Sexual selection has resulted in some of the most captivating features of insects, including
flashy colors, bizarre structures, and complex pheromones. These features evolve in …

The evolution of male preferences and of female ornaments in species with traditional sex
roles (ie, polygyny) have been highlighted as areas in need of more active research by an …

Intersexual signals that reveal developmental or mating status in females have evolved
repeatedly in many animal lineages. Such signals have functions in sexual conflict over …

Sexual selection is often assumed to be strong and consistent, yet increasing research
shows it can fluctuate over space and time. Few experimental studies have examined …

We review experimental and theoretical evidence that learning in insects and spiders affects
the expression of mate preferences and of sexual signals, the evolution of both traits, and …

Sex-limited morphs can provide profound insights into the evolution and genomic
architecture of complex phenotypes. Inter-sexual mimicry is one particular type of sex-limited …

Background Establishment of geographic morph frequency clines is difficult to explain in
organisms with limited gene flow. Balancing selection, such as negative frequency …

Animal communication relies on conspicuous signals and compatible signal perception
abilities. Good signal perception abilities are particularly important for polymorphic animals …

In the Asian citrus psyllid, Diaphorina citri Kuwayama, stimulatory cuticular hydrocarbons act
as sex pheromone attractants. Male psyllids locate aggregations of females using those …

Conspicuous female coloration can evolve through male mate choice or via female-female
competition thereby increasing female mating success. However, when mating is not …
