Adult butterflies feed on tree sap and nectar from sweet everlasting (Gnaphalium) as well as other flowers.^[3] Caterpillars feed on shrub leaves including currant (Ribes), western azalea (Rhododendron occidentale) and mock azalea (Rhododendron menziesii).

The species survives the winter in the adult stage in diapause and mate and lay eggs in the spring. Butterflies emerge from their chrysalids in midsummer.
