John Cooley of Magicicada.org (don’t forget to report your sightings) wrote to tell us about the large emergence of periodical cicadas in Tennessee. See the picture below taken by John in Warriors’ Path State Park, TN.
The mystery is defining which brood these cicadas belong to. Are they brood XIV stragglers; are they an undocumented pocket of Brood I cicadas; or are they cicadas that straggled long ago, but finally established a healthy population in synch with Brood I? For now, it’s a puzzle.

See John’s map on Magicicada.org that documents the 2012 Tennessee cicadas.
Update: A similar emergence occurred in 1995 (17 years ago) in the Warriors’ Path State Park, TN area. This could be an undocumented area of Brood I cicadas.
