CINCINNATI (AP) - A group of cicadas is emerging in southern Ohio after 13 years underground, according to two researchers who study the insect.
The Cincinnati Enquirer reports that a College of Mount St. Joseph professor and another researcher say they found the cicadas this week at the Crooked Run Nature Preserve in Clermont County east of Cincinnati.
Some cicadas emerge annually. But the researchers say periodical cicadas are only found in the eastern half of the United States and emerge typically every 13 to 17 years.
The groups that emerge are called broods.
Cicadas spend most of their lives underground, living by sucking fluids from plant roots. The mate and die within weeks of emerging.
Cicadas in large numbers can create a loud buzzing racket and can harm young trees.
