General Notes

  • 2010 - first successful culture of this species by Thierry Heitzmann (Philippines)
  • 2011 - this species is currently being examined taxonomically by Joachim Bresseel (Belgium)



  • collected by Thierry Heitzmann (Philippines) on Pulog Mountain (Pocdol mountain range, Sorsogon, Bicol Province, Südost-Luzon, Philippines) in September and October 2010



  • sturdy and spiny phasmids
  • 9.5 - 10 cm long
  • many spines on the body and the legs
  • varied coloration amongst females - dark brown, greyish-brown to light brown with greenish areas
  • antennae longer than the fore legs
  • no wings



  • 6 - 6.5 cm long
  • several larger spines on the body
  • many small spines on the legs
  • brown head, thorax and legs
  • greenish-brown (dorsally) and light-brown (ventrally) abdomen
  • some males do have a light brown stripe on their back
  • antennae considerably longer than the fore legs
  • no wings



  • about 19 mm (L1)
  • coloration varies amongst nymphs - different shades of brown
  • older nymphs appear to be more spinous than adults
  • differentiation between males and females is possible in L1
  • by L3, female nymphs have a clear prolongation at the abdominal ending (dorsally)



  • about 5 x 4 mm
  • grey
  • black lid (operculum)
  • many small pores
  • irregularely shaped
  • matt


Food Plants

  • nymphs as well as adults feed easily on bramble (Rubus sp.)



  • nymphs and adults just feign death when being threatened
  • males will be adult after about 4months (at 20 - 23°C), females after about 4 - 5 months
  • females start laying eggs after about 3 - 4 weeks
  • eggs are being stuck into the ground
  • a sand-filled (at least 4 cm high dry sand) rectangular box in a corner (!) of the cage is accepted as substrate where they bury their eggs. Thus the eggs can be sieved out easily
  • about 5 eggs per week and female
  • mating are frequent and to not last for long


Breeding Notes

  • a very easy to keep and nice species
  • incubation with the HH-incubation method (on slightly damp sand) yields good hatching ratios
  • spread some dry moss over the eggs, this will make it much easier for the nymphs to hatch properly
  • incubation time (at room temperature) is about 4 - 4.5 months
  • keep the nymphs in a cage with good ventilation
  • take care that the humidity does not drop too low
  • a constantly wet paper towel on the floor of the cage helps raising humidity
  • nymphs and adults can be kept in a Faunabox (or similar cages)
  • if necessary move nymphs to a bigger cage as they grow bigger
  • I have never sprayed nymphs or adults with water
  • make shure that nymphs, which are about to undergo their adult moult, do not find places in the cage which would not offer them enough space beneath to moult successfully
