Calliphora quadrimaculata, commonly known as the New Zealand blue blowfly and by its Maori name Rango Pango, is an insect in order Diptera of Calliphoridae family in the genus Calliphora. This particular blowfly is found throughout New Zealand as well as on Chatham, Auckland, Stewart and Campbell Islands that surround New Zealand. Generally blowfly maggots in New Zealand have to feed on animal tissue or faeces to develop into adult blowflies. However the New Zealand blue blowfly larvae can survive on decaying leaves of snow tussock in alpine regions and reach adult maturity without feeding on any animal tissue.
