Cicada calls in the rain. Why doesn't it call in sunny days?

The cicada's singing is not limited by the weather. Male cicadas sing nonstop every day in order to lure female cicadas 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 other male cicadas' songs; Courtship before mating; The harsh sound of being caught or frightened to fly away.

The male cicada can sing. Its vocal organ is located in the abdominal muscle, like a big drum covered with a tympanic membrane. The tympanic membrane vibrates and makes sound. Because the vocal muscle can expand and contract about 1, times per second, the gap between the cover plate and the tympanic membrane can play the role of * * *, so its singing sound is particularly loud. The female cicada's musical instrument structure is incomplete and she can't make a sound.
