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]
