Epipactis gigantea

Known as the Stream Orchid for its propensity for wetter areas and also as the Chatterbox for its moveable lip which "chatters" up and down in the slightest breeze, Epipactis gigantea is one of our more colorful native orchids. It is fairly rare in Washington but can be quite common in some areas. This was photographed in southern Oregon and a close look will show a small bee which spent a great deal of time working its way under the anther cap of the upper flower and which finally carried away the pollinia.
