Male. This butterfly exhibits sexual dimorphism: male butterflies are coloured bright gold-red on the upper side of wing with a dark edge, while the females have broader orange wings with a dark design. The lower surfaces of the back wings are yellowish and have only a few black dots with characteristic white marks in the immediate vicinity of these. The caterpillars live from April until June feeding on sorrel and the butterflies fly between June and August. They then lay the eggs that hatch in April after the whole winter.
