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

The paper examines how divergent warning coloration patterns influence mating behaviors in male and female Heliconius butterflies, finding that both sexes prefer conspecific coloration but only male coloration affects mating success.

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

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

The paper examines flight-height variation in Heliconius butterflies during speciation, finding parallel trait shifts linked to altitude and environmental selection.

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

This study investigates whether sexual conflict contributes to the diversification of warning patterns in Heliconius butterflies, finding that sexual conflict can assist pattern diversification but genetic architecture and sex-specific costs also play roles.

This study shows that light conditions affect mating behaviors in Heliconius butterflies, with differences in visual attraction contributing to low-level assortative mating.

This study shows that neural divergence and hybrid disruption occur in Heliconius butterflies due to environmental transitions, contributing to reproductive isolation.

The paper investigates the genetic architecture of male pheromone compound production in Heliconius butterflies, finding significant QTL clustering on specific chromosomes.

The paper identifies genes linked to visual mate preference divergence in Heliconius butterflies through QTL analysis and gene expression studies in neural tissues.

This study identifies a major genetic locus controlling octadecanal production in Heliconius melpomene, a biologically active pheromone component involved in mate choice.

The paper examines chemical profile divergence in Heliconius butterflies, finding strong interspecific differences and some intraspecific variation, with implications for species recognition.

The paper identifies a novel terpene synthase in Heliconius melpomene that synthesizes (E)-β-ocimene, an anti-aphrodisiac pheromone, showing it evolved independently from plant and other insect TPSs.

This study identifies three large-effect QTLs underlying divergent male preference behavior in Heliconius butterflies, linking them to color pattern genes and suggesting modular evolution of assortative mating traits.

The study investigates how larval and adult diets affect pheromone composition in male Heliconius melpomene, finding no effect of adult diet but variation due to larval host plants.

This study examines reproductive isolation in Heliconius butterflies, finding that increased divergence leads to stronger barriers, with wing pattern being important early on but not essential for speciation.
