This species has a small range which runs from the Wasatch Mountains of Utah straight north through the Rocky Mountians on the border of Idaho and Wyoming and into southern Montana.
It is most often found in moist habitats, including meadows, forest edges, and clearings.
Caterpillars feed on various species of violets (Viola spp.).
Adult: Butterflies are known to obtain flower nectar from asters (Aster spp.) and yellow colored flowers of the sunflower family (Asteraceae).
There is one generation of caterpillars each summer. Caterpillars overwinter in a physiological state called diapause. Adults generally fly from mid-June to early August.
Males find receptive females by actively patrolling meadows. The locations chosen by females for laying their eggs have not been reported.
