It is well known that sexual selection can target reproductive traits during successive pre‐
and post‐mating episodes of selection. A key focus of recent studies has been to understand …

Genetic correlations between traits determine the multivariate response to selection in the
short term, and thereby play a causal role in evolutionary change. Although individual …

The insect integument is covered by cuticular hydrocarbons (CHCs) which provide
protection against environmental stresses, but are also used for communication. Here we …

Highlights•Communication via chemical signals, that is, pheromones, is of pivotal
importance for most insects.•Most insects pheromones evolved from precursor compounds …

Chemical communication is the most ancient and widespread form of communication. Yet
we are only beginning to grasp the complexity of chemical signals and the role they play in …

Recent research has demonstrated extensive within-species variation in pheromone
expression in insect species, contrary to the view that pheromones are largely invariant …

Sexual selection can increase rates of adaptation by imposing strong selection in males,
thereby allowing efficient purging of the mutation load on population fitness at a low …

While the reproductive benefits of sexual displays have been widely studied, we have
relatively limited evidence of the fitness costs associated with most display traits. Insect …

The role that genotype‐by‐environment interactions (GEIs) play in sexual selection has only
recently attracted the attention of evolutionary biologists. Yet GEIs can have profound …

Same-sex sexual behaviour (SSB) is widespread across taxa. One adaptive hypothesis to
explain the occurrence and maintenance of SSB is that it acts to intensify or diminish …
