Key identification features:

Male:

  • Recognised by the distinctive dorsal stripes on the thorax. Straight and parallel, light green in colour.
  • There is a clear anchor shaped mark on the forehead.
  • Abdomen is mostly dark brown with pairs of yellowish green spots dorsally, and double, light-blue spots on side. In side view, S1 and S2 have a yellow, lateral stripe which runs into a bright blue lateral patch on S3. From above, S2 has a short, longitudinal yellow stripe leading into a dorsal, cobalt blue patch

Female:

  • Greener than male’s yellowish green, more reddish than male’s dark brown, wings smokier and sometimes dark brown in young females
  • Abdomen without blue and with fewer spots on first few segments.
Habitat:
  • Standing waters and (head water) streams in open landscapes, open areas in forest or shaded by gallery forest. Often pools in stream beds with emergent and aquatic vegetation, coarse detritus, and/or probably overhanging branches.
  • From 100 to 2100 m above sea level, but possibly down to sea level.
Behaviour:
  • Hawks slowly up and down along margins of pools, inquisitive often approaching closely, when its colour and pattern can be easily seen. Does not seem to be disturbed easily.
Compared with other species:
  • Z. minuscula as more brownish and not as green as Pinheyschna subpupillata and prefers pools rather than streams as does P. subpupillata
  • The blue abdominal saddle is visible in flight but is not as big as in Anax ephippiger.
  • The two distinctive features of Z. minuscula are the narrow (1 mm wide), yellow, parallel stripes on front of thorax, and the anchor-like, black marking on upper surface of frons.
  • In Z. usambarica the dorsal stripes are light green, wedge shaped and the frons above has a pentagonal-like, black marking.
  • Z usambarica also have a blue saddle but larger than Z minuscula
