A moth is a flying insect closely related to the butterfly. In 1991 some moths were found in the Hogwarts Library. During the summer holidays of 1995, 12 Grimmauld Place was likely infested with moths from long neglect; the curtains were described as being "moth-eaten." On 1 August, 1997 during the Wedding of William Weasley and Fleur Delacour, as night approached, moths began to swoop under the canopy.
