Our 2023 fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. Your support is vital to the project. Please make a recurring or one-time donation to sustain this valuable source of information. Thank you!
Observation notes: Slammed on the brakes but this butterfly never settled. I got a few poor flight shots - my apologies. Dorsal side, with more extensive yellow, resembled Giant Swallowtail in flight. Photos reveal abdomen and ventral side more consistent with Black Swallowtail (orange spots and iridescent blue highlights). Could this be a rudkini subspecies?

Coordinator notes: Bob, your hard-won pics are just helpful enough to call this Old World Swallowtail. Yellow shoulders, Rows of yellow dots on the abdomen. VHW postmedian yellow band has only a little orange. Red eyespot on the VHW is just visible enough to show black pupil meets yellow "iris" and the inner wing edge. Good work!
