Identification
Distinguished from related tiger moths by its Rocky Mountain distribution and association with subalpine . The small forewing length (16–17 mm) and mid-summer period help separate it from larger or earlier-flying . Former placement in Neoarctia may cause confusion with older literature.
Appearance
have forewings measuring 16–17 mm in length. As a member of the tiger moth Arctiinae, it likely displays the characteristic patterning of the group, though specific coloration details are not well documented in available sources.
Habitat
Open forests, subalpine meadows, and parklands in montane regions. Occupies elevations characteristic of the Rocky Mountain cordillera.
Distribution
Recorded from the Rocky Mountains of Alberta, British Columbia, and southern Montana in western North America.
Seasonality
are active from mid-July to mid-August.
