Cicada carcasses are seen at the base of a tree in Elmhurst, Ill., Thursday, July 5, 2007, as the periodical bugs die off, not set to return for another 17 years. While established towns such as Elmhurst, Villa Park, Westmont and Hinsdale heard the deafening roar of cicadas' mating calls, entomologists say that the turnout of Brood XIII, although strong, was spottier and smaller than expected in some areas, likely because of land development over the past 17 years.
