The Scarlet Mormon. Papilionidae family. It is found in the Philippines, but has been recorded as a vagrant to southern Taiwan.
The species was named by Johann Friedrich von Eschscholtz after Nicholas Rumanzow, Chancellor of the Russian Empire. It has traditionally been regarded as a species of its own rather than a subspecies of Papilio deiphobus. The wingspan is 120–140 mm. The male strongly resembles the male Papilio ascalaphus, but lacks the tail at the bottom wing. In contrast, the female has distinct red markings on the wings.
The larvae feed on Citrus species.
