The caterpillars of the moth are known as "witchetty grubs", and were used as food by the indigenous Australians. The caterpillar is white and cylindrical with a brown head, and looks like a fat grub. The caterpillar feeds underground and pupates inside its tunnel. The adult moth is patterned shades of brown and grey. The forewings are brown with pale markings forming a band along the centre of the wing. The hindwings are light brown. Both pairs of wings have a reddish brown tinge at the base.
