1. The larvae of cicadas live in the soil and have a pair of strong digging front feet. Use the sucking mouthparts to suck the juice of plant roots.

2. When you are about to emerge, drill out the surface at dusk and at night, climb to the tree, and then grasp the bark and molt and emerge.

at the end of March and June, the larvae began to emerge as adults, and the newly emerged cicadas were green, and the longest life span was about 6 ~ 7 days. In late July, female adults began to lay eggs, and the peak of laying eggs was in early and middle August, and most eggs were laid on branches with a thickness of 4 ~ 5 mm. Larvae will not hatch until the second year, and then live in the soil for several years or even more than ten years before they break out.

The role of cicadas

Cicada provides a link in the food chain between trees and animals, and defines an animal as any animal that eats cicadas. Animals like cicadas, and cicadas are a feast in their lives. Trees feed on the nutrients in the sun and soil, cicadas feed on trees, animals feed on cicadas, and predators (wolves, foxes, bears, cats and people) feed on animals. The large number of cicadas leads to a sharp increase in the number of animals, which in turn benefits predators.

Periodic cicadas are parasites of trees, more specifically, parasites of deciduous trees. Cicadas provide services for trees by pruning branches. Cicada lays eggs on branches, and weak branches wither and die. The tree benefits from this situation because it doesn't have to waste energy on weak or sick branches.
