Small Red-eyed Damselfly

The species is a small damselfly, about 29 millimetres (1.1 in) long, predominantly black with iridescent blue markings. Its large, spaced eyes are a deep red. Like the red-eyed damselfly, both sexes lack pale spots behind the eyes and have pale brown pterostigmata. The male has a bronze-black top and blue sides. The sides of the female's thorax are yellow, green or blue. The rear edge of the pronotum is rounded. Viewed from the side, the second and eighth segment of the abdomen of the male are mostly blue, which distinguishes it from the red-eyed damselfly where these are mostly black.

Mating occurs either on floating plants or at the margins. When perched on floating plants, the male holds its abdomen slightly upcurved (the red-eyed damselfly holds it straight).
