Vampire Caterpillar (23rd November 1904, Edinburgh, Scotland)

While walking along a street in Edinburgh, Godfrey H. Anderson claimed to have spied a bizarre 'something' that rose out a gutter and sprung up towards the throat of a nearby horse. According to Anderson's description, the creature was a 'vague black shape about four feet long and two and a half feet high… like an hourglass and moved like a huge caterpillar.' The horse reared up in terror, and its phantasmal attacker promptly vanished.
