Butterflies of Alaska



Field Crescent
Phyciodes pratensis


The Field Crescent is fairly widespread through North America's western states and provinces. They live in a variety of habitats from mountains to fields, often near rivers or streams. This one was found by Hick's Creek in the Mat-Su Valley, Alaska. Caterpillars feed on a variety of asters, and overwinter, partially grown.
