occurs (regularly, as a native taxon) in multiple nations
Regularity: Regularly occurring
Type of Residency: Year-round
Global Range: (20,000-2,500,000 square km (about 8000-1,000,000 square miles)) Mountains of western North America, from Oregon south to California, east to the Great Plains. Somewhat local.
Catalog Number: USNM
Collection: Smithsonian Institution, National Museum of Natural History, Department of Entomology
Locality: Californie. Date:Unknown, California, United States
Comments: Usually below 8000 ft.; in moist areas, mountain meadows, clearings. Larval host is genus Ribes. Mostly a woodland species often in canyons.
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 81 to >300
10,000 to >1,000,000 individuals

Degree of Threat: D : Unthreatened throughout its range, communities may be threatened in minor portions of the range or degree of variation falls within natural variation
Global Protection: Many to very many (13 to >40) occurrences appropriately protected and managed

The average wingspan ranges from 30–35 mm. Each hindwing has a tail. The upper surface of the males is copper-brown with an iridescent purple sheen. The upperside of the females has an orange and dark brown pattern. The underside of both males and females is grey, with black spots on the forewings and a band of white crescents on the hindwings. Adults are on wing from May to August in one generation per year. They feed on flower nectar.
The larvae feed on the leaves of Ribes species. The species overwinters as an egg.
