Gynandromorphism in the Odonata

In the Odonata, gynandromorphism has been rarely observed or mentioned in the literature. In 1929, Ris reported that only three cases were known to him. Two were in the Calopterygidae, and one in the Libellulidae. Since the gynandromorphic specimens have been recorded for one species of Aeshnidae and five more for the Libellulidae. For the latter family, I can add another record which is the first for the subfamily Corduliinae and the second for North America
