Whereas the forewings of this adult male Stream Glory are transparent, without any obvious colour, the colour of the upper hindwings is a stunning iridescent green with blackish wingtips, while the underside of the wings is dark brown.

This differs from females, who have pale brownish wings, with two small whitish spots at the upper edges of the forewings (fig.). This one was spotted near Mae Taeng in Chiang Mai.

Typical of damselflies is that when perching it rests its wings along and parallel to its abdomen, whereas the wings of dragonflies are held away from and perpendicular to the body when it rests (fig.).
