Moth

The Moth is a rare mob that spawns in the Underground Jungle once the Wall of Flesh has been defeated. Upon killing the Moth, there is a chance that it will drop Butterfly Dust, which is used in the creation of Butterfly Wings. They are immune to the Poisoned, Venom and Confused debuffs. It is sometimes considered a miniboss due to it's high health and difficulty to newer hardmode players.
