Males’ reproductive successes are often limited by access to mates, whereas females’ reproductive successes are more often limited by access to resources. Thus, for a given sexual encounter, it benefits the male to mate, but benefits the female to be choosy and resist. For example, male small tortoiseshell butterfly co...
