Distribution in the Major Ecoclimatic Regions

We present the distribution of Alberta Lepidoptera among the three major ecoclimatic regions in Alberta ( Ecoregions Working Group 1989): Mountain (M/m), Boreal (B/b), and Grassland (G/g), in that order. An uppercase letter indicates that the species inhabits the prevalent habitat type (s) in the region ; alpine, subalpine, or montane in the Mountain region ; boreal forest in the Boreal region ; or grasslands in the Grassland region. A lowercase letter is used for species with limited occurrence in that region. For example, a species that is known only from small patches of grassland within the Boreal region would be indicated by “b,” and a species known only from small forested patches within the Grassland region would be indicated by “g.” A dash indicates that the species does not normally occur in that region. Species found only in the foothills, largely a transitional region between the Mountain and Boreal ecoclimatic regions, are indicated by “m b.” Species found only in the parkland, largely a transitional region between the Boreal and Grassland ecoclimatic regions, are indicated by “b g.” We obtained this information from the references and collections cited in the sections on taxonomic information and/or sources of Alberta records for the species in question, as well as the authors’ personal unpublished data .
