General Notes

  • Paul Brock (1995) described this species orginally as Pinnispinus harmani
  • 2007 - first culture by Bruno Kneubuehler
  • 2010 - this species is not in culture at the moment

_________________

Origin

  • collected by Brigitte Lamprecht (Switzerland) in March 2007 close to Tanah Rata (Cameroon Highlands, Peninsular Malaysia)

_________________

Females

  • small phasmids
  • about 30 - 32 mm long
  • basic colour is a dark brown, with light brown areas and dots
  • big, upright spines on the upper thorax
  • spines on the upper abdomen get smaller from front to back
  • two big, bulging glands just behind the head (on the prothorax)

_________________

Males

  • very small phasmids
  • only about 18 - 21 mm long
  • basic colour is a dark brown, with light brown areas (like the head and abdomen)
  • very big, upright spines on the thorax and abdomen
  • two big, bulging glands just behind the head (on the prothorax)

_________________

Nymphs (L1)

  • very small, just 8 - 9 mm long
  • green in colour

_________________

Eggs

  • lentoid
  • about 2 x 2 mm
  • dark brown
  • glossy suface

_________________

Food Plants

  • they feed well on bramble (Rubus sp.)
  • adults also like raspberry (Rubus idaeus) very much

_________________

Defensive Behaviour

  • especially adults try to escape a potential threat by dropping to the ground and / or crawling away quickly
  • from their glands just behind the head, adults can secret a clear defensive liquid - which has a pungent smell
  • this defensive liquid is most probably irritating to mucous membranes and eyes. Therefore one should be cautious when handling this species
  • but they use this defensive liquide rarely

Breeding Notes

  • the culture of the first two generations was easy
  • but the hatching ratio of the 3. generation was very low, thus the culture died out
  • incubation of the eggs on damp (not wet !) sand, with springtails to reduce mould growth
  • incubation time at room temperatures (20 - 23°C) is about 4 months
  • keep nymphs and adults in a cage with good ventilation
  • nymphs and adults can be kept in a Faunabox (or similar cage)
  • take care that the humidity does not drop too low
  • a constantly wet paper towel on the bottom of the cage helps raising humidity
  • I have never sprayed nymphs or adults with water
  • make shure that nymphs, which are about to undergo the adult moult, do not find places in the cage which would not offer them enough room beneath to moult successfully
  • male will be adult after about 3,5 months (at room temperatures), females after 4 months
  • adult males are always on the back of a female (even a subadult female)
  • females start to lay eggs after about 2 -3 weeks
  • eggs are just dropped to the ground
