are hard to spot. The subterminal line is inwardly lined with light
scales. Hindwing fringe is white, checked halfway to the outer edge
with black, with a black line on each wing vein extending through
the fringe. There is some orange bleeding at the apex. The black
median line terminates well before the inner margin.

The Catocala californica caterpillar shows a preference for
Juglans nigra (questionable) and Salix.
Pete Smytheman indicates he has reared larvae on willow and aspen, but they refused walnut.
Adults eclose from pupae at soil surface.

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.
