Several species or groups of species of particular interest are described here.
One is the Koa bug, Coleotichus blackburniae. A good description is here: https://www.fws.gov/refuge/hakalau_forest/wildlife_and_habitat/koabug.html. The species is in the true bug family Scutelleridae. The site describes factors that have reduced the species abundance. Other basic information about the species is here: https://en.wikipedia.org/wiki/Coleotichus_blackburniae.
Another species is the Wekiu bug (Nysius wekiuicola), an endemic seed bug that is found at high elevations on Mauna Kea and with some very interesting habits. The Wikipedia page with basic information is here: https://en.wikipedia.org/wiki/Nysius_wekiuicola.
