Swallowtail Butterflies, Pale and Western Tiger

Описание: We saw these swallowtails on the same bush on July 4, 2010 at Hawkins Bar on the Trinity River in California. There are the pale swallowtail (Papilio eurymedon) and the western tiger swallowtail (Papilio rutulus). I made the identifications using common field guides -- please let me know of errors.
