The Bonin damselfly is a small damselfly found only in the Ogasawara Islands, with a slender, bluish body. It lives near waterside plants and eats tiny insects. Its numbers have fallen due to introduced lizards and other predators, and it is protected as an island-endemic insect and Natural Monument.
