Males of many animals provide females with 'nuptial gifts', such as prey items or glandular secretions, during courtship and mating. Traditionally, nuptial feeding is viewed as a form of paternal investment in offspring. Although other explanations have been proposed, the focus remains gender-specific, with a male donor and female recipient. Here we show that females of the extraordinary insect Phoreticovelia disparata provide food for males during mating. This previously undescribed reversal… 

Sex-role reversed nuptial feeding reduces male kleptoparasitism of females in Zeus bugs (Heteroptera; Veliidae)

TLDR
It is suggested that females have, at least in part, evolved this unique form of nuptial feeding as a counteradaptation to reduce the rate of kleptoparasitism by males.

The extraordinary mating system of Zeus bugs (Heteroptera : Veliidae : Phoreticovelia sp.)

TLDR
Natural history details of the mating behaviour for two Zeus bug species are provided and it is suggested that it adds to those studies showing that sexually antagonistic coevolution can be a driver of mating system evolution.

The role of male's anal horns in copulation of a scorpionfly

TLDR
The anal horns of male D. magna seem to be a male adaptation evolved to overcome female mating resistance, by promoting male domination in copulation through increasing the duration of pre- and post-gift-providing copulatory stages against female resistance and by avoiding wasting of nuptial gifts.

The Evolution of Animal Nuptial Gifts

Daring females, devoted males, and reversed sexual size dimorphism in the sand-dwelling spider Allocosa brasiliensis (Araneae, Lycosidae)

TLDR
Findings on the sand-dwelling wolf spider, Allocosa brasiliensis, prove a reversal in typical courtship roles reported for the first time in spiders, turning it as a promising model for discussing the determinants of sex roles and the pressures that drive their evolution and maintenance.

Death feigning in the face of sexual cannibalism

TLDR
It is proposed that death feigning evolved as an adaptive male mating strategy in conjunction with nuptial gift giving under the risk of being victimized by females.

Extreme cost of male riding behaviour for juvenile females of the Zeus bug

Size-assortative pairing across three developmental stages in the Zeus bug, Phoreticovelia disparata

TLDR
It is proposed that size-assortative pairing arises through adaptations that have evolved to minimise the potential costs of sexual conflict and that the selective pressure on males to maximise survival benefits is sufficiently high that it outweighs the reproductive benefits of discriminating against fourth instar females.

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.

TLDR
Evidence for the potential ofnuptial gifts to function as either paternal investment, mating effort, or both is reviewed for each form of nuptial feeding in each insect taxon for which sufficient data are available.

Courtship feeding increases female reproductive success in bushcrickets

TLDR
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.

The evolution of polyandry: multiple mating and female fitness in insects

TLDR
A meta-analysis of 122 experimental studies addressing the direct effects of multiple mating on female fitness in insects shows that females gain directly from multiple matings in terms of increased lifetime offspring production, and supports the existence of an intermediate optimal female mating rate.
