Wingspan - 40 - 52mm. These whites differ considerably between first and second broods. The first brood is normally more heavily marked and the females more so than the males. Most first brood females have dark veins on the upper-surfaces of their wings. The first brood males may also, but not as obviously. The corners of the fore-wings are dark and the male has one spot on the fore-wing, the female two. The undersides of the hind-wings have dark green outlining the veins.
