Thorntails

Family Gomphidae      Rambur, 1842

Africa
  • Two species in Africa 
    • Cape Thorntail . C. triceraticus is confined to the southern Cape area of South Africa
    • Common Thorntail C. pictus in countries mostly south of the equator
General description:
  • Medium-sized (hindwing 28-30 mm) dragonfly with milky thorax bands and yellow costa contrasting with black pterostigma that recall Crenigomphus, but the modified abdominal segment 10, foliation on segment 8 only and distinct anal loop suggest Phyllogomphus is the genus’ nearest relative.
Habitat and behaviour
  • Both species inhabit open and calm pool-like sections of streams and rivers, and often perch on the ground or rocks.
  • C. picta also easily colonises a body of water confined within an enclosure, as a reservoir, which is unusual for gomphids (Clubtails).
