Megalagrion nesiotes is a species of damselfly in the family Coenagrionidae. Its common name is flying earwig Hawaiian damselfly. In the past, the flying earwig Hawaiian damselfly lived on the islands of Hawaii and Maui, in the U.S. state of Hawaii. Currently, there is only one population left in east Maui. Limited distribution and small population size make this species especially vulnerable to habitat loss and exotic species invasion. The flying earwig Hawaiian damselfly was last found in 2005. Little is known about this species because of the lack of observation. In 2010, the species was federally listed as an endangered species in the United States.
