For example, crickets can use the friction of the wings issued by the sound of music like the general crisp and clear to show their various "feelings". When the male and female get along, the sound tone is light and quiet, as if lovers whispering; when alone, it will send out a high-pitched strong sound to attract friends.

They can effectively transmit information, and play a very important role in animal life. For animals, the broad range of communication is unimaginable to humans.
