DISTRIBUTION:

The Catocala hippolyta moth (wingspan: males: 72-76mm; females: probably larger) flies in California.

There is a white border just inside the subterminal line. The post medial line lacks any outward jagged projections, being more uniformly zig-zag except for an inward projecting "tooth" near the anal angle.

The inner black band on the scarlet hindwing is very narrow, tapering to a curved point, terminating well before the inner margin. The fringe is white and continuous from the apex to the anal angle.

Catocala hippolyta, Catocala nevadensis and Catocala pura may all be synonymous with Catocala semirelicta.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Catocala hippolyta flies as a single generation with moths on the wing from late June to very early October, with most moths done flying by the end of August.

Catocala hippolyta larvae probably feed on poplar as that is where above males were resting when captured. They are extremely well camouflaged at rest when hindwings are covered.

ECLOSION:

Adults eclose from pupae formed under leaf litter.

SCENTING AND MATING:

Catocala hippolyta females emit an airbourne pheromone and males use their antennae to track the scent plume. This is a sexually dimorphic species.

How many C. hippolyta can you find on the poplar trunk?? Keep looking!

EGGS, CATERPILLARS, COCOONS AND PUPAE:

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

Mature larvae probably feed at night, and they may hide in leaf litter during the day near the base of the tree.

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.
