Here we report a case of gynandromorphism in the dragonfly Crocothemis servilia (Drury, 1773), (Insecta: Odonata: Anisoptera: Libellulidae) from the Puzhakkal region of Kole wetlands, Thrissur, Kerala, southern India from a single photograph recorded during a survey conducted on 14 July 2019.  The individual exhibits bilateral gynandromorphism only in the thoracic region, half of which showed blood red colouration as in males and the other half pale yellow characteristic of females.  The base of the wing of the red half was marked with rich amber, in contrast with the other wing base which was paler.  The head, legs, and abdomen showed typical female morphology.
