This butterfly was seen on the Flattop Mountain trail in late April, 2003. They are abundant all over town and into these higher elevations this spring (2003). Their range includes much of North America. Although they reach their adult form in the summer, many will overwinter and awaken the following spring, with the return of the sun. Alaska experienced unusually warm temperatures this winter and spring, allowing large numbers to survive into this early spring. This specimen has the tattered look of an older individual.
here to see another specimen that I found a few
days later, along a trail in the city of Anchorage, with hindwings intact.
