Pterobilin
Pterobilin is a blue bile pigment found in "Nessaea" spp., "Graphium agamemnon", "G. antiphates", "G. doson", and "G. sarpedon". It is one of only a few blue pigments found in any animal species, as most animals use iridescence to create blue coloration. Other blue pigments of animal origin include phorcabilin, used by other butterflies in "Graphium" and "Papilio" (specifically "P. phorcas" and "P. weiskei"), and sarpedobilin, which is used by "Graphium sarpedon".
