Arctic White Butterfly
|The Arctic White is very common in the Anchorage area, and add delight to many of our trails. This one was seen along the Byron Glacier Trail, in a wooded area, July 7, 2004. It is nectaring on rockcress, Arabis lyrata. Arctic Whites prefer woodlands and alpine tundra, ranging through Alaska, Yukon, and Northwest Territories. Adults nectar on a wide variety of flowers. Caterpillars feed on plants of the mustard family. They overwinter as pupa (chrysalis).|
