Pterobilin also called biliverdin IXγ in the Fischer nomenclature,[2] is a blue bile pigment found in Nessaea spp.,[3] Graphium agamemnon, G. antiphates, G. doson, and G. sarpedon.[4] 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.[4]
