Pterorhodin is a pteridine pigment found in animals and plants.[1] It has been extracted in melanosomes of tree frogs, butterflies, and plants as a wine red pigment.[2][3] In lemur tree frogs, pterorhodin allows skin to reflect the sun's heat.[4][5] Pterorhodin gives pigment color to bristle worms[6] and is found in the iris of multiple bird species including the red-eyed vireo[7] and the common loon.[8]
