This species ranges from central Alaska south and east to Manitoba and Ontario, and throughout northeastern Canada. It also extends through British Columbia to northern Washington, central Idaho, and western Montana. Isolated populations occur in the Rockies, Great Lakes, and Appalachians.
The preferred habitat varies across its Range: mountainous or subarctic coniferous forests in the west and north, scrubby oak woodlands in the Great Lakes, and heath or pine barrens in the east.
Caterpillar: Caterpillars feed on members of the rose family (Rosaceae), such as cinquefoils (Potentilla spp.), wild strawberry (Fragaria virginiana), and blackberry (Rubus chamaemorus).
Adult: Butterflies drink flower nectar, often from yellow flowers.
There is one generation of caterpillars each summer. Caterpillars construct feeding shelters from leaves tied with silk. While the overwintering stage is not verified, it is believed that in some parts of its range (primarily the far north), individuals require two years to fully develop. Adults generally fly from May to August.
Males actively patrol and may occasionally perch to wait for receptive females. Females lay eggs singly on the leaves of host plants.
|Idaho Status:||Unprotected nongame species.|
populations are widespread, abundant, and secure.However, the subspecies P. centaureae wyandot in the east may be declining.
