T HE study of insects of northern Canada has in the past depended mainly on a very small number of collections, some obtained on early expeditions searching for the Northwest Passage, and others taken incidentally on subse-quent expeditions. The work of Kirby ( 1 8 3 7) , the reports of the Canadian Arctic expedition (Hewitt, 1 9 2 2) and of the Fifth Thule expedition (Henrik-sen, 1 9 3 7) , and a few short papers represent the main contributions for many years. Organized entomological research in northern Canada began in 1 9 4 7 as a joint project of the Defence Research Board, Department of National Defence, and the Entomology and the Botany and Plant Pathology divisions, Department of Agriculture. The research program was divided into three major phases as follows: ( 1) investigations on life-history, habits, ecology, and control of biting flies by the Veterinary and Medical Entomology Unit; ( 2) the Northern Insect Survey, which deals with systematics, distribution, relative abundance; and ecology of biting flies and other insects, by the Systematic Entomology and Botany units; and ( 3) investigations on laboratory rearing techniques for
