Segments 8 to 10 are azure blue on dorsum, with black basal annules.

Female is similar to the male; but the markings more greenish-blue or even yellow, except in very old specimens.

[6] It is larger and more slender insect than Caconeura gomphoides and breeding at a lower altitude.

The larger size, differently shaped pterostigma, the absence of a ventral spine on the base of the superior appendages, and the underside of the head entirely black, will help to distinguish it from Caconeura risi.

Commonly found perched on riparian vegetation along shaded streams.
