HELEN, Ga. -- Campers in north Georgia are getting an earful they didn't expect - the sound of cicadas.
They only emerge every 17 years, and Unicoi State Park near Helen has a brood of hundreds of thousands. The noise echoes through the park. The shells are stuck to walls and trees.
17 years ago when cicadas last emerged, it was 1996. The Olympics were happening in Atlanta and cell phones had antennas.
This round of cicadas will live until mid-June. Their offspring will emerge in 2030 and again, fill the park with "singing cicadas."
The group of cicadas, called a brood, is very localized and have only been spotted near the park. The insects are not expected to make their way into Atlanta.
A fact about cicadas you might not know -- only male cicadas "sing." Unlike crickets, they do not use their legs. Instead, the noise comes through holes in their large abdomen.
