Golden Hairstreak

Habrodais grunus, the golden hairstreak, is a butterfly in the family Lycaenidae. It is found in North America in southern Arizona, Oregon, California, Washington, Idaho, and Mexico. The habitat consists of oak woodland, canyons and mountain ridges.

The wingspan is 25–32 mm. Adults have a golden-brown coloration on their body, and have a short tail. Adults are on wing from June to September in one generation per year. Adults are primarily crepuscular, being most active in the early morning and evening, while resting in shaded areas for the remainder of the day. They feed on moisture from various sources and possibly also feed on aphid honeydew or other exudates. They spend the majority of their time above in the trees, only descending for nectar.
