Workers in Europe and Asia include material from northern Arctic Asia within B. alaskensis. This has generally been accepted, but is not proven.
Explanation of Names
In the past, this species has usually been considered to be part of the Eurasian species Boloria napaea. It is also very similar in appearance to Boloria pales, the European type species of the genus.
There is much debate as to species limits, and as to just how many species there are within the subgenus Boloria (to which this species belongs). Some would argue that there are only one or two species worldwide. Others divide it up into numerous regional species, with B. alaskensis being the American and north Arctic Asian representative. There are most likely (?) about four or five "real" biological species.
Arctic northwestern North America in Alaska, Yukon, N.W.Territories, & western Nunavut, but also extending southward in relictual Alpine colonies through the Canadian Rockies into British Columbia & Alberta, and isolated in the Wind River Range in Wyoming. Also arctic north Asia.
