- "...thousands of dark-grey and black moths, some nearly as big as your hand"
- ― 
Moths were nocturnal insects of a kind closely related to butterflies. Bilbo Baggins found them fluttering at nightfall on his first visit to Rivendell. Curiously, they are also mentioned as dwelling in Mirkwood, where the moths were black or dark grey, and grew to a huge size.
 Other versions of the legendarium
In The Tale of Tinúviel, white moths flittered about the head of the dancing Tinúviel, as the evening fell. It is told that Tinúviel "being a fairy minded them not as many of the children of Men do, although she loved not beetles, and spiders will none of the Eldar touch because of Ungweliantë".
 Portrayal in adaptations
- In Peter Jackson's movies, moths are somehow associated with the Eagles; while Gandalf is trapped on the summit of Orthanc, he catches a moth and whispers to it. Later, when confronted by Saruman, the moth reappears; an Eagle (supposedly Gwaihir) arrives and Gandalf escapes on its back.
- Right before the Battle of the Morannon, Gandalf notices a moth flies near him. Then the Eagles appear and help the Free Peoples.
- As Thorin and Company are trapped in a falling tree by the band of Azog and their Wargs, Gandalf uses a moth to summon the Eagles to their aid.
