This species ranges from central Alberta to southern Manitoba, south through the western halves of the Dakotas to northern Texas, and west to northern Arizona, Nevada, and in parts of Idaho, Montana, and Colorado. In Idaho, it occurs in the south central part of the state.
It occurs in prairies, sagebrush steppe, and open woodlands.
Caterpillar: Caterpillars feed on the leaves of grasses including blue grama grass (Boutelous gracilis).
Adult: Butterflies drink flower nectar.
Caterpillars construct shelters from leaves tied with silk. There are two generations of caterpillars each year through most of its range, with possibly several in the south and only one at high elevations. Adults generally fly from late April through September through most of its range, and from mid-June through July at high elevations. Occasionally adults may stray into Iowa and Minnesota. The overwintering stage is unreported.
Males perch generally on small hilltops to wait for receptive females. Females lay light green eggs singly on or near host plants
