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

This study shows that visual acuity improves during early adulthood in Heliconius butterflies through neural development, despite no change in eye structure, and that this maturation coincides with reproductive behaviors and is disrupted in hybrids.

The paper examines sex-specific foraging strategies and sensory traits in Heliconius himera butterflies, finding females carry more pollen but both sexes forage on similar plants, with males having larger eyes and females larger mushroom bodies.

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

The paper tests whether male Heliconius butterflies prefer full wing patterns or individual elements, finding no preference difference when elements are removed, suggesting independent function of pattern elements in mating and speciation.

The paper examines eye morphology divergence between Heliconius species and their hybrids, finding adaptive differences and visual system disruption in hybrids.
