Periodical Cicada, Magicicada septendecim (L.)
Other Cicadas Magicicada cassinii (Fisher) and Magicicada septendecula Alexander and Moore (Homoptera: Cicadidae)
Sounds:
Adult females of cicadas injure grapevines by making
ovipositional slits in the canes. The canes then may break at the slits during
the season in which they are made or during the subsequent year. Because of such
breakage, the resultant crop
and vine growth may be affected adversely.
Nymphs of periodical cicadas do not feed to any large extent on
the roots of grape. Once the nymphs emerge from the eggs, they move into the
ground, where they feed on the roots of deciduous trees. These nymphs require 17
years to complete development and emerge from the ground as adult cicadas.
Adults emerge during late May and are present for about six weeks. The adult is
about 1/2 inches long and has clear wings and a da
rk
body accented with orange and red.
Four different broods of cicadas occur in Ohio. Although each brood requires 17 years to complete its life cycle, the broods overlap, and adult cicadas emerge at intervals of two to eight years in different areas of the state.
