California Sister (Adelpha californica) Some references call it Adelpha bredowii. It is a medium to large size butterfly in the Nymphalidae family. Wing Span is 2.5-3 inches. Habitat is oak woodland. Larval food plants are Coast Live Oak and Canyon Oak. It has 2-3 flights, April-October. They are common in California, but can also be found in western Nevada and Oregon, as well as in northern Baja California. The upper surfaces of their wings are dark brown to black with wide cream white bands dissecting both wings and two orange patches near the tips of the forewings. The underside is variously colored with browns, blue, orange, and white. A. californica is unpalatable to predators.
