Difficulties experienced in rearing Feralia spp. beyond the pupal stage, and inability to distinguish species in the immature forms, has led to a study of their larvae and pupae. So far no specific differences have been observed in the larvae but progress has been made in the identification of Feralia in the pupal stage.
