The wingspan is 12–25 mm. It is an extremely variable species. The larvae feed on a wide range of plants. Recorded food plants are "Acacia confusa", "Acacia farnesiana", "Acacia koa", "Acacia koaia", "Alectryon macrococcus", "Caesalpinia kavaiensis", "Dodonaea viscosa", "Inga edulis", "Litchi chinensis",
Acacia koa survives best in pasture when planted under koa. This is because koa trees reduce radiative cooling, preventing frost damage to ōhia lehua seedlings. Koa is the preferred host plant for the caterpillars of the green Hawaiian blue ("Udara blackburni"), which eat the flowers and fruits. Adults drink nectar from the flowers. Koa sap is eaten by the adult Kamehameha butterfly ("Vanessa tameamea"). The koa bug ("Coleotichus blackburniae") uses its rostrum to suck the contents out of koa seeds. Koa is vulnerable to infection by koa wilt. Acacia koa Acacia koa is a species of flowering tree in the pea family,
