Three types of biting flies form the bulk of the numbers: mosquitoes, black flies, and tabanidae, which include horse flies and deer flies. These three types of flies are discussed from their life cycle, to their habitat, to the nature of their bites and how they affect animals in general, humans in particular. The Canadian Department of Agriculture, with the Defense Research Board, has been doing research on these types of flies since 1947 in order to develop repellents and insecticides, with the research into the latter including how to apply them to their best effect under differing environmental conditions.
