Pale Swallowtail Post Earrings --Papilio eurymedon
This common black and white butterfly is sometimes mistaken for the Zebra Swallowtail of Eastern North America. However, it's size and coloration on closer examination really set it apart with hints of blue and red within the wing structures.
There is one spring/early summer flight in Oregon, where one can witness hundreds on male butterflies drinking water at mud puddles and springs in forest canyons. Larvae feed on a variety of trees, with Ceanothus preferred.
Two gorgeous real Pale Swallowtail wing sections, from one specimen for symmetry.
