WASHINGTON - MAY 16: Newly emerged adult cicadas dry their wings May 16, 2004 at a park in Washington, DC. After 17-years of living below ground, billions of cicadas belonging to Brood X begin to emerge across much of the eastern United States. The cicadas shed their larval skin, spread their wings, and fly out to mate making a tremendous noise in the process. (Photo by Alex Wong/Getty Images)
The big green bugs that make a deafening sound are back.
According to the Gardener's Network, Brood X cicadas span the following states: Georgia, North Carolina, Ohio, Pennsylvania, Tennessee, New York, Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, Virginia and West Virginia.
Whichever kind they are, cicadas don't bite and don't cause much harm to trees. Their loud sounds and startling movements is all most will have to deal with.
