Hybridization allows adaptations to be shared among lineages and may trigger the evolution
of new species,. However, convincing examples of homoploid hybrid speciation remain rare …

Sex pheromones in many insect species are important species-recognition signals that
attract conspecifics and inhibit attraction between heterospecifics; therefore, sex …

Studies of female mate choice commonly use virgin females as test subjects, either to control
for the effects of mating or because virgin females are presumed to be more responsive to …

Studies of adaptive radiations have played a central role in our understanding of
reproductive isolation. Yet the focus has been on human-biased visual and auditory signals …

Natural selection is notoriously dynamic in nature, and so, too, is sexual selection. The
interactions between phytophagous insects and their host plants have provided valuable …

Abstract The Heliconiini genera Agraulis and Dryas are widely distributed throughout the
Neotropics and into adjacent temperate regions, and although they are currently treated as …

Many animal species remain separate not because their individuals fail to produce viable
hybrids but because they “choose” not to mate. However, we still know very little of the …

Sexual traits that promote species recognition are important drivers of reproductive isolation,
especially among closely related species. Identifying neural processes that shape species …

Covering: 1990 up to 2022 Contrary to popular opinion, butterflies exhibit a rich chemistry
and elaborate use of volatile compounds, especially for sexual communication, but also for …

Chemosensory communication is essential to insect biology, playing indispensable roles
during mate-finding, foraging, and oviposition behaviors. These traits are particularly …
