Identification:
Male unmistakable in the Nordic region with an orange patch covering the distal half of the upper forewing followed by a blackish tip bordered by a pearl-like white margin.
The female shows the same black tip to the forewing as the male including the pearl-border but lacks the orange patch. Instead it has a well-defined small black spot on the forewing toward the front edge without reaching this.
Both sexes show black 'paint-spray' on the upper wingbase and the body.
The underside of both sexes show a cryptic dusty-green and white pattern which in the region can only be confused with Grønbroget Kålsommerfugl (Pontia edusa) [Eastern Bath White ~ Grönfläckig Vitfjäril] but the greenish pattern is more 'exploded/splashed out' than on the latter species. Also, the latter shows a bigger and more edgy black spot on the forewing reaching toward the front edge.
The wings are more rounded than seen on comparable whites.
