Figure 4 in A review of three species-level taxa of the Anthocharis sara complex (Lepidoptera: Pieridae: Pierinae: Anthocharidini)

Figure 4. Close up of fifth instar caterpillar color differences of A. sara, A. thoosa, and A. julia. Species-level differences are most noticeable 48 to 54 hours after having molted from fourth instar. Dark green larval pinacula of A. thoosa and A. julia begin to darken and grow soon thereafter giving these fifth instars a more overall dark green appearance to the naked eye (superficially similar to A. sara) approximately 24 hours prior to pre-pupation.
