SummaryFor species exhibiting courtship feeding it is typically argued that the food gift presented by males is a sexually-selected trait in serving to acquire fertilizations. An alternative hypothesis is that the trait is maintained by natural selection for parental investment in which the fitness of the mating male's offspring is increased. Here I argue that the spermatophylax, a nutritious part of the spermatophore provided to female katydids, Requena verticalis, functions mainly as parental… 

Functions of courtship feeding in black-legged kittiwakes: natural and sexual selection

It is suggested that courtship feeding in kittiwakes could have first evolved under natural selection and subsequently may have become a signal of male quality that females could use to evaluate their mates for future seasons (future mate appraisal hypothesis).

Results of some experiments are reported that show that the positive effects of nutrient donation on female reproduction for one species of spermatophylax producing tettigoniid can be realized within 24 to 48 h.

Polyandry in the wild: temporal changes in female mating frequency and sperm competition intensity in natural populations of the tettigoniid Requena verticalis

Microsatellite markers are used to provide rare estimates of female mating rates and patterns of parentage in a species of tettigoniid, Requena verticalis, which has been used extensively to test theory on the evolution of male parental investment and its influence on the direction of sexual selection.

Nuptial Feeding in Insects: Theoretical Models of Male and Female Interests

A series of prospective models of nuptial feeding for insects suggest that gift donation is most likely to evolve when (1) giving a gift has little effect on male, but a significant effect on female survival, (2) when the male is more likely to father eggs in a later batch, rather than the next batch, and (3) when random mortality is high.

Polyandry and its effect on female reproduction in the green-veined white butterfly (Pieris napi L.)

Although the nutrient investment of the first male to mate with a female “subsidizes” the progeny of later-mating males, the male nuptial gift in P. napi clearly qualifies as both paternal investment and mating effort.


There was a negative phenotypic correlation between male chirp rate and chirP duration, suggesting that females may have to trade off the life span and reproduction benefits when selecting a mate.

Comparison, experimental, and natural history evidence reveal that most edible gifts of prey or glandular products provide direct benefits to females, and points out the difficulties in determining that female remating rates are suboptimal.

The effects of male phenotypic condition on reproductive output in a sex role-reversed beetle

Weighing costs and benefits of mating in bushcrickets (Insecta: Orthoptera: Tettigoniidae), with an emphasis on nuptial gifts, protandry and mate density

The view that tettigoniids provide excellent models to test and understand the economics of matings in both sexes is reinforced, focussing on nuptial gifts, their trade-off with male calling songs, protandry and how mate density influences mate choice.



Courtship Feeding in Katydids (Orthoptera: Tettigoniidae): Investment in Offspring or in Obtaining Fertilizations?

The hypothesis that the function of "excess" maledonated nutrition is mating effort that protects the ejaculate is rejected and courtship feeding in R. verticalis may represent parental effort whereby males invest in their own zygotes.

Courtship feeding increases female reproductive success in bushcrickets

Results are reported of an experiment which shows that feeding on the spermatophore enhances the reproductive success of female bushcrickets by increasing the numbers and size of eggs produced.

Sexual Selection and Paternal Investment in Insects

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.

Sexual selection and its consequences at different sites are examined by testing the prediction that sexual selection on females, as estimated by variance in mating success, should be greater at sites where sexual competition among females is observed and detailing the differences in courtship behavior between sites that have apparently resulted from differences in sexual selection.

This species has a large spermatophore, a product of male reproductive glands, that is eaten by the female after mating, and the mating behaviour of the katydid Metaballus sp.

Katydid males (Requena verticalis) produce spermatophores with a large sperm‐free sperMatophylax, which is eaten by the female after mating, and this male‐produced food substitute for other food in the diet of the female or is it a source of specialized nutrients.

Symposium: Insect Behavioral Ecology--85: Prezygotic Male Reproductive Effort in Insects: Why do Males Provide More Than Sperm?

If male-provided benefits (prezygotic or otherwise) are more costly than female costs of offspring production, reproductively-ready males will act as resources limiting female reproduction.

Female G. bimaculatus may control the degree of sperm competition as a mechanism of mate choice by accepting large quantities of sperm from chosen males and determining the paternity of their offspring by diluting out the sperm stored from previous matings.

Paternal Investment by Terrestrial Arthropods

The indirect sperm transfer strategies common to many terrestrial arthropod species seem to preclude males from contributing materially to their offspring by dissociating parent from progeny, which may explain in part the relative paucity of high levels of paternal investment by terrestrialArthropods.
