| Abstract: | Pachyrhynchus sonani Kôno, 1930, a legally protected species in Taiwan, is endemic to Lanyu Island (Orchid Island) and Ludao Island (Green Island). Because of its unclear life history, the host and immature stages of this species in the wild have not so far been recorded. On Lanyu Island, we recently identified Barringtonia asiatica as a host plant of P. sonani, with several larvae feeding on its xylem. Herein, we describe its biology and the habitat surrounding the host plant. |
