Thanks for sending your awesome image of the metamorphosis of an Annual Cicada. Annual Cicadas spend several years underground as nymphs, and as they mature, they dig to the surface and molt for the last time, emerging as adult Cicadas. Annual Cicadas appear every year, which distinguished them from Periodical Cicadas. Periodical Cicadas in the genus Magicicada spend 17 years underground as nymphs (13 years in southern states) and they emerge in great numbers in a given year. They are not seen again in that location until the next Brood matures in 17 or 13 years. Earlier this year, we put out a request for Periodical Cicada images from Brood V, which ranges in the states of Ohio, West Virginia, New York, Virginia, Pennsylvania or Maryland, according to Cicada Mania. We did not receive an Brood V images. There are currently 15 active broods being monitored by Cicada Mania, and you can see the predicted emergence schedules on the site.
