The undersides of the wings are grayish-brown featuring a few black spots, slightly edged with white scaling. Caterpillar larvae are light green with jagged whitish stripes and a dark brown head.
Adults fly from late May to early July. Found in unforested Sagebrush/Bluebunch Wheatgrass habitat in the south Okanagan Valley between 600 and 1100 m elevation where Silky and Sulphur Lupine plants are present. May have a mutualistic relationship with certain ant species.
