Catocala herodias, the Herodias
(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.

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

FLIGHT TIMES AND PREFERRED FOOD PLANTS:
Catocala herodias are usually on the wing from July to August.
The Catocala herodias caterpillar shows a preference for oaks, particularly scrub oak.
Adults eclose from pupae at soil surface.
SCENTING AND MATING:
Catocala herodias 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.
