The sound of summer is coming.
One of the largest broods of cicadas is expected to hatch in the coming weeks for the first time in 17 years, and it won’t be long before the bug’s distinct chirp inundates New Jersey. The coming hatch has

entomologists giddy, while others recoil in disgust.
It has also produced a citizen science project aimed at tracking the bug’s emergence.
"It’s fascinating," said Ellen Horne, executive producer of WNYC’s RadioLab, which has launched the online project. "It’s disgusting and it’s sudden and one of those things that has almost a biblical scope and thrust to it. There’s such a weirdness to it being a 17-year cycle. At the heart, they’re very mysterious."
Horne is right: Cicadas are a mystery of evolution for scientists.
They emerge from the ground in cycles, once every 13 or 17 years, when the soil temperature at about 8 inches below the surface reaches a steady 64 degrees. Within hours of appearing, the bugs go through a metamorphosis, transforming from a flightless, slow-moving nymph stage into a large, flying insect.
