In non-chosen pairs, 16percentt of courtships led to copulation, which was only slightly lower than the rate of 20percentt in chosen pairs.
Post-oviposition copulations, which are generally rare but typical for sepsid flies [ 32, 44], make advantages of injuring females during mating even less plausible: from a male perspective, females have to survive until they lay their next clutch because only then will females use the damaging male's sperm, but harming females reduces the likelihood they will survive to this point.
In a recent study, Mazzi et al. [ 38] showed that in Finnish D. montana sexual conflict arises in the length of copulation duration, which is primarily under female control.
Conversely, for copulation latency, which is controlled by females in D. melanogaster (females actively reject males and thus demonstrate active mate choice; Connolly and Cook 1973), a female genotype effect signals genetic variation in female preference, and a male genotype effect indicates genetic variation in male attractiveness.
And it's known that male orangutans regularly force copulation on females, which is hard not to see as rape.
Male genotype significantly contributed to the amount of variation in copulation duration, a result which is consistent with theory and previous evidence that this trait is primarily under male control [ 51].
The females of basal moths have only one sex organ, which is used for copulation and as an ovipositor, or egg-laying organ.
Indeed, precopulatory violent shaking by the male seems to increase the female's need for oxygen which is followed by copulation when the female is exhausted and non-resisting [30].
Conflicts also exist in the distribution of characters of the fan, a lateral extension of the cuticle at the male tail which is used during copulation.
However, if the female moves and attempts to terminate copulation, the male may perform "thanatosis" which is a "death feigning" behaviour (with stretched-out legs) unique to this species.
