Invasion of Cicadas in the United States

There is a discussion about a rare event of two waves of cicadas emerging in Illinois after a long period, approximately every 200 years. The cicadas crawl out of the ground when the temperature reaches around 65 degrees Fahrenheit, landing on trees and making outdoor activities unpleasant. The invasion of cicadas in Illinois and the entire Midwest is highlighted, with implications remembered from a similar event in 2007.
