DISTRIBUTION:

Catocala herodias, the Herodias Underwing, (wingspan: 55-65mm) flies from Massachussetts, Connecticut, New York to Virginia as Gerhard's Underwing, herodias gerhardi Barnes and Benjamin, and in Texas and Oklahoma as herodias herodias.

The forewing is grey and brown, generally lacking any trace of medial lines. Instead forewing veins are somewhat darkened in the median areas with white streaks from the post medial line to the outer fringe, running parallel to the inner margin. Catocala herodias gerhardi has a distinctive very light, almost white, border along the forewing costa. Catocala herodias gerhardi courtesy of James Reilly, Virginia.

The light border is missing in herodias herodias. The hindwings are reddish-orange with black bands and white fringe.

Both moths seem restricted to oak-pine barrens

SCENTING AND MATING:

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

Eggs are deposited on tree bark in the fall and hatch the following spring.

The list is not exhaustive, although some species seem very host specific. Experimenting with closely related foodplants is worthwhile.
