The seasonal distribution and relative abundance of adult Tabanidae were studied in 2 mining communities of western Labrador during 1984. Four collecting methods were compared. Fifteen species belonging to 2 genera were collected (6 Chrysops and 9 Hybomitra). Results were compared with other studies conducted in adjacent northern areas. Chrysops excitans was the most abundant species collected. The horizontal distribution of adult host-seeking C. excitans was investigated. A list of species collected in previous years and in central Labrador is also given.
