Tufted jungleking, Thauria aliris Frühstorfer 1902, Sarawak / Borneo around 1100m ASL

Thauria aliris is a remarkable butterfly, with a 11 to 13cm wingspan. Like other members of the genus Thauria, the ventral wing surfaces are disruptively patterned and look like dead leaves, allowing the butterflies to blend into leaf litter on the forest floor. Between the gamut of light and shadow on the forest floor, is this butterfly almost invisible.
