This species has a conspicuous basal dash, an open subreniform spot, and longer teeth in the pmline as compared to

and thick, while the postmedial yellow band is proportionately wider than in most

It is expected that larvae prefer Quercus douglasii Hook. & Arn.
Catocala johnsoniana are usually on the wing from late May to early July.
Adults eclose from pupae in leaf litter at soil surface.
SCENTING AND MATING:
Catocala johnsoniana females
emit an airbourne pheromone and males use their antennae to track the
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.
