Kallima inachus (Nymphalidae) is commonly named Orange Oakleaf or Dead Leaf. Their forewings have a strongly falcate apex, and the tornus of the hindwings is extended to form a short tail. The resulting shape, together with the cryptic underside colouration creates a remarkable resemblance to a dead leaf, complete with a fake ‘midrib’. The disguise is particularly effective because there is considerable intra-specific variation in the underside markings, which makes it very difficult for insectivorous birds to form a ‘search image’ for the butterfly.
K. inachus is found in India, Myanmar, Laos, Thailand, West Malaysia, China and Taiwan.
