Abstract: A combination of five characters supports the taxonomic arrangement of three species in the Anthocharis sara complex consisting of Anthocharis sara (Sara orange-tip), Anthocharis thoosa (southwestern orange-tip), and Anthocharis julia (Julia orange-tip). These five characters include adult phenotypes, fifth instar larval coloration, pupal cone curvature and color, number of pupal overwintering cycles, and interspecific contact zone behavior. This taxonomic treatment is generated from extensive life history studies from 11 western U.S. states through most of the sara complex distribution.
