The Hawaiian Upland damselfly (Megalagrion hawaiiense) is endemic to the state. Hawaiians called dragonflies pinao and damselflies pinao ‘ula. I’ve never been sure what the difference between the two is but I have learned that, among other things, damselflies tend to be smaller, have eyes on the side of the head that are clearly separate, and can fold their wings behind them.
This one was on the Kaumana Trail off Saddle Road (officially the Daniel K. Inouye Highway) at an elevation just over 5,000 feet.
