The annual theridiid spider Enoplognatha ovata exhibits a genetically based color polymorphism of red and nonred phenotypes. We evaluated fitness differences between red and nonred spiders by manipulating morph frequencies in a population in which red morphs were rare (≤5%). Broods from red females were introduced to open experimental plots from which… CONTINUE READING
