Very easy even for people with only limited experience. Keep in well ventilated plastic containers (because of the preferred food plants, which dry out easily, netted cages are less recommended). Watch out for condensation when kept in plastic containers and do not give wet leaves. Fast growing on their preferred food. Ready to pupate in approximately six to seven weeks .
