“…Behaviors arising from sexual conflict are widespread in animals ( Arnqvist and Rowe 2005 ), including sexual coercion by males, who physically force females into unwanted copulation in insects, isopods, fish, reptiles, and mammals ( Sparkes et al 1996 ; Watson-Capps 2009 ; Rossi et al 2010 ; Takahashi and Watanabe 2010 ; Tsurui-Sato et al 2019 ; Iglesias-Carrasco et al 2020 ; Moldowan et al 2020 ; Smit et al 2022 ), and sexual cannibalism by females, who attack and consume males at some stage during courtship or mating and documented in many arthropods including mantises, spiders, crickets, amphipods, copepods, and some gastropods ( Elgar 2004 ; Burke and Holwell 2021 ). Although female sexual catalepsy might initially seem to reflect a case of male-controlled sexual conflict, our experiments suggest that it is under female control and benefits both females and males.…”

Theory predicts that males and females of dioecious species typically engage in an evolutionary sexual conflict over the frequency and choice of mating partner. Female sexual cannibalism, a particularly dramatic illustration of this conflict, is widespread in certain animal taxa including spiders. Nevertheless, females of some funnel weaving spiders that are generally aggressive to conspecifics enter a cataleptic state after male courtship, ensuring the males can mate without risk of attack. In this study, we demonstrated that the physical posture and duration, metabolites and central neurotransmitters of females of Aterigena aculeata in sexual catalepsy closely resemble females in thanatosis but are distinct from those in anaesthesia, indicating that the courted females feign death to eliminate the risk of potentially aggressive responses and thereby allow preferred males to mate. Unlike the taxonomically widespread thanatosis, which generally represents a deceptive visual signal that acts against the interest of the receivers, sexual catalepsy of females in the funnel weaving spiders may deliver a sexual-receptive signal to the courting males and thereby benefit both the signal senders and receivers. Therefore, sexual catalepsy in A. aculeata may not reflect a conflict but rather a confluence of interest between the sexes.

Sex- and trait-specific silver-spoon effects of developmental environments, on ageing

The environment organisms experience during development can have effects which carry over into their adult lives. These environments not only affect adult traits at a given point in time, but also how these traits change with age. Generally, favorable developmental environments lead to more optimal adult traits while stressful environments are deleterious ("silver-spoon effect"). But whether developmental environments affect how whole-organism performance traits change with age or whether they affect males and females differently lacks evidence. Here, we test whether experiencing favorable developmental environments leads to "silver-spoon effects" on life-history traits and whole-organism flight performance of males and females by manipulating developmental density in Callosobruchus maculatus. We further test whether such effects are mediated by an individual's reproductive status by comparing traits of mated versus virgin females. We show that although developmental crowding has no effect on flight performance of either sex, on male adult lifespan, or on female age-dependent survival, it is detrimental to female lifespan and fecundity, as well as female age-dependent reproduction, suggesting that females are more sensitive to differences in developmental density. Additionally, we show that flight traits change with age and differ not only between males and females, which is reflective of sex-specific lifehistories and behavior, but also between virgin and mated females. Our study is important for understanding sex-specific responses to developmental environments in life-history, behavioral, and ecologically important traits which may affect resource allocation, dispersal, and mating strategies, hence fitness.
