Male (paralyzed?) - Howie Road Manion Corners, ON 22/06/2012
Female (White Form) - Gatineau Park, QC 22/07/2013
This familiar butterfly is probably the most common yellow butterfly in most of the Maritimes.
Like most other members of this subfamily, this species does not normally rest with its wings open. The individual pictured at top right was found paralyzed with its wings open. When viewed dorsally, its pale yellow colour is more easily distinguished from the orangish colour of the Orange Sulphur .
