Billions of cicadas set to invade East Coast this spring // The noise can has been compared to a New York subway train, and there will be no escape from it as the bugs hatch again after 17 years.

Each population of cicadas that emerges in the same year is called a brood. These brood maps identify the approximate locations where each of the 15 periodical cicada broods emerge. The maps combine the data of C. L. Marlatt (1923), C. Simon (1988), and unpublished data. Broods I-XIV represent 17-year cicadas; the remaining broods emerge in 13-year cycles.

Magicicada periodical cicada by alexanderwild: Characterized by red compound eyes, cicadas in the genus Magicicada spend 17 years (or, more rarely, 13 years) maturing underground before emerging en masse to mate. These emergences take place in May or June and involve several species, each with a different song. http://boingboing.net/2014/06/16/pretty-portraits-of-periodical.html #Insects #Periodical_Cicada #Magicicada #Brood_III
