Abstract: Abstract In many animals, mate choice is important for the maintenance of reproductive isolation between species. Traits important for mate choice and behavioral isolation are predicted to be under strong stabilizing selection within species; however,… read more here.

DOI: 10.1002/ece3.9286
Abstract: Abstract Identifying the relative importance of different mechanisms responsible for the emergence and maintenance of phenotypic diversity can be challenging, as multiple selective pressures and stochastic events are involved in these processes. Therefore, testing how… read more here.

DOI: 10.1093/molbev/msac067
Abstract: The evolution of color vision is often studied through the lens of receptor gain relative to an ancestor with fewer spectral classes of photoreceptor. For instance, in Heliconius butterflies a genus-specific UVRh opsin duplication led… read more here.

DOI: 10.1098/rsos.241097
Abstract: Spatial learning is vital in foraging ecology. Many hymenopteran insects are adept spatial foragers that rely on visual cues contained within broader wide-field scenes for central place foraging from a central nest. By contrast, for… read more here.

Exploitation of an ancestral pheromone biosynthetic pathway contributes to diversification in Heliconius butterflies

DOI: 10.1098/rspb.2022.0474
Abstract: During courtship, male butterflies of many species produce androconial secretions containing male sex pheromones (MSPs) that communicate species identity and affect female choice. MSPs are thus likely candidates as reproductive barriers, yet their role in… read more here.

Ultraviolet and yellow reflectance but not fluorescence is important for visual discrimination of conspecifics by Heliconius erato

DOI: 10.1242/jeb.153593
Abstract: ABSTRACT Toxic Heliconius butterflies have yellow hindwing bars that – unlike those of their closest relatives – reflect ultraviolet (UV) and long wavelength light, and also fluoresce. The pigment in the yellow scales is 3-hydroxy-dl-kynurenine… read more here.

Genomic evidence reveals three W-autosome fusions in Heliconius butterflies

DOI: 10.1371/journal.pgen.1011318
Abstract: Sex chromosomes are evolutionarily labile in many animals and sometimes fuse with autosomes, creating so-called neo-sex chromosomes. Fusions between sex chromosomes and autosomes have been proposed to reduce sexual conflict and to promote adaptation and… read more here.
