The California Sister
Butterfly 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 California Sister Butterfly adults will eat rotting
fruit and occasionally nectar. The Coast Live Oak, Quercus
agrifolia is a host species for the California Sister Butterfly, 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 for Oak Moths.
