Moth

Not to be confused with Mothron.

The Moth is a rare Hardmode mob that spawns in the Underground Jungle. 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.

Tips
Despite having 1000 HP, Moth can easily be killed with any hardmode weapons, making the Butterfly Wings easily obtainable. In addition, the butterfly wings go further than the Angel or Demon wings, and emit light.
