Baltia butleri, the Butler's dwarf, is a small butterfly of the family Pieridae, that is, the yellows and whites.

Forewing has the black markings also more or less similar but altogether smaller and narrower, the terminal series of spots reduced to three or four.

Hindwing: ground colour pinkish ochraceous, the veins conspicuously white; all of them, except a small portion in the middle of the discocellulars, bordered, in the manner similar to the veins at the apex of the forewing, with broad lines of black scales on each side.

On the hindwing the discocellulars are prominently marked with an upper and a lower black spot, and the discal macular band is more conspicuous than in the female B. shawi.

It differs from the typical form on the upperside, in the male by the restriction and narrowness of the black markings, in the female by the ground colour which is tinged with greenish yellow.
