The big, loud bugs pop up every 17 years in Northern Illinois. They've already surfaced in the Chicago area this year. Master gardners in the Stateline say we could see the cicadas any day now... crawling out of the ground and climbing up shrubs and trees to mate. The gardners gave us an idea of where the cicadas will strike. "We'll see a broad covering of cicadas, especially in some of the older areas. The newer developments where the soils have been disrupted may not see as many," says Meghan Bowe with the University of Illinois Extension Office in Rockford. Once they arrive, Bowe says the cicadas will be around the area for three to four weeks. And that loud noise you'll hear....that's the male cicadas trying to attract the females.
