In mating systems that are characterized by resource-dependent male behavior like nuptial feeding, food limitation obviously plays a major role in male performance. In Panorpa vulgaris (Mecoptera: Panorpidae), the ability to produce nuptial gifts has major fitness consequences as the number of gifts determines copulation duration, which then determines the number of eggs fertilized by a given male. In the present study, we are able to show that males of P. vulgaris were limited in their… Expand
Nuptial feeding in the scorpionfly Panorpa vulgaris: maintenance of genetic variance in sexual advertisement through dependence on condition influencing traits
TLDR
The results demonstrate that estimates of Va in sexual signals (especially if estimated using standardised breeding conditions) will be strongly influenced by the presence/absence of environmental factors related to male performance in natural selection context. Expand
When are vomiting males attractive? Sexual selection on condition-dependent nuptial feeding in Drosophila subobscura
TLDR
The findings suggest that, in this monandrous species, selection has favored males who invest innuptial gifts, possibly as an example of paternal investment as well as mating effort, but that the strength of selection on nuptial feeding is strongly subject to environmental variation. Expand
A secondary sex trait under construction: age‐ and nutrition‐related salivary gland development in a scorpionfly (Insecta: Mecoptera)
TLDR
It is shown that saliva production did not start before adult emergence, that the state of development of salivary glands was affected by larval nutrition as well as by adult nutrition and, moreover, by age, and older individuals had developed glands of greater mass than had younger animals. Expand
Energy beyond the pupal stage: larval nutrition and its long-time consequences for male mating performance in a scorpionfly.
TLDR
It is shown that food availability during larval development affected male body weight and that there was an interaction between larval and adult diet affecting salivary gland weight relative to body weight. Expand
Sexual selection, ecology, and evolution of nuptial gifts in spiders
TLDR
Studies on the function and evolution of nuptial gifts, particularly comparing the neotropical with the Palearctic species, are reviewed, and evolutionary implications of nuPTial gifts for males and females are discussed. Expand
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. Expand
Condition dependence of male nuptial gift construction in the spider Pisaura mirabilis (Pisauridae)
TLDR
It is shown that poor feeding condition affects pre-copulatory gift construction behaviour and nuptial gift construction may be an honest indicator of male condition and therefore a target of female choice. Expand
Nuptial gift size, mating duration and remating success in a Neotropical spider
TLDR
It is shown that large gifts prolong mating duration in P. ornata, supporting the mating effort hypothesis, and females would favour polyandry to gain direct benefits from the gifts, while males may improve success in sperm competition by inducing female reluctance for remating. Expand
Male preferences for nuptial gifts and gift weight loss amongst the nursery web spider, Pisaura mirabilis
TLDR
Males showed strong preferences for large prey compared to small prey for gift production, which is likely to be more attractive for females and provide males with longer copulation, and males in poor body condition reduced the cost of gift production by feeding on the prey, supporting the idea that nuptial feeding is condition dependent. Expand
Nutrition‐ and sex‐dependent utilization of body resources in relation to reproduction in a scorpionfly
TLDR
It is demonstrated that food availability does influence investment in flight muscle development in scorpionflies, and the build-up of the thoracic muscles was strongly influenced by nutrient availability. Expand

Nuptial feeding by male bushcrickets: an indicator of male quality?
TLDR
Male quality does influence nuptial feeding, but in a manner predicted by a model of indirect fitness benefits from mate choice, and males with high levels of fluctuating asymmetry invested more heavily in the nutritional content of their spermatophylaxes than did symmetrical males. Expand
Mating System and Sexual Selection in the Scorpionfly Panorpa vulgaris (Mecoptera: Panorpidae)
TLDR
New data are presented that clearly show that the mating system of P. vulgaris is not simply a resource-defense polygyny, as has previously been thought, and four main predictions of the indicator model of the theory of sexual selection of Panorpa vulgaris are confirmed. Expand
The function of nuptial feeding in insects: a review of empirical studies
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. Expand
Nutritional Status of Males and Sperm Transfer in the Scorpionfly Panorpa vulgaris (Mecoptera: Panorpidae)
TLDR
The results indicate that within the scope of food availability tested in the present study it is not possible to decide clearly whether sperm supply is nutritionally limited, however, the great inter-male variation in the number of sperm transferred to the FF' spermatheca is consistent with the hypothesis that the sperm supply of some MM is limited. Expand
A life-history perspective on strategic mating effort in male scorpionflies
TLDR
The results imply that males adaptively change their resource allocation strategy during the course of the season, and initial matings seem to be characterized by male prudence; in later matings, males seem to adopt a more opportunistic mating strategy. Expand

TLDR
Only males in poor condition choose cryptically, producing larger salivary masses in copulations with females of high fecundity, and this prediction is examined in the scorpionfly Panorpa cognata. Expand
Genetic sire effects on the fighting ability of sons and daughters and mating success of sons in a scorpionfly
TLDR
Field-collected males of the scorpionfly Panorpa vulgaris were separated on the basis of whether or not they could produce salivary nuptial food during matings in the laboratory to reflect differences in the ability of the two types of males to compete with conspecifics for food in the habitat.

Molecular genetic analysis of remating frequencies and sperm competition in the scorpionfly Panorpa vulgaris (Imhoff and Labram)
TLDR
Paternity analyses of scorpionfly females showed that females allocate paternity in proportion to male copulation duration, and remating and sperm mixing may allow females to gain "high quality" genes for their offspring when females adjustCopulation duration to male quality. Expand
Sperm Competition and Its Evolutionary Consequences in the Insects
TLDR
It is testimony to Simmons’hard-nosed empiricism that he pays more attention to questions from the traditional‘male perspective’ on why femalesmate multiply. Expand

TLDR
Paternity data and morphological evidence accorded best with a model of partial sperm displacement derived here, and how female control of sperm transfer and intraspecific variation in sperm precedence may be important precursors to the evolution of gift giving in insects is discussed. Expand
