DISTRIBUTION:

Catocala alabamae, the Alabama underwing, (wingspan: 30-40mm) flies from Maryland south to Florida, west to Texas and north to Missouri and Illinois.

Titania (wingspan: 20-35mm) has recently been reclassified as alabamae and seems to have a more northern range with specimens taken in Pennsylvania. Alabamae has heavier, darker markings on the forewings and hindwings.

The uniform greenish-grey forewing may have thin but dark (contrasting) medial lines or they may be nearly absent (titania); alabamae often displays a dash in the median/anal angle area, missing or nearly absent in titania. There is brown shading between the post medial line and the subterminal line.

Titania by Vernon A. Brou.

Vernon Brou writes, "Catocala alabamae can be almost non-distinguishable from charlottae. In some specimens here at my home in Louisiana, alabamae's forewings are silver. Closer to Florida and in Florida some populations have forewings that are nearly pastel green.

"Here in Louisiana, alabamae's forewings can be silver to blue-green. It is possible C. charlottae will be synonomized or made a subspecies of C. praeclara when the MONA Catocala fascicle finally is published."

The outer fringe of the hindwing is pale orange and heavily checked with black.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Catocala alabamae are usually on the wing from April-May (Texas) to June, July and August elsewhere.

The Catocala alabamae caterpillar shows a preference for hawthorns, wild crabapple and Chickasaw plum.

ECLOSION:

Adults eclose from pupae at soil surface.

SCENTING AND MATING:

Catocala alabamae 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/bush bark in the fall and hatch the following spring.

Larval Food Plants

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.
