“…We paired a randomly selected adult female spider aged 3 days post-maturation either from Group HL or Group LL with a randomly selected field-collected adult male. We used the field-collected males because they are polygynous ( Zhao 1993 ; Gong et al 2019 ) and we could ensure all males were of relatively high quality compared with the laboratory-reared males ( Zhao 1993 ; Jiang et al 2018 ). We also controlled the possible interaction between female and male diets.…”

As predators, the macronutrients spiders extract from their prey play important roles in their mating and reproduction. Previous studies of macronutrients on spider mating and reproduction focus on protein, the potential impact of prey lipid content on spider mating and reproduction remains largely unexplored. Here we tested the influence of prey varying in lipid content on female mating, sexual cannibalism, reproduction and offspring fitness in the wolf spider Pardosa pseudoannulata. We acquired two groups of fruit fly Drosophila melanogaster that differed significantly in lipid but not protein content by supplementing cultural media with a high or low dose of sucrose on which the fruit flies were reared (HL: high lipid; LL: low lipid). Subadult (i.e., one molt before adult) female spiders that fed HL flies matured with significantly higher lipid content than those fed LL flies. We found that the mated females fed with HL flies significantly shortened pre-oviposition time and resulted in a significantly higher fecundity. However, there was no significant difference in female spiders varying in lipid content on other behaviors and traits, including the latency to courtship, courtship duration, mating, copulation duration, sexual cannibalism, offspring body size and survival. Hence, our results suggest that the lipid content of prey may be a limiting factor for female reproduction, but not for other behavioral traits in the wolf spiders P. pseudoannulata.

“…In linyphiids, for example, initial copulation without transfer (pseudocopulation) is followed by a sequence of transfers and inductions [54,111]. In other spiders, induction occurs shortly after copulation [112] or at some point between matings with different females [65,113]. The associated costs of recharging the pedipalps may also vary.…”

Aggressive and cannibalistic female spiders can impose strong selection on male mating and fertilization strategies. Furthermore, the distinctive reproductive morphology of spiders is predicted to influence the outcome of sperm competition. Polyandry is common in spiders, leading to defensive male strategies that include guarding, plugging and self-sacrifice. Paternity patterns are highly variable and unlikely to be determined solely by mating order, but rather by relative copulation duration, deployment of plugs and cryptic female choice. The ability to strategically allocate sperm is limited, either by the need to refill pedipalps periodically or owing to permanent sperm depletion after mating. Further insights now rely on unravelling several proximate mechanisms such as the process of sperm activation and the role of seminal fluids. This article is part of the theme issue ‘Fifty years of sperm competition’.
