Erythromma najas (Hansemann, 1823)

Erythromma najas, the red-eyed damselfly, is a member of the Coenagrionidae family of damselflies.

The species is a small damselfly, 35 millimetres (1.4 in) long, predominantly black with iridescent blue markings. The male resembles blue-tailed damselflies (Ischnura species) but is distinguished by its large, spaced eyes that are a deep red. It is very similar to the small red-eyed damselfly (Erythromma viridulum).
