An inventory of the Agromyzidae (Diptera) of Canadian tallgrass prairies was conducted in southern Manitoba. Specimens were collected at primary study sites between 1996--2000, by sweeping, malaise traps and pan traps. In order to establish species distributions in eastern grasslands, Agromyzidae were also obtained from other surveys in southern Ontario grasslands. Over 850 specimens were identified from 49 species (15 genera) from the Manitoba sites. The most diverse genera were Liriomyza (10 species) and Cerodontha (8 species), and the latter genus was the most abundant, primarily because of two dominant species: C. superciliosa and C. inconspicua. The zoogeographic distribution of tallgrass prairie agromyzids is dominated by Nearctic and Holarctic species, suggesting that many of the species are generalists. Species shared with eastern grasslands are primarily widespread Nearctic species. Twenty-eight percent of the species show grassland affinities; further investigation is required to confirm the distribution and habitat preference of these species.
