General Informations

  • provenience: Sukabumi (western Java, close to Mt. Halimun)
  • collected by Garda Bagus Damastra
  • taxonomic evaluation by Joachim Bresseel (Belgium)
  • F1 CB culture by Bruno Kneubuehler (2014)
  • further taxonomical informations ➤
  • this is a pure culture, and serious breeders will not mix it with cultures of a different provenience


  • medium sized species
  • 8 - 9 cm
  • most females are dark green
  • some females turn out yellow-brown
  • sometimes with brown pattern
  • lobes at the end of the abdomen more or less pronouced
  • short hind wings
  • no specific coxae color


  • 5.5 - 6.5 cm
  • after the final moult, most males are green, but they turn yellowish-brown after  2 - 3 weeks
  • broad abdomen

Food Plants

  • Salal (Gaultheira shallon)
    well accepted by nymphs and adults
  • hazelnut (Corylus avellana)
    well accepted by older nymphs and adults
  • bramble (Rubus spp.)
    other breeders report that bramble is also accepted   (info Jannick Roser)
  • strawberry leaves (Fragaria) might also be well accepted by small nymphs, as it is the case in Phyllium bioculatum "Tapah". But this has not been tested...
  • english oak (Quercus robur)
    well accepted     (info Robbie Emberson)

Breeding, Behaviour

  • active mainly during the night
  • though sometimes males are also active during the day
  • females try to drop to the gound when they feel threatened, or they just feign death
  • males often try to escape a potential predator by quickly crawling away
  • males can also fly very well, though they do so rather seldomly
  • eggs just drop to the ground
  • about 10 eggs per female and week
  • incubation (HH-method on slightly damp sand) about 4 months at 20 - 23 °C
  • eggs of this species are very prone to get mouldy, and it is difficult to avoid this. Yet a thin mould layer does not affect the hatching ratio negatively
  • nymphs hatch after dawn, often around noon
  • 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
  • despite the food plant requirements, this species is easy to breed
