Note: Some taxonomists believe that this butterfly is a separate species from the chryxuswhich flies elsewhere in Canada. Oeneis calaishas been proposed as the latin name for the butterfly which flies here in Eastern Canada. This is the designation currently used in eButterfly. "Calais Arctic" and "Barrens Arctic" are two english common names that have been proposed for this new species. This new taxonomy is yet to be universally accepted.
