Tabanid flies in blood-sucking activity were captured by CO_2-lured mosquito-net traps which were set at 6 sampling sites along the basin of the Horobetsu River at the horse-breeding center of Hidaka District in Hokkaido for 2 days in the early August of 1976. In total 2,726 female flies of 16 species were captured in the area with a marked predominancy of Tabanus nipponicus and T. chrysurus. Number of species and flies were more numerous in the upstream to midstream than in the downstream, though number of flies greatly fluctuated among the sites. T. chrysurus and Haematopota tristis were most abundant in the upstream where forestlands spread, but T. nipponicus and T. trigonus were predominantly abundant in the midstream to downstream where pasturelands developed. The abundance of flies was not directly related to the richness of blood-sources in this region, but rather depended on the existence of larval habitats in each sampling site.
