A Comparison of Wing Shape and Size in Andromorph and Gynomorph Females with Males of Calopteryx Intermedia Using Geometric Morphometrics [PDF]
Female polymorphism is visible in some populations of Odonata species for unknown reasons. In general, one of the female forms which is more or less similar to males is called andromorph. Andromorph females show similar color patterns and sometimes, even
