Life Science Mimicry in Butterflies: The Muse, the Palette and the Artist
ByWIREs AuthorsPosted on September 28, 2017
A caterpillar prepares for its legendary transformation from a pupa into a colorful butterfly. Through this metamorphosis, a bag of developmental genetic tricks lays down bright color patterns that help the butterfly attract its mates and warn or fool its predators.
Few adaptations in nature are as striking and widely appreciated as the bright wing color patterns of butterflies. These color patterns have evolved to serve crucial functions, including predator avoidance through warning coloration and mimicry. Mimicry is the phenomenon of gaining protection from predation by resembling toxic prey species that experienced predators avoid. Mimicry in butterflies has been intensively studied for several decades, but now the rapidly expanding field of genetics of wing patterning has made butterflies emerging model organisms for developmental genetic research.
