Determination of female-biased sexual size dimorphism in moths with a variable instar number: The role of additional instars [PDF]

European Journal of Entomology, 2006
While the ultimate causes and adaptive significance of sexual size dimorphism (SSD) have been extensively studied, the developmental mechanisms behind this phenomenon have received little attention. Going through an additional larval instar may form a specific way of achieving SSD in arthropods. In the present study, the mechanisms of SSD determination
