Tibicen davisi
Loblolly pine, red oak, tulip poplar, sasafrass forest
Found this specimen dead in a flowerpot. Cleaned off the white (fungus?) to get a better look at the colors.
Nice series of pic's!!
Your cicada is actually T. auletes the largest eastern cicada species.
KEY CHARACTER: T. auletes is heavily dusted with white wax, a.k.a. "pruinosity", as seen here in your pic's.
