Cicada

The 13-year Cicada hasn't been out since 1998. Cicadas live for about five to six weeks, and make that familiar chirping sound, you may recall from the summer of 1998.

Dr. Frank Hale, entomologist at the University of Tennessee Extension, says cicadas are harmless to humans but the females can cause damage to young trees when laying eggs.
