WATCH: Billions of cicadas are set to emerge from the ground in 15 states from Georgia to New York and over to the Mississippi River. After spending 17 years underground, the Brood X cicada nymphs will crawl out of the ground, molt into adults and mate, all in a four-week period. For some humans, like University of Maryland entomologist Mike Raupp, it offers a chance to enjoy rare delicacies like cicada cookies and tacos. | PBS NewsHour
