This Caterpillar hides in the soil at the base of the foodplant by day, and climbs the plant to feed by night. It feeds on a wide variety of herbaceous plants:
and other crops and weeds. Its habit of feeding on crops makes it an agricultural pest.
As the caterpillars grow, the later instars become darker, until they end up dark brown. They grow to length of about 5 cms.
The pupa is enclosed in a cocoon under the soil.
The adult moths have a complex grey-brown pattern on the forewings. The hindwings are white. At rest the moth holds its wings like a tent over its body. The moth has a wingspan of about 4 cms.
The species is found on the Pacific islands and
as well as over most of Australia, including:
