Moths are a species of winged insect resembling a butterfly. In RuneScape, moths are groups of non-player characters found in Dorgesh-Kaan, a subterranean city beneath Misthalin. They can also be seen in various other places, although usually they are not given the traits of an NPC; for instance, they can be seen flying around lamps in areas such as the Tree Gnome Stronghold.
The moths found in Dorgesh-Kaan are small and resemble those found in the real world. However, much larger species of moth are said to inhabit the cave system surrounding the city; Zanik of the Dorgeshuun possesses several mounted moths within her home.
