The Coon's wings are dark brown above, paler in the female, and with a slight golden hue.  The underside is paler and marked with a few small and rather obscure ferruginous spots.  The butterfly is rather local in Singapore, most often observed at the Bukit Timah Nature Reserve.  The caterpillar is known to feed on a species of Araceae.  

Where it occurs, several individuals are often seen together.  The butterfly has a short skipping flight and does not fly far if not disturbed.  This unattractive plain brown coloured butterfly would probably go unnoticed by the casual observer.
