Species guidance

Identification: A white moth with black lines and zigzag patterns on forewings. A diffuse black line from base to the outer margin of the wing. Hindwing orangish to pinkish red with black bands.

Similar Species: C. marmorata has a curved, diffuse black band on the forewing from the leading edge to the outer edge and the background in pale grey. Hindwing usually reddish-pink.

Habitat: A species of boreal affinity found in northern forests.

Host Plant: Poplars and willows, probably specifically on balsam poplar (Ferge, pers.comm.).

State Distribution: Door, Marinette, Florence and Forest of the northeast, and Douglas in the northwest.

Global Distribution: Nova Scotia and Maine across Canada and into northern Michigan and Wisconsin.

Phenology: Adults July-September.

Life and Natural History: After larval development, the caterpillars will cease feeding and shorten in preparation for pupation. Underwing moths overwinter as eggs. Larvae hide in debris during the day and feed during the night on the succulent parts of the trees. Most Noctuids are nocturnal and females attract males by the release of pheromones.

Survey Guidelines: Attracted to artificial light. Many Catocala species are attracted by "sugaring" along forest paths and edges (Rings, et al. 1992).
