NOEL KING, HOST:
Good morning. I'm Noel King. Here in Washington, D.C., cicadas are this summer's unofficial soundtrack.
(SOUNDBITE OF CICADAS CHIRPING)
KING: In New Jersey, where the bugs have also emerged by the billions after 17 years, David Rothenberg is playing right along.
(SOUNDBITE OF MUSIC)
KING: Rothenberg is fascinated by cicada cycles. He told the CBC if you become a cicada groupie, then you know it's like following the Grateful Dead around. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
