Mascot Moth was considered by David Devant to be his masterpiece, which he created in 1905. In full view of the audience and in the center of a lighted stage, a lady (dressed in a moth-like costume) disappears as soon as the conjurer attempts to grasp the her. She immediately vanishes out of sight as she folds her wings in, although the figure is not concealed in any way during the illusion.
The children's writer E. Nesbit featured it in her 1912 play, "The Magician's Heart".
Seigfried & Roy performed the Mascot Moth illusion nightly during their show at the Mirage hotel and casino.
