This species is quite variable. The white or brownish-white wings, the irregular brown cross-band on the forewing and the quite plain hindwing are all diagnostic. The central band varies in width and is sometimes split into two blotches (f. degenerata) or one small blotch close to the leading edge (f. costimaculata). The band can also vary between greyish brown to dark-brown, usually with some white.

Pupates in loose earth.
