DISTRIBUTION: The Catocala serena moth (wingspan: 55-60mm) flies in southern Ontario, New York, New Jersey, Connecticut, Pennsylvania, Illinois and at least as far west as eastern Wisconsin. The head and collar and abdomen are brown while the thorax is grey. The black marginal band of the lower wings is indented at the center, and the relatively narrow, deep yellow median band parallels this indentation. Basal hairs are brown.

The pm line does not have the elongated "teeth" typical of many other Catocala species. Both the am and pm lines are thin, black and distinct on an otherwise relatively even grey (with a slight tinge of green) ground colour.

The hindwing fringe is pale orange and is not checked.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Catocala serena flies as a single generation with moths on the wing from July to September. The Catocala serena caterpillar shows a preference for Carya ovata (shagbark hickory) and Juglans nigra (Black walnut).

Moths come in to lights and to bait.

ECLOSION:

Adults eclose from pupae formed under leaf litter.

SCENTING AND MATING:

Catocala serena females emit an airbourne pheromone and males use their antennae to track the scent plume.

EGGS, CATERPILLARS, COCOONS AND PUPAE: Eggs are deposited on tree bark in the fall and hatch the following spring. Mature larvae Image courtesy of

Listed below are primary food plant(s) and alternate food plants. It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive, although some species seem very host specific. Experimenting with closely related foodplants is worthwhile.
