DISTRIBUTION:

Catocala micronympha, the Little Nymph Underwing, (wingspan: 35-50mm) flies from southern Ontario and Quebec (very rare) through New Hampshire and Connecticut and New Jersey to Florida, west to Texas and then north through Oklahoma, Kansas, Iowa, etc., to Wisconsin and Minnesota and then east to Michigan.

Moths come in to lights and to bait.

The forewings are extremely variable and there are several forms denoted with no basal dash in any of them:
"gisela" Meyer has a forewing that is mostly black;
"hero" H. Edwards has a median area that is mostly white;
"sargenti" Covell (very rare) has a hindwing that is all black.

The usual specimens have grey forewings shaded with green, brown, black and white tints. There is usually a darkened band passing from the costa through the reniform spot to the outer margin. The lower lobes of the pm line are quite distinct, especially in those specimens with light scaling in that area. Image courtesy of John Himmelman, Connecticut, July 24, 2003. The typical resting position for this moth is "head down".

Micronympha is also known as the "Little Bride" and as the "Tiny Nymph" Underwing.

Catocala micronympha from Maryland.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Catocala micronympha are usually on the wing from July to September.

In Florida, there may be a flight as early as late April.

The Catocala micronympha caterpillar shows a preference for oak species.

ECLOSION:

Adults eclose from pupae at soil surface.

SCENTING AND MATING:

Catocala micronympha 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.

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.
