Mothman was a moth like huge creature reported to be seen in West Virginia between 1966 and 1967. Many people claimed that they saw the huge creature. It was also featured on one of the episodes of 'Weird or What'.
Have you heard of it?
Yes, I saw the movie The Mothman Prophecies with Richard Gere. Interesting film, though I don't believe the phenomenon is a real thing. Brian Dunning did an episode of his Skeptoid podcast that talks about it. http://skeptoid.com/episodes/4159
