The life habits of cicadas are as follows:

1. The larvae of cicadas live in the soil and have a pair of strong digging front feet. Using the sucking mouthparts to suck the sap from the roots of plants weakens the tree vigor, makes the branches die and affects the growth of trees. Usually stay in the soil for several years or even more than ten years.

2. Male cicadas sing nonstop every day 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 sound before mating.
