The top side of the Kallima butterfly’s wings are brightly colored, featuring vibrant bands of deep blue, black, and orange. But when this butterfly flaps its wings, the undersides reveal a sharp contrast—they are shades of dull brown that perfectly mimic a dead leaf, camouflaging the butterflies from predators. In research published in the journal Cell on August 1, scientists discover which gene is responsible for leaf mimicry in Kallima butterflies and discuss what it means for our understanding of their evolution.
