It's a natural phenomenon 17 years in the making - Cicada Brood X has begun to emerge from their slumber.
The buzzing bugs will be heard across 15 states, including in the tri-state area.
People have started posting photos to social media of cicada sightings in their backyards throughout the Eastern Seaboard and Midwest.
The cicadas will spend two to four weeks mating, and being eaten by predators.
