Different in appearance from all other Malachite species
- Inhabits clear montane streams and rivers with clear pools that are strewn with very large lichen-covered boulders, but sometimes headwaters, in open landscapes, but possibly also in shade of gallery forest. Often with emergent vegetation, coarse detritus, rocks and a soft (like muddy) bottom, probably especially calmer sections (like pools).
- Inferred to occur from 0 to 1000 m above sea level, but possibly up to 1600.
- Settles with wings spread on exposed rocky surfaces.
- Both the male and female rest on the tops of the massive and well-weathered boulders where they are camouflaged among lichens.
- Occasionally the male can also be seen perching on twigs over the stream.
- Sometimes seen on the wing in December and January, but it is usually a late season species, being most abundant in April and May.
- Hangs in shaded clefts with wings folded when hot.
