Life habits of cicadas:

Whenever it is hot in midsummer, the heat wave is often accompanied by the sound of knowing, knowing and knowing. Male cicadas sing by contracting the vocal muscles in the abdomen, vibrating the eardrum and making sounds. Singing is a courtship. The female cicada heard the chirping of the male cicada flying dozens of meters away and went to meet him. The male cicada died quietly after completing the reproductive task. But the eggs fall off with the bark or wind and rain, and fall into the soil, and the larvae develop into the deep soil and begin their life history.

Cicada spends all her life underground, ranging from 3 to 5 years to 10 years. It grows underground by sucking the sap from the roots. When it matures, it drills out of the soil, climbs up the trunk, finally sloughs, flies to the tree and starts to sing.
