Horse flies of the genus Tabanus are among the most persistent and annoying of the blood-sucking pests affecting Utah livestock. Tn many areas of this state they are particularly troublesome to cattle and horses during much of the summer and fall. The intermittent feeding habits of the Tabanidae at once mark them as potential vectors of disease. This study has been undertaken as a part of the investigation of the role of blood-sucking insects in the transmission of equine encephalomyelitis.
