Cepora nadina, the lesser gull,[1][2] is a small to medium-sized butterfly of the family Pieridae, that is, the yellows and whites.

Forewing: costal margin and apex very broadly suffused with greenish yellow and irrorated more or less densely with black scales, these latter form also diffuse subterminal patches on the white ground colour in interspaces 3 and 4; a preapical oblique short band bright yellow, its margins ill-defined; in interspaces 1 to 3 the black terminal markings on the upperside show through as a greyish-blue shade.

Underside: similar to that of the male, but the white area on the forewing more restricted and of a purplish tint, the dusky-black shading on the disc that borders the green on the apical area broader, and the greater portion of interspaces 1a and 1 also shaded with dusky purplish black.

Hindwing: darker than in the male, the veins more prominently bordered with black scaling, the posterior, discal, ill-defined, dark band or patch broader and more conspicuous.
