is western black swallowtail. White spots on abdomen only occurs with a few black species so your observation is noted. Baird's Old World Swallowtail has white abdominal spots but dorsal wing spots are yellow rather than white. Subspecies pergamus of Indra as well as Anise Swallowtails do not have abdominal white spotting. White dorsal spotting of wings and abdominal white spots indicate Papilio polyxenes.

Thank you for your input Cliff Ivy. I looked at all the pics of p. indra and none show the spotted abdomen that my specimen does. Those spots would indicate P. polyxenes more closer but is there other indications that show otherwise?
Sincerely,
Rodney

Thanks for your input Nancy Kent, I was thinking p. polyxenes because of its markings.
