Rhynchophorus bilineatus, common name Black Palm Weevil, is a species of beetles belonging to the family Curculionidae.

After hatching, the weevil larvae excavate tunnels in the trunk and feed on the tissues, frequently leading to the death the host plants.

Reports of Rhynchophorus ferrugineus from these areas are likely to be misidentified specimens of bilineatus.
