The Scarlet Mormon Butterfly, also called the Scarlet Swallowtail, is native to the Philippines. Its wingspan can reach 140mm.
The male (above left) has a basically black topside with streaked hind wings like other male Mormons;  the female (above right) has a bright scarlet central panel, but black body.

The top of the white markings on the male's hind wings is at a diagonal rather than straight, unlike the Great Mormon's, leaving a black lozenge shape visible above.
A red eye-spot is also sometimes visible. The male is tail-less (a similar-looking male, but with tails, is the Ascalaphus Swallowtail).
