Gigelorum

Gigelorum is an insect of Scottish folklore. It was believed to be the smallest creature. No description or information is available about it except that it inhabits the ear of a mite.
Speculation exists that it may be based upon the tiniest insect that can be discerned by people possessing excellent eyesight, the giolcam-daobhram, which is described as "an animalcule, the smallest supposable living thing". Ronald Black, a one time Celtic studies lecturer, author and journalist, suggests that the creature could be a figment of the imagination of folklorist and Tiree minister John Gregorson Campbell as he could trace no authoritative sources for it.
