The length of the forewings is 64–80 mm. Adults are dark brown with bluish or greenish hues. There is a whitish-cream transverse band and an apical whitish spotted band on the forewing. The hindwings are dark brown with a whitish-cream band. The spots are red or reddish with the middle spots larger in size.

The larvae feed on Saccharum officinarum, Musa, Heliconia and Ichnosiphon species. It is considered a pest species. Young larvae make a small cavity and then tunnel into the heart of the cane of the host plant. They tunnel upwards and downwards, and create a shelter in the rootstock where they rest. Pupation takes place in the rootstock or at the base of the cane.[1]
