Key identification features:
Male:
- Face greenish with heavy white pruinescence. Labrum green or greenish blue with three basal black spots, edged with black. Cheeks lime green. Anteclypeus green to greenish blue. Head black above, heavily pruinescent in front. Postocular spots large, roundish, bright blue. Neck brown
- Eyes black above, lime green below. Neck dark slate blue above with greenish sides that become pruinescent.
- Thorax extensively black to dark slate blue, usually with distinct (sometimes pruinose) antihumeral stripes. When young the antihumeral stripe is well defined linking to the interpleural stipe following the hind margin of the thorax The interpleural stripe links with the metapleural stripe with a well defined stripe at the hindmargin of the thorax . The metapleural strip may continue to the front margin of the thorax This well defined stripes become less well defined with age Sides light green. Legs usually, at least, broadly marked with black. Brown between wings.
- Wings clear. with dark brown to black veins, brownish when young.. Pterostigma bright reddish brown.
- Abdomen dark slate blue above, greyish blue below, becoming heavily whitish pruinescent with age. Young males has distinct blue pattern on s 7- 10 (slightly reminiscent of the pattern displayed on the female S8 -10) becoming dark blue and (may) disappearing with age. Cerci short, only slightly longer than paraprocts (lateral view), lower branch only slightly longer than upper, gap between them mere notch or slit, flange of lower branch usually rather prominent and oblique relative to main axis of cercus (dorsal view). Paraprocts pointed and up-turned. Brown in dorsal view. Brown between cerci in dorsal view.
Female:
- Striking, light sky blue and black with distinct round blue postocular spots. Transitioning from a light brown to blue with age.
- Abdomen blackish, almost dark metallic green above, greenish below. Light brown when young Segments 8 - 10 bright blue above with distinct patterns on S 8 - 10 When young the patterns are brown transitioning from s10 to s 5 to blue. This pattern may darken to light blue with age
Habitat:
- Mostly species of open or montane habitats, streams, but also rivers, in open landscapes, but sometimes shaded by gallery forest. Usually with emergent vegetation and often rocks and a gravelly bottom clear mountain streams, probably especially calmer (like pools) and faster sections (rapids, falls).
- From 0 to 2900 m above sea level, but mostly between 900 and 2000.
Behaviour:
- Perches on the grasses surrounding flowing rocky stream where it is actively hunting therefore easily seen. Females often seen with males. Perch horizontally close to the water.
Compared with other species:
- When mature, it is very distinctive being all dark slate blue with an all pruinescent whitish, powdery covering.
- Powder face marking can be confused with Powder-faced Sprite P. kersteni, Mountain Sprite P. draconis (cohabit)
- Young easily confused with Slate Sprite Pseudagrion salisburyense, as both have roundish blue postocular spots and blue abdominal tips.
- Brown Pterostigmas. Springwater Sprite P caffrum distinct reddish brown
- Female abdominal segment 8 - 10 similar to female Palmiet Sprite, P, furcigerum
- Pterostigmas also lighter and distinctly reddish P. spernatumin whereas they are darker, duller and more blackish in P. salisburyense.
