The Pink-edged Sulphur (Colias interior) is a widespread boreal species, occurring primarily north of this region. In Maryland, the species is only known from high elevations of the Allegheny Plateau in Garrett Co., where it favors bogs and heaths where its host plant grows. This species also occurs as a relict population at high elevations in the Dolly Sods region of West Virginia (Butterflies of Maryland: A Biological Summary and Checklist by Lynn Davidson & Richard Smith; Brock & Kaufman 2003; Allen 1997). It is ranked as S1 (highly state rare) in Maryland.


This species uses velvetleaf blueberry (Vaccinium myrtilloides) or other Vaccinium as a host plant.
