Common NamePink-edged Sulphur SeasonalityOne flight annually, peaking in early July to early August. IdentificationCan be confused with small specimens of the Giant Sulphur (C. gigantea), but interior has a smaller underside discal spot, and the overall shape of the forewings is more rounded than pointy. In the mountains where the Pink-edged occurs together with the Pelidne, the pink wing fringe of interior is more pronounced, and the under- and upper side is not strongly suffused with black scales as in Pelidne.

Immature stages of the western populations are not known, but in the east, eggs turn orange (greenish yellow) soon after being laid. Mature larvae are dark yellowish-green with a dark dorsal stripe and a white and red lateral stripe (Guppy & Shepard 2001). Larvae hibernate.
Conservation Not of concern. Diet Info The larva feeds on blueberry (Vaccinium spp.) (Layberry et al. 1998), but it has not been reared in Alberta. Range The Pink-edged Sulphur is a typical boreal species, occuring from the eastern seaboard west to BC south to Oregon and Montana. In the eastern US, it is found only in the northermost states (Opler 1999).
