Cassini Periodical Cicada
A 17-year periodical cicada distinguished from related species by its all-black underside and distinctive buzzing call. It often emerges alongside M. septendecim in the same broods.

It nearly eliminated Fraser fir from the highest peaks of the southern Appalachian Mountains.
