The Great Eastern Brood cicadas are expected to return to New Jersey after 17 years, and billions of cicadas will begin to emerge across much of the eastern United States mid-May, according to researchers at Rutgers.

The cicadas will stick around until late June, after trees grow leaves.

After shedding their larval skins, males climb to treetops and make loud noises, hoping to attract females to mate with, who lay their eggs there. Once the eggs hatch, the offspring head back into the ground for another 17 years, until 2038.

The last time the state saw a swarm of cicadas was 2013.
