(by Bruno Kneubuehler)


General Informations

  • provenience: Kirirom NP (Cambodia)
  • collected by Jérome Constant (Belgium) in late April 2015
  • taxonomic evaluation by Joachim Bresseel (Belgium) and Jerome Constant (Belgium)
  • F1 CB culture in Europe by Bruno Kneubuehler (2015)
  • further taxonomical informations ➤ phasmida.speciesfile.org
  • this is a pure culture, and serious breeders are asked to avoid mixing it with similar populations from a different provenience


  • slender, medium-sized
  • body length 9.5 - 11 cm
  • 2 small, forward-pointing spines on the head
  • light yellow eyes
  • brown, green-brown and greenish females

  • 3 x 1.5 mm
  • brown

Food Plants

  • bramble (Rubus spp.)
    well accepted by nymphs and adults

Breeding, Behaviour

  • active mainly during the night
  • they feign death when touched, or try to actively escape
  • eggs just drop to the ground
  • about 15 - 20 eggs per female and week
  • incubation (HH-method on slightly damp vermiculite) about 3 months at 20 - 23 °C
  • nymphs hatch during the night
  • a humidity of about 60 - 70 % RH seems to be good enough for this species
  • one can spray them regularly with chlorine-free water, but allow the water to dry up before spraying again
  • very easy to breed

Basics of phasmids breeding

  • keep only one species per cage, overpopulation is one of the main reasons for breeding failures
  • keep nymphs seperate from the adults, mainly to protect them during the crucial moulting phases
  • choose the cage big enough, when in doubt it is (usually) better to choose a cage too big than too small
  • a ventilator often supports good breeding results, as it seems to increase activity and feeding
  • provide enough light, but avoid direct sunlight (overheating)
  • try to keep day time temperatures below 25°C
  • a nocturnal fall of temperature is natural, and thus advantageous
  • do not spray too much, phasmids are no fish ! The water should dry up before you spray again
  • minimize disturbances - like loud music, commotions, light during the night, opening up cages in the early morning (main moulting phase for many species)
