Description
The only differentiating characteristic between the two species is the colouration of the antenna. In the Dark Archduke, the apical topside of the antennae is black, whilst they are orange in the Archduke (Lexias pardalis dirtena). Both species have the undersides of the antenna coloured orange.

The males and females of both species cannot be distinguished when in flight. The species, like its lookalike, exhibits sexual dimorphism where the female is dark brown with yellow spots on both wings whiles the males are black with greenish blue wing margins.

Habitat & Habits
This species looks and behaves exactly like The Archduke (Lexias pardalis dirteana). It is also attracted by rotting fruit and can be found feeding greedily on these fruits on the forest floor.
