The caterpillars of the species live in underground tunnels where they feed on the sap from the roots of the witchetty bush (Acacia kempeana) and the small cooba (Acacia ligulata). The caterpillar grows to a length of about 7 cm, and pupates underground inside its tunnel.

The adult moth is large (it has a wingspan of about 16 cm), with a fine mottled grey pattern and rusty red base on its wings. The moth has degenerate mouthparts, and is unable to feed itself, relying solely on nourishment obtained during its larval phase.
