Food Plants

  • privet (Ligustrum spp.)
    well accepted by nymphs and adults
  • hazelnut (Corylus avellana)
    well accepted by nymphs and adults
  • beech (Fagus sylvatica)
    moderatly accepted by nymphs and adults

Breeding, Behaviour

  • easy to breed
  • active mainly during the night
  • they often behave very frantic when being touched and handled
  • a defensive spray has not been observed
  • eggs are stuck into filerwool (used in fish keeping), spread a layer of filter wool on the cage bottom
  • about 5 - 8 per female and week
  • incubation (Cup-Incubation-method, medium damp vermiculite) about 7 months at 20 - 24 °C (F1)
  • stick the eggs into the vermiculite, make sure the egg lid is up
  • eggs of this species are not prone to get mouldy
  • nymphs hatch during the night
  • 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 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 natural, and thus advantageous
  • 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.)
