The Moon Moth is a passive Mob exclusive to Don't Starve Together and introduced in Return of Them. They spawn after a Lune Tree is chopped down, and behave much like Butterflies. After being caught with a Bug Net, they can be planted to produce a Lune Tree sapling, and are the only method of replanting Lune Trees. Unlike Butterflies, Moon Moths will starve outside of the inventory after approximately 4 minutes. If chopping Lune Trees, it's advised to have a Bug Net ready if one intends on replanting them.
Moon Moth inside the player's inventory will starve in 2 days unless fed. They can be fed with any Vegetable. When flying they emit enough light to prevent Charlie from attacking.
