  • Young individuals bright metallic green, darkening to dull metallic green with age then becomes bright shiny copper colour at very old age
  • Face bright metallic green with strong central yellow band.
  • Eyes greyish above, light greenish grey below, darkening with age.
  • Mid dorsal carina black, dorsal stripe dark metallic green to copper green.  Antihumeral stripe narrow yellow broadening to continuing into neck but not to the wing base.  Humeral stripe metallic green with broad yellow stripe bellow. Lower thorax blue/grey. Thoraxes of young individuals bright metallic green, outlined bright yellow from above; sides with bright yellow stripes; dull dark green in northern populations

  • Mostly along rivers and streams or headwaters, in open landscapes, open areas in forest or shaded by gallery forest. Often calmer sections (like pools) with emergent vegetation, coarse detritus, rocks and/or a soft (like muddy) bottom. From 0 to 2400 m above sea level, but mostly between 1100 and 2100.
