Are there any benefits to copulating? There are several factors to consider when deciding whether to initiate this sexual activity. Males produce broadband buzzing sounds while copulating, which are highly audible to bats. In one study, five per cent of male flies were attacked by bats. Over four observation years, this number rose to 26 per cent. While many animals are able to detect and avoid such sounds, the process of copulation is an essential part of a successful mating.
Sexual conflict has led to the evolution of different mating traits, such as the ability to prevent a female from remating. Some studies have even shown that certain males have evolved pre-copulatory traits that restrict the female’s ability to remate. While these behaviors are not strictly necessary for reproduction, they do appear to circumvent the decisions of a female during mating. For example, males who copulate with females who have just moulted may avoid their mating attempts by using a male’s spines to prevent them from remating. These unusual mating practices may lead to confusion and even sexual conflict.
While longer first-mating times were associated with higher P2 scores, shorter first-mating periods were less successful than longer-lasting copulations. Copulation duration may have an effect on sperm uptake in subsequent matings, which may create a trade-off between sperm offense and defense. Further research is needed to determine the role of copulation duration in mating. Copulation duration could also influence the number of offspring a female produces during mating.
