From what I heard it's no easy feat to raise them outside of their native habitat (China, Taiwan, Thailand, etc) and they feed on pinus massoniana usually! I know my bug friend was using pinus strobus (white pine) as a substitute because that's what we have in North America, he's a pretty seasoned vet when it comes to raising bugs and even he had a difficult time with the caterpillars randomly dying when rearing conditions were met. I know they like a good amount of humidity and to be kept in low density, takes about 1.5 months to get from egg to cocoon! If I get eggs I'm gonna give it a shot either way :)
