- Not to be confused with 蛾.
蛾怪 is a powerful flying 敵怪 that spawns during the 日食 event and passes through 物塊s. It can only spawn after all 機械 Boss 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 天兔.
- 斷裂英雄劍和克蘇魯之眼的掉落是相互排斥的, 有 25% 幾率掉落兩樣中的一樣也有 50% 的幾率兩樣都不掉.
- 槍和弓還有法杖很不錯』. 食人魚槍發射的小食人魚會一直攻擊它打到的敵人，同時又會鎖定目標（在正常模式下20-25秒就會被擊敗，在專家模式40-45秒就會被擊敗）. 同樣好的選擇是 巨獸鯊或 邪惡三叉戟 (不計算它的高法力值消耗) , Also 水晶蛇 is a viable choice due to the splash projectiles, or for melee users, any 斷裂英雄劍 made weapon (泰拉刃, 原版斷鋼劍, 原版永夜刃), 悠悠球 such as 克拉肯球 or 克蘇魯之眼.
- Mothron is most vulnerable when it's laying its eggs.
- Mothron is a reference to Mothra from the namesake 1961 movie. The subtle change in its name follows the trend of Terraria enemies' and bosses' names ending with the suffix -ron, such as 骷髏王, 豬龍魚公爵, and 豬龍.
- 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.
