General Description

The dusky, smudged brown and dull-orange appearance of this fritillary is shared with B. improba, which is much smaller (28 - 35 mm vs. 35 - 45 mm). The Astarte Fritillary (B. astarte) is also found in B. alberta's lofty habitat, but is brighter orange with a more well-marked hindwing underside. B. alberta also has shorter, thicker antennae than astarte.
