Repeated mating by females of many species occurs at frequencies in excess of those needed to acquire additional sperm for fertilizing ova. I tested three alternative hypotheses for the rate of remating by females of the courtship-feeding tree cricket, Oecanthus nigricornis Walker, by manipulating diet quality and courtship feeding and measuring the time to remating by the female in relation to four aspects of male phenotype (age, condition, fluctuating asymmetry, and size). First, in courtship-feeding species, remating may be due to selection to increase the amount of nutritional resources provided by males, with nutrient-deprived females remating more quickly. Second, remating may function as a mechanism of postcopulatory mate choice, with females remating quickly when the quality of a previous mate is low. Third, quickness of remating may be the consequence of precopulatory mate choice prior to future …
