This paper made an account on the morphology,biology and large-scale breeding of Danaus chtysippus chrysippus(Linnaeus) at adult and larvae stages.Danaus chrysippus chrysippus(Linnaeus) occurs all over the year in Hainan Jingfengling region with overlapping generations about 15.They require 29~37 days to complete a generation in winter and 14～18 days in summer.The adults are highly stress resistance under natural enemy and bad environments,especially high temperature.Asclepias curassavica L.and Calotropis gigantean(L.) are their host plants.For their colorful and graceful outside,they can be set flying in butterfly gardens and in celebrated occasions.Good ecological environment is the key to success of large～scale breeding,and the rearing of larvae is the important part of large-scale breeding.The females lay their eggs separately.Larvae have 5 instars,and the newly hatched larvae should be fed outdoor in net bag,while the late fifth instars should be fed indoor in plastic basins,and they will pupation under the covers of plastic basin.The covers should be hung in the emergence room with temperature controlled at 25～28℃and humidity at 60～80%by air-conditioner and spray device,so that the pupas can grow and eclosion normally.
