(by Bruno Kneubuehler)


General Informations

  • provenience: Bidoup Nui Ba NP (Vietnam)
  • collected 2014 by Joachim Bresseel (Belgium) and Jérome Constant (Belgium)
  • taxonomic evaluation by Joachim Bresseel (Belgium)
  • F1 CB culture by Bruno Kneubuehler (2014 / 2015)
  • further taxonomical informations ➤
  • this is a pure culture, and serious breeders will avoid mixing it with cultures of a different provenience


  • medium sized Phyllium species
  • body length 8 - 8.5 cm
  • green
  • some females have reddish-brown patches and lines


  • body length 6 - 6.5 cm
  • light green


  • coloration of these nymphs are distinctively different from nymphs of other Phyllium species
  • 16 mm
  • freshly hatched nymphs are dark brown (legs, head, pro- and mesothorax) and red (metathorax, abdomen)
  • on how to easily distinguish between male and female nymphs


  • 5 x 3 mm
  • brown
  • suface looks furry

Food Plants

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

Breeding, Behaviour

  • active mainly during the night
  • they feign death when touched
  • adult males drop to the ground quickly, when they feel threatened
  • eggs just drop to the ground
  • about 10 - 15 eggs per female and week
  • incubation (HH-method on slightly damp sand) about 3.5 - 4.5 months at 20 - 23 °C
  • eggs of this species are very prone to get mouldy (like eggs of many Phyllium species), and it is difficult to avoid this. Yet a thin mould layer does not affect the hatching ratio negatively
  • nymphs hatch during the night
  • a humidity of about 60 - 70 % seems to be good enough for this species
  • the Free-Standing-Setup is very much recommened for small nymphs
  • this Phyllium species should be kept in an airy cage (ventilator) too and get a lot of light
  • one can spray them regularly with chlorine-free water, but the water should dry up again
  • easy to breed in my experience

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
  • choose the cage big enough, and when in doubt it is (usually) better to choose a bigger cage than a too small one
  • a ventilator often supports good breeding results
  • provide enough light, but avoid direct sunlight (overheating)
  • try to keep temperatures below 25°C
  • a nocturnal fall of temperature is healty for the phasmids
  • do not spray too much, phasmids are no fish ! The spray should dry up before you spray again
  • minimize disturbances (loud music, commotions, light at or during the night, ect.) minimal
