General Informations

  • originally described by Bi & Li (1994) as Datames guangxiensis
  • synonyms: Dares guangxiensis (Zompro, 2004)
  • only females are known from nature and all captive bred cultures are parthenogenetic too
  • 2009 - first time cultured by Bruno Kneubuehler
  • 2010 - distributed as Pylaemenes guangxiensis "Taiwan"



  • my culture stock has been collected in North Taiwan in 2008
  • identification by Yamai S. Huang (Taiwan)



  • sturdy insects - about 5 cm long
  • very nice bark-like structure and colouration from different shades of brown
  • antennae are shorter than the fore legs



  • nymphs accept bramble (Rubus sp.) easily, but adults refuse to feed on it
  • nymphs and adults like cherry laurel (Prunus laurocerasus), a very common and evergreen garden plant
  • nymphs and adults like Salal (Gaultheria shallon)
  • other sources also mention the following foodplants: oak (Quercus sp.), rose (Rosa sp.), Epipremnum (E. aureum) and beech (Fagus sp.)



  • especially small nymphs often hide during the day along the edge of a leave. And here they are in danger of being bitten by adults, which start to feed from the edge of the leaves !
  • therefore it is better to seperate small nymphs and adult specimens


Breeding Notes

  • an easy to breed species
  • incubation on damp sand (not too wet!), with spring tails to reduce mould growth
  • incubation duration at room temperatures (20-23°C)  is about 4 - 6 months
  • hatching ratio is low, only about 10 - 15 % in my culture....
  • after hatching the nymphs remain inactive for quite some time - it can take up to two week before they will start to feed
  • they grow up in a Faunabox (or similar cage) very nicely - also adults can be kept in such a small cage
  • I do never spray them with water - a constantly wet paper towel on the cage floor provids enough humidity
  • it is advisable to cover the container in which the food plants stand with cotton wool - to prevent the nymphs from drowning
  • nymphs as well as adults will feign death when being touched or handled - a very handy species
  • it takes a long time for the females to mature - up to 15 months
  • about 6 weeks after the final moult they will start to lay eggs
  • about 1-3 eggs per week
  • they prefer to lay the eggs in a damp place
