A Preliminary Study of Sexual Dimorphism in Wing Morphology of Five Species of the Flying Lizards, Genus Draco

Abstract

Sexual size dimorphism was examined for five species of flying lizards, genus Draco, from Southeast Asia. Female SVL was larger than male SVL in three species. This sexual size dimorphism may be related to differences in gliding performance between males and females. Quantitative characters of wings such as wing shape and wing loading were compared between the sexes within each species. Significant sexual dimorphism was found in five characters.
