Get ready to be swarmed!
Cicadas, part of a group called Brood X, are expected to appear in 18 states over the next few weeks. They have been underground waiting for this moment since 2004 (that's 17 years!).
The bugs will emerge at different times across the country depending on the right temperature. The ideal soil temperature for cicadas is about 64 degrees.
We can expect to see them all along the East Coast and in many Midwest states including Illinois, Wisconsin, Indiana and Michigan.
According to the NY Times, they aren't dangerous to humans, but that they feed off plants and can injure small trees and shrubs.
