Alessian terror moth
From Wookieepedia, the Star Wars wiki.
Found on Tarsa, enormous Alessian terror moths would swarm around any light source. Luke Skywalker used the moths to scare a city-boy storm trooper guarding a Imperial relay base afraid of bugs by turning off every light source in an area but one.[1] The moths presumable originated on Alessia, the moon of Tarsa.[2]
