Identification:
It is generally larger than the other whites in the Nordic region.
The extent and shape of the black forewing tip is the best way to separate the species. On LAWH the black continues further down the outer margin, than on the other whites, leaving the impression of a symmetrical boomerang spreading out from the apex corner. The black marking on the apex is dusted white in 1st brood; more intense black in 2nd. Second generation is generally larger.
Males show no black spots on the upper forewing, the female two. The underside is pale yellowish with an individual amount of dark scales scattered throughout - never concentrated as on Grønåret Kålsomerfugl (Pieris napi) [Green-veined White ~ Blanca Verdinervada ~Rapsfjäril] though. Both sexes show two black spots on the underside of the forewing.
