southern China at higher elevations
around 9 centimeter (in captivity often smaller due to inbred)
emergence is irregular, usually triggered by cool and humid weather
Pinus (including Pinus sylvestris)
In general not difficult, but some experience is required. Keep cool (in between 15 and 24°C) in well ventilated plastic containers (just watch out for condensation). A good alternative way to rear them is on a small, potted pine in a netted cage. Ready to pupate within 6 to 7 weeks. Keep the cocoons in a cool, unheated room. Emergence of the adults is triggered by a higher ambient air humidity and can be somewhat irregular.
avoid too much fluctuation in temperature and/or humidity
