Formerly considered the same species as the Veined White, the West Virginia White is in fact a completely distinct butterfly, occupying moister, shadier, generally more southern habitats. From Maryland to North Carolina in the Appalachians it is rather widespread and common. But populations farther north are becoming fewer and sparser as the butterfly's native woodlands are altered. In Ontario, the West Virginia White is an Endangered Species
