Species Description
Megalagrion is a genus of damselflies in the family Coenagrionidae. It contains approximately 26 species, all of which are endemic to Hawaii. Larval Megalagrion live in widely diverse habitats, including the expected streams and pools. Megalagrion also exploit some surprising habitats such as plant leaf axils, waterfall faces, and even damp fern litter far from water sources. M. oahuense is the only species of damselfly whose naiad is terrestrial, living in damp fern litter until metamorphosis. Many species of Megalagrion are in danger due to habitat loss and predation by non-native fish. 

Megalagrion koelense (Blackburn, 1884) is endemic to the Hawaiian Islands, it is known from Oahu, Molokai, Hawaii, Lanai and a historic record from Maui. It is widespread on the Hawaiin islands, though continuing deforestation will pose a problem to the species. This species breeds in leaf pockets of water (phytotelmata) of native plants (Astelia menziesiana and Freycinetia arborea). There are conservation measures in place, including monitoring the population size and trend of the species. Whilst research into the biology of Megalagrion koelense is underway, further research is still needed as well as the restoration of its habitat.
