and makes a sound. Because the vocal cord muscles can expand and contract about 65,438+0,000 times per second, and the cover plate and tympanic membrane are empty, which can play a role of * * *, so its singing is particularly loud. The female cicada's musical instrument structure is incomplete and she can't make a sound.
