Logania watsoniana, or Watson's mottle,[1][2] is a small but striking butterfly found in India that belongs to the lycaenids or blues (family Lycaenidae).

Female upperside: similar to that of the male, but differs as follows: Forewing: base outwardly to beyond the cell strongly suffused with bluish grey, only the upper apex of the white area with the ground colour distinctly showing through; apex and termen more broadly and more densely black.

Hindwing: entirely bluish grey, the costal margin broadly irrorated with dusky scales.

Underside: as in the male, but the costa, apex and termen broadly in the forewing, as well as the whole surface of the hindwing, mottled with brownish; the scaling of this colour forms irregular spots and patches especially on the hindwing, which has a blotched appearance compared with the same wing in the male.

The basal fuscous cloud extends into the medial white area in the forewing as in the male.
