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
• 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
