The Pale Swallowtail or Pallid Swallowtail (Papilio eurymedon) is a relatively common swallowtail butterfly found throughout much of the western United States. It is found on the Pacific coast from northern Baja California to southernmost British Columbia and inland to New Mexico and the Black Hills of South Dakota. It is present from the coast to western Montana and Wyoming to northern New Mexico. It is absent from most of Nevada and western Utah. It prefers open woodlands and forest clearings, especially near permanent bodies of water such as ponds, but also urban parks and occasionally is seen in suburban areas.
