Graphium leonidas (Veined Swordtail or Veined Swallowtail) (B00139, GH00083)
This is one of the restless butterflies in Shai Hills Reserve. I have only this unsatisfactory but clear picture. For a record here.
Since it's such a fast flyer, many resources doubt its mimetic relationship with Tirumala species, as described in Larsen book.
