Common Peacock (Papilio bianor) is among the prettiest butterflies found in the foothills up to 2,100 meter in Himalayas.

Using the species as a model to investigate the iridescent colour evolution, phylogeography, and the evolution of swallowtail butterflies a chromosome scale genome has been sequenced, the final assembly being 421.52 Mb in size, with 15,375 protein-coding genes and 30 chromosomes (29 autosomes and 1 Z sex chromosome).
