Breeding, Behaviour

• active mainly during the night
• eggs just drop to the ground
• about 15 - 20 eggs per female and week
• incubation (HH-method on slightly damp sand) about 4 months at 20 - 23 °C
• 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
• nymphs hatch in after dawn, in the early morning hours
• a humidity of about 60 - 70 % seems to be good enough for this species
• the Free-Standing-Setup is very much recommened for small nymphs
• this Phyllium Art should be kept in an airy cage (ventilator) too and get a lot of light
• one can spray them regularly with chlorine-free water, but the water should dry up again
• small and easy species
