Though there are more than 3,000 species of cicadas, according to National Geographic, only a few spend large periods of their life underground, including the 17-year cicadas and the 13-year cicadas.

Cicadas don't pose a threat to humans -- they don't bite or sting. However, they can damage young trees by feeding and laying eggs.
