The Mountain Fritillary is strictly a northern species with a rather narrow latitude range, all around the Pole, with an isolated population (ssp halli ) flying in Wyoming. This one was up on Eagle Summit, Alaska, on June 21, 2004. They live on tundra and alpine meadows. Caterpillars feed on bistorts, alpine smartweed, and maybe some violets. Adults nectar on a variety of alpine flowers. This species can take two years to complete its life cycle, making it one of the longest lived butterflies.
