“…When male`quality' was controlled, females did not reject loaded males more often than unloaded males. However, at least when sex ratio was equal, male courting intensity seemed to be the main determinant of their mating frequency, as has been previously noted in some ¢sh (Jamieson & Colgan 1989;Knapp & Kovach 1991) and a butter£y species (Kaitala & Wiklund 1995). In those cases, the evidence of active female choice may be lacking or be undetectable (Jamieson & Colgan 1989;Andersson 1994).…”

In several species of ¢sh, females select males that are already guarding eggs in their nests. It is a matter of debate as to whether a female selects a good nest site for her o¡spring (natural selection) or a male for his attractiveness (sexual selection). The golden egg bug, Phyllomorpha laciniata Vill, resembles ¢sh in the sense that mating males carry more eggs than single males, but in the bugs, female mate choice is decoupled from egg site choice. The sexual selection hypothesis predicts that if females select males using male egg load as a cue for male quality, they should not mate with a male when eggs are removed, regardless of his mating attempts. When individual females were enclosed with an egg-loaded male and an unloaded male, they mated equally often with both males, although the loaded males courted more. In addition, when only successful males were used, females mated equally often with the loaded male and the unloaded male irrespective of sex ratio. Male choice rather than female choice a¡ected mating frequency when sex ratio was equal. Therefore, females do not select the male by the eggs he carries, but successful males may receive many eggs due to egg dumping by alien females while they mate or as a consequence of mate guarding.

“…In lepidopteran species, virgin males generally transfer larger spermatophores than recently mated males (Kaitala & Wiklund, 1994;Cook, 1999;Watanabe & Hirota, 1999;Hughes et al, 2000) and these larger spermatophores can increase female refractory time, thus reducing the likelihood of females remating (Kaitala & Wiklund, 1995, and references therein). Female Pieris napi, for example, that were paired in the laboratory with mated males, had higher mating frequencies than females mated with virgin males (Kaitala & Wiklund, 1994).…”

Abstract. The degree of polyandry in a species is linked to other life history traits such as egg maturation, life span, and male ejaculate size and quality. The study of differences in mating strategies between closely related species can provide a better understanding of the evolution of these strategies and of sperm competition. Mating patterns of two closely related species of small ermine moths (Yponomeuta) were investigated in the laboratory. The average female age at first mating was higher in Y. cagnagellus than in Y. padellus. Both species mated more than once; however, Y. cagnagellus females were more likely to remate in a short time frame. Moreover, Y. cagnagellus had higher life time female mating frequencies than Y. padellus (viz., 3.0 versus 2.0). These differences in mating frequency were confirmed in the field by examining the presence of spermatophores (or their remains) in the bursa as well as sperm in the spermatheca of field-caught females.

“…To generate males providing varying amounts of nutrients to the female we used the fact that once-mated Pieris napi males provide a significantly smaller spermatophore (the sperm packet including nutrients) on their second mating than do virgin males (Kaitala & Wiklund 1995). A similar decline in spermatophore size with mating has been shown in several other butterfly species (reviewed in Vahed 1998).…”

Paternal investment directly affects female reproductive effort in an insect

Female reproductive effort can be influenced by the quality of her mate. In some species, females increase their reproductive effort by differentially allocating resources after mating with high-quality males. Examination of female reproductive effort in relation to male quality has implications for estimating the evolvability of traits and for sexual-selection models. Accurate quantification of reproductive investment is not possible in many species. Butterflies are an exception, as most nectar-feeding species emerge with almost intact reproductive resources, and in some species males provide nutrients at mating that enhance female fecundity. By manipulating male donations and using radioactive isotopes, we quantified the effect of variation in nutrient provisioning on female reproductive effort in two butterfly species. In the greenveined white butterfly, Pieris napi, females increased their reproductive effort after receiving large male donations. By contrast, in the speckled wood, Pararge aegeria, where males do not provide nutrients, female reproductive effort was independent of male ejaculate. Increased reproductive effort in Pieris napi resulted from the production of more eggs, rather than from investing more resources per egg. In this species donating ability is heritable; hence females laying more eggs after mating with high-donating males benefit both through higher fecundity and through the production of high-donating sons.
