a copper color. At the sixth and final instar, the head remains copper and the body and develop a dorsal hump. The total time for this larval development is four to six weeks and the final body length ranges from .

This may vary in other parts of the range. Larvae can be found feeding on plant leaves during the night. They are typically located on the underside of the leaves of the host plant close to the ground. Larvae are gregarious feeders in their initial stages. In the fourth instar, the larvae may disperse to the other areas of the original host plant and may migrate to other host plants. When forming into pupae, the larvae will burrow into the soil where they will remain until they emerge as adults. Pupae The pupae are brown and glossy. Pupae can develop once or twice during the year, with pupation typically taking place over winter. Pupae develop within cocoons that are found in the soil. The pupae are generally 20 mm long. The pupae can be found in the ground anywhere from 2–10 mm deep into the soil. Adults Adult moths emerge from the pupae in soil during the months of May and June. Their appearance is similar to many moths within the same family; they are gray, black, green, or brown with delicate patterning of lines and spots across the entire adult body. The forewings tend to be darker than the hindwings in color. Characteristic markings of the species include a kidney shaped spot enclosed in a white border on the forewing of the adult. There is also a thin white border that goes around the entirety of the forewing. The wingspan
