Females mate several times in many butterfly species. In these so called polyandrous butterflies, males deliver heavier and more nutrient rich ejaculates than males in species where females mate only once. Recent studies show that polyandry in butterflies functions as a system where males transfer nutrients which the female is in short supply of, and is later used by females to boost reproductive performance and somatic maintenance. This suggests that males in polyandrous species are selected…

Sexual conflict and cooperation in butterfly reproduction: a comparative study of polyandry and female fitness
TLDR
Female reproductive output, measured as cumulative egg mass divided by female mass, increased significantly with polyandry, demonstrating that the positive effect of mating rate on female reproductive fitness also holds between species.
Unpredictable environments, nuptial gifts and the evolution of sexual size dimorphism in insects: an experiment
TLDR
Differences in environmental conditions between species may act as an important factor in the evolution of the mating system and sexual size dimorphism.
Male mating history and female fecundity in the Lepidoptera: do male virgins make better partners?
TLDR
A meta-analysis using data from 29 studies of 25 species found that the reproductive output of females mated to virgin males was significantly higher than that of femalesmated to sexually experienced males, and possible reasons why male mating history, presumably acting through its effect on spermatophore size, might have a stronger effect in polyandrous than monandrous species are discussed.
Decoupling of reproductive rates and parental expenditure in a polyandrous butterfly
TLDR
It is shown that the relative degree of parental expenditure in of&pring is largely decoupled from the degree of mating competition in P. napi, where the male reproductive rate is 8-13 times higher than that of females.
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
Sexual con ict and cooperation in butter y reproduction : a comparative study of polyandry and female tness
Most butter£y species can be characterized as capital breeders, meaning that reproductive output is strongly coupled to the amount of resources they have procured during the larval stage.
Strategic sperm allocation in the Small White butterfly Pieris rapae (Lepidoptera: Pieridae)
TLDR
It can be argued that Small White butterfly males allocate sperm strategically according to the probability of obtaining subsequent matings, and the level of sperm competition.
Effects of mating history on ejaculate size, fecundity, longevity, and copulation duration in the ant-tended lycaenid butterfly, Jalmenus evagoras
TLDR
The hypothesis that multiple mating by males imposes physiological costs resulting in smaller spermatophores, and that this results in a fitness cost to females is tested, and it is found that male J. evagoras transferred only 2.2% of their eclosion weight during their first mating, consistent with the hypothesis that males of monandrous species produce a relatively small investment.
Do male seminal donations shape female post-mating receptivity in a usually monandrous moth?
TLDR
It is found that laboratory strain males were significantly less efficient than field strain males at inhibiting female PMR, and that such variation covariate with the polyandry level of the parental strain, suggesting that there is genetic variation in ejaculate composition-mediated male ability to influence/manipulateFemale PMR.
Sex-specific response to nutrient limitation and its effects on female mating success in a gift-giving butterfly
TLDR
It is found that as predicted females, but not males, sacrifice allocation to reproduction when larval dietary nitrogen is limited, and it is suggested that female mating frequency is constrained by male mate choice based on females’ wing coloration.

TLDR
It is suggested that adult females of polyandrous species have a higher expected nutrient income and are consistent with the idea that females can benefit from male nutrient donations transferred during mating.
Reproductive strategies of female butterflies: variation in and constraints on fecundity
TLDR
It is proposed that the shape of the age‐specific fecundity curve for each species under optimal conditions is constrained by the potential importance of adult nutrients in egg production.

TLDR
A comparative examination, among related organisms, of the interactions between investment patterns and life history will yield testable hypotheses concerning the forces which have determined current reproductive investment patterns.
Sexual Selection and Paternal Investment in Insects
TLDR
It is hypothesize that female preference for greater male parental investment may have been the selective context for the evolution of all types of male investment patterns in insects.
Paternal investment in a monandrous butterfly, Pararge aegeria
TLDR
This study supports the view that males incur non-trivial costs in producing ejaculates, and proposes differences in degree of sperm competition between species as a possible explanation for differences in male investment.
Reproductive patterns and resource allocation in tropical butterflies : influence of adult diet and seasonal phenotype on fecundity, longevity and egg size
TLDR
It is tentatively concluded that diapause imposes a substantial cost to reproduction, and this cost is the result of an adjustment in resource allocation between soma (body size and structure to increase longevity) and reproductive reserves acquired during the larval feeding period.
The Cost of Prolonged Life: An Experiment on a Nymphalid Butterfly
TLDR
The results suggest that the structures of organisms are adjusted to their life expectancies, and, everything else being equal, longer-lived organisms will have less resources for producing offspring than those with shorter life- Expectancies.
Increase in reproductive effort as explained by body size and resource allocation in the speckled wood butterfly, Pararge aegeria (L.).
TLDR
Investigation of resources allocated to soma vs reproductive reserves at adult eclosion in a satyrine butterfly Pararge aegeria reveals that heavy females have a proportionately higher lifetime fecundity compared to light females, and longevity among both males and females is influenced by sucrose feeding.
Male Nutrient Investment in the Lepidoptera: What Nutrients Should Males Invest?
TLDR
Gwynne has devised a workable division of reproductive effort by retaining definitions of mating effort and parental effort but dividing mating effort into promiscuous and nonpromiscuous mating effort.
Unpredictable food and sexual size dimorphism in insects
TLDR
It is suggested that food variability, causing some males to have much to provide and some females to be in great need, would be conducive to the evolution of such a mating system, and comparative data on butterflies supporting the suggestion is presented.
