DISTRIBUTION:

Catocala maestosa, the Sad Underwing (wingspan: 78-98mm), flies from New York south to Florida, west to Texas and Oklahoma and north to Illinois, Indiana and Minnesota. Maesotsa is quite similar to, although usually larger than, vidua. Both have the dark arc from the costa, above the reniform spot, to the outer margin just below the apex. Maesotsa, however, lacks the dark bar, found on vidua, parallel to the inner margin. The reniform spot is brown and there is brown shading just outside the postmedial line. The hindwing fringe is white, narrow and heavily barred.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Catocala maestosa are usually on the wing from July to October.

In Mississippi this moth has been taken from April to November, probably as a single brood with a very haphazard emergence pattern. The Catocala maestosa caterpillar feeds on hickories, pecans and walnuts.

ECLOSION:

Adults eclose from pupae at soil surface.

SCENTING AND MATING:

Catocala maestosa 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.

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.
