Physical Description of Adult Butterfly:
The Malay Baron exhibits sexual dimorphism. On the upperside, the male is dark brown. In the typical form -f. monina, the distal border on the hindwing is blue and bears a series of small black sagittate markings. In form -f. decorata, the upperside is paler brown with more clearly defined post-discal fasciae and the hindwing has a coppery green border. In form -f. gardineri, the upperside is dark brown with obscure fasciae and the hindwing border is not additionally coloured. At times, males could appear bearing appearances integrating the above 3 forms. The female resembles the female Tanaecia iapis (Horsfield's Baron) with the exception of the presence of a dark zigzagged line in the white post-discal band on the forewing.
