Fast. Caterpillars pupate within six to seven weeks when kept warm. Keep in well ventilated plastic containers, but watch out for condensation. In the final instar they require large amounts of leaves, this easily creates too moist conditions which can cause diseases. For that reason a netted cage might be better. In any case it is necessary to clean daily. The pupal stage is short.
