Extract
The spiny caterpillars of this butterfly are known as defoliators of snowbrush, Ceanothus spp.; Essig says that during severe outbreaks they feed on other shrubs and on fruit trees and alfalfa. The following records of flights are of particular interest in that no reports of damage by the caterpillars were received during the season of 1945.
