Abstract
Neurothemis tullia tullia (Drury) is a common dragonfly which occurs in large colonies in swamps and heavily- weeded tanks in different parts of India. It exhibits striking sexual dimorphism in colour and wing spot patterns. The male is dark with a large blue-black spot on the wing base while the female is dull olivaceous and the wing base is amber yellow. The sexes can be easily identified from quite a far distance. Andromorphic females are very rarely found in anisopteran dragonflies. This paper describes and compares not only the coloration and wing spots of the normal male and female with this andromorphic female but also reports about its sexual fitness to produce viable eggs.
