Breeding Notes

  • an easy to breed species
  • incubation of the eggs on damp (not too wet) sand, with springtails to reduce mould growth
  • incubation time at room temperatures (20-23°C) is about 4 months
  • eggs of this species are very prone to get mouldy, and it is difficult to avoid this. Yet a thin mould layer does not affect the hatching ratio negatively
  • hatching ratio of my first generation was more than 70%
  • keep the nymphs in a cage with good ventilation and still high humidity, a constantly wet paper towel on the cage helps raising humidity
  • nymphs and adults can be kept in a Faunabox (or similar cage), according to their size
  • a ventilator in my phasmid room provides several times per day an air circulation and the cages are illuminated with strong light bulbs (HID)
  • move nymphs to a bigger cage as they grow bigger
  • I have never sprayed nymphs or adults with water
  • male will be adult after about 3,5 months (at room temperatures), females after about 4 months
  • females start to lay eggs after about 2 weeks, about 10 eggs per week
  • eggs are just dropped to the ground
