Understanding the evolution of premating isolation in the early stages of population divergence is a major challenge. Context-dependent mate preferences can influence both population fitness and drive evolutionary change and populationdivergence. Here, studied premating isolation through quantifying female mate preferences for resident and immigrant males within and between populations of a colour polymorphic insect. Closely located populations differ in densities, female fecundity and community composition. Females showed context-dependent mate preferences: in a high-density year they preferred immigrant males, whereas in a low-density year, this preference was reversed, and females instead preferred resident males. We suggest that context-dependent female mate preferences are shaped by variation in male density between years and that the intensity of sexual conflict causes shifts in the sign and magnitude of premating isolation between populations.
