Size
Forewing length 5 - 6 mm (2).
Identification
Information below summarized from (1)(2).
Adults - both sexes generally dark coppery-bronze, forewings with dark fringe, hindwings metallic purple:
Males typically have 3 to 6 cream-colored spots on fore wing...two equally spaced along leading edge, and one on hind edge...sometimes with 1 more near the apex, and 2 smaller dots on each wing edge near the base. The 3 spot form was illustrated in Fig. 5 of Walsingham. Males also have larger eyes (diameter about 3 times distance between eyes on top of head) and longer antennae ( > 3 times wing length);
Females can have 4 or fewer vague spots, the case of 2 spots is illustrated in Fig. 6 of Walsingham. They also have much smaller eyes and antenna about 1.5 times forewing length.
Individuals can vary, with both sexes often having a reduced number and/or size of wing spots from those described above.
Range
Southern Washington (Columbia River region), southward (though records lacking in Oregon) through foothills and interior valleys of cismontane California, below 2000' elevation.(1)
Habitat
Open meadows (2).
Season
Late March to June.
Food
Associated with owl's clover Orthocarpus, some species now in Castilleja (2).
