Sensory weighting reflects changing patterns of visual investment during ecological divergence in Heliconius butterflies
<p>Integrating information across sensory modalities enables animals to orchestrate a wide range of complex behaviours. The relative importance placed on one sensory modality over another reflects the reliability of cues in a particular environment and corresponding differences in neural investment. As populations diverge across environmental gradients, the reliability of sensory cues may shift, favouring divergence in neural investment and sensory weighting. During their divergence across closed-forest and forest-edge habitats, <em>Heliconius </em>butterflies <em>H. cydno</em> and <em>H. melpomene </em>evolved distinct brain morphologies, with the former<em> </em>investing more in vision. Molecular and anatomical data suggest selection drove these changes, but their behavioural effects remain uncertain. We hypothesised that divergent investment in neuropils may alter sensory weighting during behavioural tasks. To address this, we trained individuals in an associative learning experiment using multimodal colour and odour cues. When positively rewarded stimuli were presented in conflict pairing positively trained colour with negatively trained odour, and vice-versa, <em>H. cydno</em> prioritised visual cues more strongly than <em>H. melpomene</em>. Hence, differences in sensory weighting may evolve early during divergence and are predicted by patterns of neural investment. These findings, alongside other examples, imply that differences in sensory weighting stem from sensory investment as adaptations to local sensory environments.</p>
Shifting balances in the weighting of sensory modalities are predicted by divergence in brain morphology in incipient species of Heliconius butterflies
<p>Integrating and weighting sensory perception across modalities is crucial to how animals adapt to their environment. Divergence in brain structure is often in sensory processing regions, suggesting that investment reflects ecological needs. Here, we use two parapatric closely related species, <em>Heliconius erato cyrbia</em> and <em>Heliconius himera</em>, to test the hypothesis that divergence in sensory brain regions affects foraging decisions. These butterflies are isolated across an ecological gradient, which is linked to differences in brain morphology, with <em>H. e. cyrbia </em>investing more in visual centres and <em>H. himera</em> investing in olfactory centres. Here, we demonstrate that these two species vary in how they associate visual and olfactory cues with positive food rewards. We found that when individuals were trained on paired olfactory and visual stimuli, then presented with these stimuli in conflict, they showed distinct behavioural responses. <em>Heliconius himera</em> was more likely to favour positive olfactory cues than <em>H. e. cyrbia</em>, which favoured visual cues regardless of the paired stimulus. This suggests that these species have diverged in the emphasis placed on these different sensory domains during foraging, consistent with observed differences in brain morphology. This result strengthens evidence that speciation initiated by local adaptation is partly facilitated by changes in the neural basis of key behavioural functions.</p>
Social learning data in a foraging setting for Heliconius erato
<p><span>Insects may acquire social information by active communication and through inadvertent social cues. In a foraging setting, the latter may indicate the presence and quality of resources. Although social learning in foraging contexts is prevalent in eusocial species, this behaviour has been hypothesised to also exist between conspecifics in non-social species with sophisticated behaviours, including </span><span><em>Heliconius</em> </span><span>butterflies</span><span>. </span><span><em>Heliconius</em> </span><span>are the</span><span> only butterfly genus with active pollen feeding, a dietary innovation </span><span>associated with a specialised, spatially faithful foraging behaviour known as trap-lining. Long-standing hypotheses suggest that <em>Heliconius</em> may acquire trap-line information by following experienced individuals. Indeed, <em>Heliconius</em></span> <span>often aggregate in social roosts, which could act as 'information centres', and present conspecific following behaviour, enhancing opportunities for social learning. Here, we provide a direct test of social learning ability in <em>Heliconius</em> using an associative learning task in which naïve individuals completed a colour preference test in the presence of demonstrators trained to feed randomly or with a strong colour preference. We found no evidence that </span><span><em>Heliconius</em> <em>erato</em></span><span>, which roost socially, used social information in this task</span><span>. Combined with existing field studies our results add to data which contradict the hypothesised role of social learning in <em>Heliconius</em> foraging behaviour.</span></p>
Selection drives divergence of eye morphology in sympatric Heliconius butterflies
