  • further taxonomical informations ➤
  • this is a pure culture, and serious breeders are asked 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


  • gracile, slender, small species
  • body length 6 - 6.5 cm
  • WC females were green, CB females are mostly brown

  • 2 x 1.5 mm
  • brown or grey-brown
  • strongly structured surface

Food Plants

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

Breeding, Behaviour

  • very easy to breed
  • active mainly during the night
  • they can behave very hectic when being touched, trying to escape running away
  • eggs just drop to the ground
  • about 15 - 20 eggs per female and week
  • incubation (Cup-Incubation-method with medium damp vermiculite) about 5 - 8 weeks at 20 - 23 °C
  • eggs can be covered by Vermiculite (about 3 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 % seems to be good enough for this species, but can also be higher
  • males and females will be adult after 3 months (at 20 - 24°C)
  • one can spray them regularly with chlorine-free water, but allow the water to dry up before spraying again

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.)
