Butterfly Mimicry (IMAGE) Advanced Science Research Center, GC/CUNY Caption Males and females in some populations of the common palmfly butterfly resemble each other and mimic crow butterflies, but females in other populations are orange and mimic tiger butterflies. Ruttenberg et al. demonstrate that orange females have evolved repeatedly in different parts of tropical and subtropical Asia, and locate a putative genetic "mimicry switch" that determines female color form.
