Its mating system relies on heterospecific matings with males of closely related sexual species. In mixed popu- lations, males mate with conspecific sexual females and heterospecific asexual females. Such matings are not isolated dyadic interactions but rather elements of a communication net- work, because multiple females can observe these interactions. This is the only known case of heterospecific mate-copying and, thus, a system in which the potential for mate-copying could be influenced by the presence of another species. Here we show that mate-copying is exhibited by the sexual species P. mexicana and P. latipinna , and the asexual P. formosa . Both sexual and asexual females copy each other’s mate choice decisions in sympatry, but females from allopatric populations do not show
