We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: TBD -- Update: Fri 10/20 11pm UTC - We have encountered some unexpected issues. Our staff is working around the clock to complete this process as quickly as possible. Thank you for your patience.

Not to be confused with Moth.

Mothron is a powerful flying enemy that spawns during the Solar Eclipse event and passes through blocks. It can only spawn after all Mechanical Bosses have been defeated. Mothron attacks by lunging at the player. Occasionally it lands on blocks to lay several Mothron Eggs that will spawn Baby Mothrons if they are not destroyed in time, much like Lepus.

Notes[edit | edit source]

  • Broken Hero Sword and The Eye of Cthulhu item drops are mutually exclusive, i.e. there is 25% chance for either item and 50% chance for none of them.

Tips[edit | edit source]

Trivia[edit | edit source]

  • Mothron is a reference to Mothra from the namesake 1961 movie.[1] The subtle change in its name follows the trend of Terraria enemies' and bosses' names ending with the suffix -ron, such as Skeletron, Duke Fishron, and Pigron.
  • If the Eclipse finishes, or all players die, Mothron floats up to the sky and despawns, similar to the Martian Saucer and Pumpkin/Frost Moon Event Bosses. In addition, it becomes invincible after the end of the Eclipse.
