Clitarchus

This genus is perhaps the most common stick insect in New Zealand. It is very common on kanuka and manuka throughout the North Island and part of the South Island. These species are usually green, but can often be various shades of brown or even red. Some individuals have many tubercles on the body surface. There are two recognized species in the genus:

  • Clitarchus hookeri (White 1846)
  • Clitarchus tuberculatus Salmon 1991

These two species are not able to reliably differentiated using current descriptions and a revision of the genus is in progress. Two new species are known from northern New Zealand (Buckley et al. 2010a). Some populations of this species contain only females and so must reproduce via parthenogenesis (Buckley et al. 2008, 2010a; Morgan-Richards et al. 2010).