<p>When populations experience different sensory conditions, natural selection may favor sensory system divergence, affecting peripheral structures and/or downstream neural pathways. We characterized the outer eye morphology of sympatric <em>Heliconius</em> species from different forest types and their first-generation reciprocal hybrids to test for adaptive visual system divergence and hybrid disruption. In Panama, <em>Heliconius cydno </em>occurs in closed forests, whereas <em>Heliconius melpomene </em>resides at the forest edge. Among wild individuals, <em>H. cydno</em> has larger eyes than <em>H. melpomene</em>, and there are heritable, habitat-associated differences in the visual brain structures that exceed neutral divergence expectations. Notably, hybrids have intermediate neural phenotypes, suggesting disruption. To test for similar effects in the visual periphery, we reared both species and their hybrids in common garden conditions. We confirm that <em>H. cydno</em> has larger eyes and provide new evidence that this is driven by selection. Hybrid eye morphology is more <em>H. melpomene</em>-like despite body size being intermediate, contrasting with neural trait intermediacy. Overall, our results suggest that eye morphology differences between <em>H. cydno</em> and <em>H. melpomene</em> are adaptive, and that hybrids may suffer fitness costs due to a mismatch between the peripheral visual structures and previously described neural traits that could affect visual performance.</p>
Mate preferences act independently on different elements of visual signals in Heliconius butterflies
<p>Mating cues are often comprised of several elements, which can act independently, or in concert to attract a suitable partner. Individual elements may also function in other contexts, such as predator defence or camouflage. In <em>Heliconius</em> butterflies, wing patterns comprise several individual colour pattern elements, which advertise the butterflies' toxicity to predators. These wing patterns are also mating cues and males predominantly court females that possess the same wing pattern as their own. However, it is not known whether male preference is based on the full wing pattern or only individual pattern elements. We compared preferences of male <em>H. erato lativitta</em> between female models with the full wing pattern and those with some pattern elements removed. We found no differences in preference between the full wing pattern model and a model with pattern elements removed, indicating that the complete composition of all elements is not essential to the mating signal. Wing pattern preferences also contribute to pre-mating isolation between two other Heliconius taxa, <em>H. erato cyrbia</em> and <em>H. himera</em>, therefore, we next compared preferences for the same models in these species. <em>H. erato cyrbia</em> and <em>H. himera</em> strongly differed in preferences for the models, potentially providing a mechanism for how pre-mating isolation acts between these species. These findings suggest that contrasting levels of selective constraint act on elements across the wing pattern.</p>

Supplemental data for: Parallel shifts in flight-height associated with altitude across incipient Heliconius species
<p class="MsoNormal"><span>Vertical gradients in microclimate, resource availability and interspecific interactions are thought to underly stratification patterns in tropical insect communities. However, only a few studies have explored the adaptive significance of vertical space use during the early stages of reproductive isolation. We analysed flight-height variation across speciation events in <em>Heliconius </em>butterflies representing parallel colonisations of high-altitude forest. We measured flight-height in wild <em>H. erato venu</em>s and <em>H. chestertonii</em>, parapatric lowland and mountain specialists respectively, and found that <em>H. chestertonii</em> consistently flies at a lower height. By comparing our data to previously published results for the ecologically equivalent <em>H. e. cyrbia</em> (lowland) and <em>H. himera </em>(high-altitude), we found that the species flying closest to the ground are those that recently colonised high-altitude forests. We show that these repeated trends largely result from shared patterns of ecological selection producing parallel trait-shifts in <em>H. himera </em>and <em>H. chestertonii</em>. Although our results imply a signature of local adaptation, we did not find an association between resource distribution and flight-height in <em>H. e. venus</em> and <em>H. chestertonii</em>. We discuss how this pattern may be explained by variation in forest structure and microclimate. Overall, our findings underscore the importance of behavioural adjustments during early divergence mediated by altitude-shifts.</span></p>

Data from: Female mate choice is a reproductive isolating barrier in Heliconius butterflies
In sexually reproducing organisms, speciation involves the evolution of reproductive isolating mechanisms that decrease gene flow. Premating reproductive isolation, often the result of mate choice, is a major obstacle to gene flow between species because it acts earlier in the life cycle than other isolating barriers. While female choice is often considered the default mode in animal species, research in the butterfly genus Heliconius, a frequent subject of speciation studies, has focused on male mate choice. We studied mate choice by H. cydno females by pairing them with either conspecific males or males of the closely related species H. pachinus. Significantly more intraspecific trials than interspecific trials resulted in mating. Because male courtship rates did not differ between the species when we excluded males that never courted, we attribute this difference to female choice. Females also performed more acceptance behaviours towards conspecific males. Premating isolation between these two species thus entails both male and female mate choice, and female choice may be an important factor in the origin of Heliconius species.
