5. In 2007, Brood XIII reemerged in Illinois. After weeks of news reports about the cicadas' return, people in some of the suburban areas surrounding Chicago were disappointed when no cicadas appeared in their neighborhoods. In areas like state parks, though, the air was absolutely swarming

• Cicadas don't migrate. The adults rarely travel more than a quarter of a mile from where they
first emerged as nymphs.

• These Magicicada nymphs spend 17 years living several feet underground.

• Nymphs molt in trees, and the adults lay eggs in tree branches.
