This butterfly appears in some literature as Clossiana tritonia astarte.

EXTREMELY RARE and HARD TO GET!
Found only 7000 ft above sea level at only where there is scree slopes and cliff edges. Very risky to collect.

This species is the largest (wingspan: 41 to 50 mm) of the lesser fritillaries. The tips of the wings are more pointed than in the Alberta Fritillary. The upperside is orange with black markings. On the hindwing underside there is an orange band along the margin marked by black and white spots. The basal part of the wings has a reddish ground colour crossed by a wide whitish or buff band.

Subspecies: According to some authors, there are two subspecies in Canada. The nominate subspecies is found from northern British Columbia (57° N) southward; subspecies distincta, which is more dusky with a more orange, less contrasting, hindwing underside, occurs in Alaska, Yukon, and adjacent northwestern BC, and western Northwest Territories.

Range: This is a species of northwestern North America and northeastern Siberia. In Canada, it flies in the high mountains of western Alberta and central British Columbia north to the British Mountains in Yukon, and in the Northwest Territories in the Richardson and Mackenzie Mountains close to the Yukon border. Its range extends into the U.S. in Montana and Washington.
