The CHOCOLATE PANSY Butterfly, Junonia iphita, above, also called the Chocolate Soldier, is native to the Indian subcontinent and SE Asia. The similar BROWN PANSY Butterfly, Junonia hedonia, from Asia-Pacific, also confusingly referred to as the Chocolate Soldier as well as the Brown Argus and even the Chocolate Pansy, is brighter and has a row of red spots on each wing.
The Chocolate Pansy comes in a range of shades including a reddish dark brown, "milk chocolate" and dark plain-chocolate brown, although the brown is never "plain" but has distinct patterns.
Another "milk" Chocolate Pansy.
From the underside, the male, above left, doesn't have the pale marks of the female, above right.
