New Brunswick, N.J. (March 18, 2021) – Rutgers University–New Brunswick entomologist George C. Hamilton is available for interviews on the upcoming emergence of 17-year cicadas in New Jersey. The big, noisy insects appear suddenly in late May or early June.

“This spring, we will again see the emergence of Brood X of the periodical cicada. When it last emerged 17 years ago, high populations were seen in several New Jersey locations, including the Princeton area,” said Hamilton, a professor who chairs the Department of Entomology in the School of Environmental and Biological Sciences. “Assuming their habitat hasn't dramatically changed during the last 17 years, we should see similar numbers this year. Fortunately, they do little serious damage to trees and ornamentals except potentially in nurseries due to egg laying behavior. However, they can be a nuisance because of the large numbers that can potentially emerge and the daylong noise they create while trying to attract mates.”
