Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

Social behaviour emerges from the local environment but is constrained by the animal's life
history and its evolutionary lineage. In this perspective, we consider the genus Drosophila …

Interactions between species can alter selection on sexual displays used in mate choice
within species. Here we study the epicuticular pheromones of two Drosophila species that …

The evolution and maintenance of intraspecific communication channels constitute a key
feature of chemical signalling and sexual communication. However, how divergent chemical …

Pheromones play an important role in the behavior, ecology, and evolution of many
organisms. The structure of many insect pheromones typically consists of a hydrocarbon …

Sexual selection within populations can play an important role in speciation when
divergence in mating signals and their corresponding preferences occur along different …

Cuticular hydrocarbons (CHCs) are organic compounds found on the cuticles of all insects
which can act as close‐contact pheromones, while also providing a hydrophobic barrier to …

Discrimination of particular species within the species complexes of tephritid fruit flies is a
very challenging task. In this fruit-fly family, several complexes of cryptic species have been …

Insect cuticular hydrocarbons (CHCs) are organic compounds of the surface lipid layer,
which function as a barrier against water loss and xenobiotic penetration, while also serving …

Background Individuals commonly prefer certain trait values over others when choosing
their mates. If such preferences diverge between populations, they can generate behavioral …
