Habrodais grunus, the golden hairstreak, is a butterfly in the family Lycaenidae. It is found in North America in southern Arizona, Oregon, California 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[3]. They feed on moisture from various sources and possibly also feed on aphid honeydew or other exudates.
The larvae feed on the young leaves of Chrysolepis chrysophylla, Quercus chrysolepis, Quercus vaccinifolia and Lithocarpus densiflorus.[4] The caterpillars are blue-green in color on their body, and have silver hairs. The caterpillars will mature to their adult stage in the span of approximately 2 weeks.[5]
