The Asiatic Rice Borer (Chilo suppressalis) is a moth of the Crambidae family. It is a widespread species, known from India, China, eastern Asia, Japan, Taiwan, Malaysia to the Pacific.
The wingspan is 25 mm. Females are somewhat larger than the males. Adults have pale yellow forewings, each with one or more dark spots. The hindwings are white.
The larvae feed on Chaetochloa verticellata, Echinochloa crusgalli cruspavonis, Echinochloa stagnina, Eleusine indica, Panicum barbinode, Paspalum conjugatum and rice. They bore the stems of their host plant. The larvae are yellow, with five dim longitudinal lines. It can grow to a length of about 25 mm. It is a serious pest of rice and it is largely responsible for the great reduction in the rice growing acreage in Hawaii.
Pupation takes place in a stem of the food plant.
