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.

Mating preferences act independently on individual elements of visual signals in Heliconius butterflies

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.

Adaptive divergence in the eyes of Heliconius butterflies likely contributes to pre- and post mating isolation

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

Adaptive introgression of a visual preference gene

The paper shows two Heliconius butterfly species evolved similar visual mating preferences through hybridization, linking a gene to behavior.

Quantifying visual acuity in Heliconius butterflies

The paper measures visual acuity in Heliconius butterflies using behavioural and morphological methods, finding higher acuity in males and implications for predator-prey interactions.

Oviposition behaviour is not affected by ultraviolet light in a butterfly with sexually-dimorphic expression of a UV-sensitive opsin

The study tests if UV vision affects oviposition in Heliconius butterflies, finding no impact on oviposition attempts or egg numbers.
