Sorry, no "informed opinion" here, but here's my uninformed opinion: I believe the "mothman" is a non-physical being, although it might be able to manifest physically (see R. Bruce's posts about spiritual/astral beings that can manfiest themselves physically for more info on this...I can provide the link to this info upon request). I believe the film that recently came out in regards to the mothman was decent in it's depiction of this particular neg enitity which has appeared various times.
