Despite a massive research effort, our understanding of the
evolution of female mate choice remains incomplete [1, 2].
A central problem is that the predominating empirical
research tradition has focused on male traits, yet the key
question is whether female choice traits are maintained
because of direct effects on female fitness or because of indi-
rect genetic effects in offspring that may be associated with
such traits. Here, we address this question by using a novel
research strategy that employs experimental phenotypic
manipulation of a female choice trait in an insect model
