Moth in the New Line film
Moths were insects of Middle Earth who had beautiful wings. Grey and black moths lived in Mirkwood and were viewed by Thorin and Company. In the War of the the Ring, Moths helped Eagles by being their messengers. A Luna Moth helped Gandalf escape from the wizard Saruman. The same Luna Moth told Gandalf that the Eagles were coming to the West's aid in the Battle at the Black Gate.
