Kallima inachus

Orange oakleaf butterfly Strategy: masquerade as a dead leaf, with variety built in. Wings open, it shows the bold upperside that earned its name. Wings closed, only the underside shows, in leaf browns and buffs with darkened veins like a dry leaf's. No two look quite alike, because the underside markings vary a lot between individuals, which makes it harder for birds to learn what to look for. At rest on a trunk or the forest floor it is close to impossible to pick out, and people usually notice one only after flushing it by accident. It ranges across tropical Asia, from India through Thailand and West Malaysia to China and Taiwan.
