  • on how to distinguish between male and female nymphs


  • 3 x 1.5 mm
  • brown

Food Plants

  • hypericum (Hypericum)
    very well accepted by nymphs and adults

Breeding, Behaviour

  • very easy to breed
  • active mainly during the night
  • they ususally feign death when touched
  • but adult males and females can fly very well
  • a defensive spray has not been observed
  • eggs are glued in rows to different objects (leaves, twigs, containers, cage)
  • if eggs have to be removed, then spray them generously with water. And after about 10 minutes they can be removed carefully
  • about clutch every 2 - 3 weeks, with 10 - 15 eggs per clutch
  • GET method for a natural incubation of glued eggs
  • incubation about 4 - 5 weeks at 20 - 24 °C
  • eggs of this species are not prone to get mouldy
  • nymphs hatch during daytime (around noon)
  • a humidity of about 65 - 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 2 months (at 20 - 24°C), females after 3 months
  • incubation time can be extended with the LTD-Method, as their food plants are not easily available during european winter time

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.)
