Цикада: существо, которое спит под землёй 17 лет и просыпается всё разом

It's a hot summer day somewhere in the south. And the air around us is literally ringing. From all sides, from the treetops, from the thickets, comes a powerful, pulsating, deafening roar that never stops. It's deafening, everywhere, audible for hundreds of meters. But no matter how hard you peer into the foliage, the source is almost invisible. We constantly hear this creature and almost never see it. It's a cicada. And behind its call lies one of the most astonishing stories in the entire insect world. Now prepare to be transformed. Because right now, as you watch this, underground, in complete darkness, billions of these creatures are silently counting down.
