Adaptation in the eye and brain contributes to species divergence in visual perception in Heliconius butterflies

This study shows how visual system adaptation in Heliconius butterflies leads to species divergence in perception and behavior due to ecological pressures.

Weighting of sensory cues reflect changing patterns of visual investment during ecological divergence in Heliconius butterflies.

The paper shows that Heliconius butterflies with greater visual neural investment preferentially use visual cues over olfactory cues in conflicting sensory environments.
