DISTRIBUTION:

Catocala nevadensis = semirelicta (forewing length 30mm) flies in Nevada and California and is a dark semirelicta without the dark bar parallel to and slightly above the forewing inner margin.

The reniform spot is brown; the subreniform spot is much lighter, almost white and the area immediately outside the subterminal line is very dark.

The hindwing inner black band of nevadensis = semirelicta is narrow and terminates well before the inner margin. See Catocala semirelicta for more complete distribution.

Beutenmüller, 1907, also described the form "montana".

Catocala hippolyta is now (2010) regarded as a subspecies of Catocala semirelicta, while Catocala nevadensis and Catocala pura are considered to be synonymous with Catocala semirelicta.

FLIGHT TIMES AND PREFERRED FOOD PLANTS: Catocala nevadensis = semirelicta are on the wing in September and October. Kelly M. Richers reported a specimen on October 6, 2000, at Pleasant Valley Dam Road along Rt 395, (elevation 4430') in Inyo County, California, at a uv trap (image right).

The Catocala nevadensis = semirelicta caterpillar feeds on poplars and willows.

ECLOSION:

Adults eclose from pupae at soil surface.

SCENTING AND MATING:

Catocala nevadensis = semirelicta 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.
