The heel flies or ox-warble flies and their larvae, commonly called cattle grubs or warbles, are among the most troublesome and costly insect pests of livestock producers in South Dakota. These parasites attack cattle almost exclusively although they may occur at times in other domestic and in wild animals. Infestations in man have been recorded, but these cases are quite rare. This work deals only with the occurrence of the parasites in cattle.
