Philus antennatus (Gyllenhal) (Coleoptera: Vesperidae) is a notorious pest in the Matou wentan,Citrus grandis, Osbeck cv. Matou Wentan, and Matou peiyu orchards of Madou Township, Tainan County, southwestern Taiwan. The larvae of P. antennatus develop in soil, damage the roots of Matou wentan and Matou peiyu, and cause defoliation of the tree and eventual death. The morphology of each stage of P. antennatus is illustrated and described in this article. Surveyed in May, 2004, the emergence of adult of P. antennatus peaked at May 27, on which night we caught 1690 adults of P. antennatus. The fecundity was 509.3 ± 118.2 eggs/female.
