Thanks to Robert Nold for his ID of the anise swallowtail. Eastern tiger swallowtails and western tiger swallowtails are very similar to each other, but anise swallowtails are distinct. Here are photos from the excellent field guide, The Butterflies of Cascadia, by Robert Michael Pyle, published by the Seattle Audubon Society. Those living in the PNW will find it indispensable for the level of detail it provides about our butterflies, with excellent range maps, habitat and behavioral information, and photos of all life stages. PBS members, so accustomed to scrutinizing plants for minute differences, should consider acquiring a regional butterfly guide. The anise swallowtail photo has an integral caption. The more yellow butterfly is the western swallowtail.
