A Cicada skin That we found

The Life Cycle of a Cicada

While the Cicada life span may be as long as 17 years, they spend almost all of their lives underground. Cicada nymphs emerge from the ground in periodic cycles. They climb up trees and quickly shed their skins(molt). An adult, flying cicada emerges. The adult Cicadas' entire purpose in life is to mate and produce offspring. You can hear the males' mating "song" from early morning to nightfall. In heavily infested areas, the noise can be quite disturbing. About five to ten days after mating, the female lands on twigs of deciduous trees, cuts slits in them, and lays her eggs in the slit.

Adults do not eat. Rather, damage to trees is caused by the adult female as she cuts slices into twigs to lay her eggs. Shortly after mating, the male Cicada dies.

The eggs hatch, producing tiny nymphs that fall to the ground. These nymphs burrow into the soil and feast on underground roots. They remain there for years, slowly growing, until their periodic cycle calls them to emerge again as adults.
