General Informations

  • provenience: near Pakung Jae (south slopes of hills about 25 km north of Negara, Jembrana, western Bali)
  • collected in June 2012 by B. de Groof (ID)
  • ID by Frank Hennemann (DE)
  • F1 CB culture in 2013 by Bruno Kneubuehler (CH)
  • further taxonomical informations ➤ Phasmida Species Files
  • this is a pure culture, and serious breeders are requested to avoid mixing this culture with similar populations from a different provenience. When spreading this culture to other breeders, then always use the full name with provenience
  • this culture has the number CLP 620  (Online Phasma Culture List)


  • small, colorful, winged phasmids
  • body length ≈ 6 cm
  • female coloration does not vary
  • mainly green with blue and yellow areas
  • abdomen under the wings is brightly orange
  • membranous part of hindwings is black


  • slim, small, colorful phasmids
  • body length ≈ 4.5 cm
  • male coloration does not vary
  • coloration very similar to the females


  • freshly hatched nymphs are red and look quite hairy
  • by L4 it is quite easy to distinguish between male and female nymphs
  • on how to distinguish between male and female nymphs


  • 3.5 x 2 mm
  • brown, matt

Food Plants

  • beech (Fagus sylvatica)
    well accepted by nymphs and adults
  • use the apple-slice-trick for freshly hatched nymphs, until they have started to feed well
  • one can also use an apple-coating on the beech (Fagus sylvatica) leaves to coax freshly hatched nymphs to start feeding
  • unidentified willow (maybe Salix triandra ?)
    well accepted by older nymphs and adults
  • this culture has been collected very close to a peanut plantation, thus peanut (Arachis hypogaea) might even be another food plant

Breeding, Behaviour

  • easy to breed, if their food plant is availabl
  • active mainly during the night, but adult males are active during the day sometimes
  • usually they behave very frantic when being touched and handled
  • a defensive spray has been observed
  • eggs are glued to twigs, leaves, side of the cage but never to the ground
  • a clutch per female every 2 weeks
  • about 5 - 10 eggs per clutch
  • GET method for a natural incubation of glued eggs
  • incubation about 3 months at 20 - 24 °C
  • incubation time can be extended with the LTD-Method (up to at least 3 months), as their food plant (beech) is not available during european winter time
  • eggs of this species are not prone to get mouldy, especially not when incubated with the GET-method
  • nymphs hatch during daytime (early morning)
  • it is quite common that some phasmid nymphs hatch weeks after the first nymphs - from the same batch of eggs
  • a humidity of about 65 - 75 % rH seems to be good enough for nymphs and adults
  • one can spray them regularly with chlorine-free water, but allow the water to dry up before spraying again
  • small nymphs can be kept in a Faunabox (or a similar cage), which shall not be too small
  • provide a cage of about 30 x 30 x 30 (cm, L x B x H) for 3 - 4 adult couples
  • males will be adult after 3 months (at 20 - 24°C), females after 3.5 - 4 months

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, mainly to protect them during the crucial moulting phases
  • choose the cage big enough. When in doubt, too big is (usually) better than too small
  • a ventilator often supports good breeding results, as it seems to increase activity and feeding
  • provide enough light, but avoid direct sunlight (overheating)
  • try to keep day time temperatures below 25°C
  • a nocturnal fall of temperature is very natural (down to around 20°C)
  • do not spray too much, phasmids are no fish ! Allow the water to dry up before you spray again
  • minimize disturbances (loud music, commotions, light at or during the night, opening up cages in the morning [often a moulting phase] ect.)
