The forewing is generally grey-brown with a greatly widened (near the costa only), white, subterminal line.
The outer black band of the hindwing is unbroken and the inner band forms a complete loop with considerable brown scaling along the inner margin.

"mellitula" Hulst has a blackish patch in the basal area from the costa to the inner margin;
"obliterata" Schwarz is the melanic form, with an almost completely black forewing;

Steve writes, "The Little Wife is one of the signature species of Jamaica Bay -- but this one was 11 days (seems to be a magic number, or times 2) earlier than the previous early date here. The Little Underwing was new for Jamaica Bay -- and I had 6 of them. Funny how that happens."

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Catocala minuta are usually on the wing from June to August.
The Catocala minuta caterpillar feeds on honey locust and water locust.

ECLOSION:

Adults eclose from pupae at soil surface.

SCENTING AND MATING:

Catocala minuta 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.
