Pinao is the Hawaiian word used to generally identify the damselfly and dragon fly species endemic to Hawai'i.[4]
Description
editAdults may grow up to 45 mm in length and up to 50 mm wingspan wise.[5]
Ecology and habitat
editMajority of the population reside along the Koʻolau Range of Oʻahu.[6] Pools/streams with fish and frogs present prohibit the species from inhabiting these areas.[7] Therefore, they reside above man-made and natural barriers like waterfalls or constructed water diversions, where its predators aren't present.[8]
Status
editThe Megalagrion nigrohamatum is listed as endangered on the state and federal level, due to the introduction of non-native frogs, fish, and birds.[9]
