The forest butterfly Common Archduke, Lexias pardalis, is a large (wing span 70-90 mm) fast-flying butterfly frequently encountered in forested areas of Singapore. Soh Kam Yung stumbled upon a pair feeding on fallen fruits which were fermenting on the forest floor. He obtained a beautiful image that contrasted the morphological appearances of the dorsal surfaces of male and female. There is marked sexual dimorphism. The uninitiated observer would inevitably conclude that they are two different species.
The Common Archduke is one of the Archduke species farmed for sale to butterfly collectors.
