A medium-size compact rusty-orange noctuid moth. Forewings reddish or rusty orange and hindwings pale yellow-orange. The forewings are crossed by paler antemedian and postmedian lines, and the median area between the two is mostly darker red-brown. The terminal area beyond the postmedian line is divided into a darker basal half and a lighter orange terminal half. The orbicular and reniform spots are large and prominent, lighter orange than the associated ground, and somewhat angular.
Poorly known. The adults are nocturnal and come to light. There is a single brood each year, with adults flying in summer.
A fairly common widespread moth; no concerns.
