Trillions of cicadas are set to emerge across 15 U.S. states this spring, as a colony of insects known as Brood 10 awakens from a 17-year-long hibernation.

The bugs, colloquially but incorrectly known as "locusts," are expected to appear for the first time since 2004 in Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Washington, D.C.
