Appias lalage, the spot puffin,[1][2] is a small butterfly of the family Pieridae, that is, the yellows and whites, which is found in India, Indochina and Hainan.

Hindwing greyish-white, the basal area sometimes very faintly flashed with pale yellow; a prominently black outer-marginal band and connected submarginal zigzag fascia, the latter becoming broadly continuous and more or less confluent posteriorly.

Forewing with duller black markings similar to upperside, except that the apex is broadly pale greyish ochreous-yellow or glossy grey, with the sub-apical spots slightly indicated; the base of cell and costa being pale yellow, Hindwing paler yellow than in male, or greyish-white and slightly glossy, the yellow being more clearly defined along the vein borders and extreme outer margin, with slightly apparent dusky-scaled submarginal and medial zigzag fascia, and discocellular black dot, as in the male, the outer marginal interspaces being whitish and somewhat glossy.

Body greyish-white; front and abdomen above dark grey; antennae black above, white beneath in the male; anal tufts blackish; intromittent organ sometimes exserted.

Hindwing with the black outer-marginal band less intense than in the wet form, more macular, its connected submarginal zigzag fascia less defined and becomes obsolescent posteriorly from the upper median.

Forewing with the base glossy, the black outer band somewhat narrower, and its discal portion more or less disconnected, its posterior end always terminating at the lower median; the discocellular spot smaller and always isolated.

Forewing with the black outer band less prominent than in wet form, also narrower and its course broken, the apical area being pale greyish-ochreous and slightly irrorated with brown scales, the discocellular spot isolated.

Hindwing pale brownish-ochreous, more or less slightly irrorated with brown scales, the submarginal and discal zigzag brownish-scaled fascia slightly-defined, the discocellular black dot distinct.

Forewing with the base glossy; the black outer band similar, its lower end terminating either at the lower median or with some scattered scales inwardly-disposed before the posterior angle; the discocellular spot either slightly extending along upper median, or broadly joined to the discal portion of the outer band, and inwardly along upper area of the cell.
