Food Plants

  • bramble (Rubus spp.)
    well accepted by nymphs and adults
  • beech (Fagus sylvatica)
    well accepted by nymphs and adults

Breeding, Behaviour

  • very easy to breed
  • active mainly during the night
  • they feign death when touched
  • a defensive spray has not been observed
  • eggs just drop to the ground
  • about 5 - 10 eggs per female and week
  • incubation (Cup-Incubation-method, on medium damp vermiculite) about 3.5 - 4.5 months at 20 - 24 °C
  • eggs can be covered by vermiculite (about 5 mm high), which makes it easier for the nymphs to hatch without getting stuck in the eggs shell
  • eggs of this species are not prone to get mouldy
  • nymphs hatch during the night
  • a humidity of about 70 - 75 % 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
  • 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 ! The water should 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.)
