Cicadas may live underground for years to decades before reaching the ground, some for three to five years, and some for 17 years. Cicada larvae live in the soil and suck the juice from the roots of plants for a living. When they are about to emerge, they will climb the tree and wait for molting and emergence.

Cicadas have to live underground for several years before they can reach the ground.

The emergence process of cicadas lasts about an hour. During eclosion, there is a crack in the back of the cicada pupa, and then the head is slowly exposed, and then the body and wings are gradually exposed. Stop for a minute, wait for the wings to harden and the color to deepen, and he can take off.

When summer comes, cicada larvae begin to emerge into adults, and their life span is generally about 60 to 70 days. In most cases, female adults begin to lay eggs in late July, and the peak of laying eggs is in early and middle August, and eggs are usually laid on branches.
