Short description:

Friendly Hawker, Zosteraeschna minuscula, Genus Zosteraeschna, Family Aeshnidae is large sized, striped and speckled greenish yellow and brownish abdomen with distinct blue saddle at base of abdomen and distinctive dorsal stripes on thorax.

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.
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
Distribution and habitat:
  • Near endemic to South Africa. From Western Cape, through the high lying interior of South Africa.
  • Prefers small, open pools with an abundance of fringing reeds. Occasionally marshes and pools along fast flowing streams running through grassland. Mostly montane but occasionally at 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.
