The Mothman is a creature reportedly seen in the Charleston and Point Pleasant areas of West Virginia from November 12, 1966, to December 1967. Most observers describe the Mothman as a winged man-sized creature with large reflective red eyes and large wings. The creature was sometimes reported as having no head, with its eyes set into its chest.
A number of hypotheses have been presented to explain eyewitness accounts, ranging from misidentification and coincidence, to paranormal phenomena and conspiracy theories.
If you're interested in the Mothman, check out The Mothman Prophecies starring Richard Gere as well. I had to make a thread on this after watching Monsterquest who finally made an episode about the Mothman!
