The cicada food is mainly the sap of trees, as well as the sap of crops or other plants. Whenever the cicada sings about thirst and hunger, he always uses his hard, thin mouthparts to suck juice into the tree trunk all day long, sucking a lot of nutrition and water into his body to prolong his life.

His larvae stomp under the soil and absorb the sap from the heel of the tree. if there are many larvae sucking on the juice, then the tree will die for a long time and the cicada will stay in the soil for as long as three years until the adults come out to shell and become cicadas.

Cicadas insert the needle-like mouth under the head into the branches of the tree to suck plant sap to sustain life. After mating, the female cicada also uses its spear-shaped ovipositor to insert into the woody part of the young branch to lay eggs, which is a hole, often making many small holes in a branch.

After the cicada laid eggs, it pierced the lower part of the branch with a circle of toughness, so that the upper part of the branch could not get water and nourishment, and finally withered, and the withered branch fell to the ground as soon as the wind blew.

A few weeks later, the cicada completed the task of passing on the family line and died. The eggs hatch into nymphs, drill into the soil and begin to live a long underground life. They suck the sap from the roots underground for a living, from 2023 to as many as 17 years. After living underground enough, they climb out of the ground, and then "golden cicadas get out of their shells" and feather into cicadas.
