===Intrasexual selection===
Male black swallowtails can sometimes mimic the female wing-back pattern, and therefore succeed in reduced predation as well.<ref name=":2" /> However, males of the typical coloration are more successful in [[Male intrasexual competition|intrasexual competition]] for mating territories compared to the males who mimic the female wing pattern.<ref name=":2" /> Females have no preference based on wing markings, and are equally likely to mate with a typical versus an alternative coloration.<ref name=":2" /> Therefore, male-male [[intrasexual selection]] is of greater importance than female [[mate choice]] in maintaining the classic male wing-back coloration and pattern.<ref name=":2">{{cite journal|last=Lederhouse|first=Robert C.|author2=J.
