Zebra Blue closely resembles in both sexes on the upperside Common Tiger Blue, but the character and disposition of the markings on the underside are completely different. Male Upperside: dark violet with, in certain lights, a rich blue suffusion. Fore wing: no discocellular black spot so conspicuous in T. theophrastus; terminal margin with a narrow edging of fuscous black, widest at the apex, gradually decreasing to the tornus, followed by an inconspicuous anticiliary jet-black line. Hind wing : costal margin slightly but broadly shaded with fuscous, which is continued as a slender anticiliary black line to the tornus. Underside: white. Fore wing: with the following brownish-black markings:—an irregular edging along the costa to near the apex from which extends downwards a subbasal band, broadened across the cell and below it; an irregular band that extends along the discocellulars and below them to interspace 1 where it ends in a point; an upper discal curved band of more even width but dislocated below vein 4, the lower portion of it shifted inwards forms a large quadrate spot in interspace 3, below vein 3 the band is continued downwards by two small inconspicuous spots, beyond this is a very short acutely-pointed comma-shaped mark; a very regular evenly curved complete transverse lunular line, a transverse series of subterminal spots and an anticiliary slender line.

Larva is ale greenish yellow above, sides lilacine, a narrow brownish median line, followed by eight diagonal short streaks and six brownish-red spots. Before pupating the colouring gets much more diffused. Feeds among the flower-buds of Plumbago. Pupa is dull yellowish profusely mottled with brown spots.
