The sitka locations are a huge distribution extension from previously reported zerene populations. For purposes of scale, note that the linear distance from the south end of Vancouver Island to Haines, Alaska is about 1460 km. Road access to the Coast Mountains of British Columbia and Alaska is limited and the region is not known as a good place to look for butterflies. So I don't expect to see significant new information on the distribution of coastal/near coastal zerene populations in this region during the remainder of my life. Folks with acrophobia issues should be cautious in exploring roads in the Coast Mtns. One year long ago I made the mistake of driving to Bella Coola, BC and due to a section of cliff -hugging road, I came very close to suffering both a heart attack and soiling my diaper -----
