This is perhaps one of the commonest larger-sized swallowtail in a forested area in Raub, readily recognisable by its white patch on its hidwings even in flight. It is a swift and strong flyer and can be readily observed visiting flowering patches in an open area or sandbanks by a stream later in the afternoon.
