Noisy Swarms Of Cicadas Return To East Coast This Spring After 17-Year Hibernation

PHILADELPHIA (CBS) — Get ready for a biological phenomenon! And a very loud one.

Massive swarms of cicadas are set to return to the East Coast this spring following a 17-year hibernation.

They’ll start to appear in May, and chances are you’ll hear them.

Their courting and mating sounds can reach 100 decibels, which is as loud as a lawnmower.

They live up to four weeks, then their offspring go back underground for 17 years.
