After a 17-year wait to mate, expect a lot of noise from the next brood of cicadas, which will start to emerge next month in parts of five states.

Western Maryland, eastern Ohio, southwestern Pennsylvania, northwestern Virginia and most of West Virginia are expected to see the ascension of the so-called Brood V.

There are six species of periodical cicada, three with a 17-year cycle and three with a 13-year cycle. Periodical cicada populations — called broods — are identified by Roman numerals.

“We think of them as the Methuselah of the insect world,” said Gregory Hoover, an ornamental entomologist at Pennsylvania State University.
