These handsome, medium-sized moths fly from late August to October in forest habitats, including higher elevation spruce-fir and mixed-conifer forests, lower elevation ponderosa pine forests, and quaking aspen forests. Caterpillars feed on various plants in the rose family, including serviceberry (Amelanchier alnifolia) and mountain ash (Sorbus scopulina), but may also munch on willows (Salix spp.) in riparian habitats. They are found throughout western North America, from British Columbia and central Alberta south to central California in the west and to Utah and Colorado in the Rocky Mountains.
