The California Sister
has flights in the late Spring and Summer months. The caterpillars
feed on oak leaves. They prefer the live oak species but will also
feed on the deciduous oaks as well. The adults will eat rotting
fruit and occasionally nectar. With the strong community support for
the health of the oak trees there should be a recognition that these trees
are a part of a larger ecosystem and should not be sprayed indiscriminately.
