No evidence for contribution of sexually monomorphic wing pigmentation pattern to mate choice in <i>Drosophila guttifera</i>

In many animal groups, sexually dimorphic ornaments are thought to evolve by intraspecific competition or mate choice. Some researchers pointed out that monomorphic could also choice both sexes either sex. Many species of fruit fly have wing pigmentation. However, involvement their in has not been tested. We aimed examine whether the polka-dotted pattern on wings Drosophila guttifera contributes Because D. does dark condition at all and no courtship sound observed, some visual information is likely be used mating behaviour. compared number matings between individuals with without found presence influenced behaviour sexes. then bearing replaced wings, one group conspecific another heterospecific melanogaster pigmentation pattern. An effect conspecific/heterospecific was only detected females. Comparison wild-type black-painted revealed evidence a contribution
