The Moth is a rare Hardmode enemy that spawns in the Underground Jungle. They fly around very slowly, and upon seeing the player, will direct their attention towards them and attempt to deal damage to them. Upon killing the Moth, there is a chance that it will drop Butterfly Dust if a mechanical boss has been defeated, which is solely used in the creation of Butterfly Wings. They are immune to the Poisoned, Venom and Confused debuffs.
