The female of the scarlet mormon (Papilio rumanzovia) can vary a bit in apparance, but they are all very pretty butterflies with the red accents on a black base. This one is also a female of the same species: www.flickr.com/photos/tinyturtle/51966869231/
And the underside is also very attractive - like so: www.flickr.com/photos/tinyturtle/53653353393/
The male has red on the underside of the wings, but the dorsal side is significantly more subdued, like here: www.flickr.com/photos/tinyturtle/52698707189/
