Abstract
In the prairie region of Western Canada certain species of bumble bees are the principal pollinators of red clover, Trifolium pratense L. (Hobbs, 1957). Certain bumble and leaf-cutter bees are the only effective pollinators of alfalfa, Medicago sativa L., in Western Canada (Hobbs and Lilly, 1954; Hobbs, 1956; Peck and Bolton, 1946; Stephen, 1955). Unfortunately, bumble and leaf-cutter bees are seldom very abundant.
