Description
The broad dark HW submarginal band is parallel to the wing termen but the FW has a pale patch adjacent to the post median line which like Cnaphalocrocis patnalis and C. poeyalis is displaced proximally to the rear of the FW unlike C. medinalis. The FW costa has a series of dark brown marks like some other Cnaphalocrocis spp. such as C. poeyalis. Schulze has specimens under this name but there are two different morphotypes in his series from Sabah. Cnaphalocrocis trebiusalis? Schulze (2000) taxon #341a and C. mimica? taxon #341b.
Life History
The larvae is a leaf-roller on grasses (Poacea). Reported on Opismenus compositus in Western Samoa (Swezey, 1941; Comstock, 1966)
