  1. Equip your Bug Net.
  2. Explore floors 61–79 of the Lava Caves.
  3. Look for a flying moth surrounded by a light smoke cloud.
  4. Swing the net to catch it (missing does not permanently scare it away).

Tips for Finding the Smoke Moth

  • Bug Pheromones are highly recommended. Uncommon Bug Pheromones work especially well and can make the moth appear much more reliably.
  • Save before entering a floor, use a pheromone, and reload if it doesn’t spawn.
  • Some players report better luck on floors with spiral lava layouts or near lamps/walls.
  • Reloading floors (exit and re-enter) is a common method if you’re hunting without pheromones.
  • The Smoke Moth is considered one of the more elusive uncommon insects in the Lava Caves, so patience (or pheromones) helps a lot.
