Family: Nymphalidae, Brush-footed Butterflies view all from this family

Dimensions 1 7/8-2 1/2" (48-64 mm).

Endangered Status The Oregon Silverspot, a subspecies of the Zerene Fritillary, is on the U.S. Endangered Species List. It is classified as threatened in California, Oregon, and Washington. This butterfly has declined as its salt-spray meadow habitat has been lost to development or overgrown by forest. In its natural state this habitat is maintained by periodic fires. Fire suppression practices have prevented these fires, allowing forests to encroach and overtake the meadows. Recovery plans call for maintaining critical habitat in the six localities where this butterfly is still found, and for introducing captive-bred individuals to help boost populations.

Habitat Shorelines & salt marshes, Meadows & fields.

Range California, Northwest.
