Sabera caesina, the white-clubbed swift or black and white swift, is a butterfly of the Hesperiidae family. It is found in Australia in Queensland, Papua New Guinea, and in Indonesia in the Aru Islands and Papua. The wingspan is about 30 mm. The larvae of subspecies S. c. albifascia feed on Archontophoenix alexandrae, Normanbya normanbyi and Calamus caryotoides. During the day, it lives in a shelter made from a cut and folded leaf of the host plant. S. c. barina probably feeds on Licula or Calamus species.
