The cicadas will likely be most active in areas ranging from southern Ohio, Kentucky, Tennessee and parts of western North Carolina, according to P.J. Liesch, director of the UW-Madison Insect Diagnostic Lab. However, people can expect to spot them as far east as Boston and as far west as southern Indiana, Liesch said.
“Based on historical records, we know there’s going to be a little bit of activity in a few counties in Indiana,” he added. “Those would be about the closest to us up in Wisconsin.”
