Description

Nectaring on Silene acaulis.

From Alberta Butterflies (Bird, Hilchie, et al): "The Alberta Fritillary is medium-sized with muted, diffuse markings. The black spots are smudged on both dorsal and ventral wing surfaces. Silver, white and yellow markings are lacking although some females have a gray dusting on the ventral surface... Eggs are laid on Dryas octopetala. Adults fly low over windswept ridges and in alpine tundra. Females are often encountered in protected swales below the tops of ridges. Males appear to hilltop on ridges, often seeking the highest or most prominent part of the ridge. Adults will nectar at plants such as Moss Campion (Silene acaulis) and mountain avens (Dryas spp.)... Resident of the high alpine tundra, frequenting barren windswept ridges usually above 2000m in the north and 2400m in southern Alberta."
