Over a period of one year (May, 1980 to April, 1981), systematic collections of Sarcophagidae were made in three ecologically distinct areas of Belo Horizonte, Minas Gerais. Two types of traps and five types of bait were used: raw fish, carcasses of mice, viscera of chickens, banana mashed with sugar, and human faeces. Of the total of 10,097 specimens captured, the 9,582 studied included 25 species. Indices of synanthropy (I.S.) for the 25 species varied considerably. The most synanthropic were Parasarcophaga ruficornis (I.S. = + 94.7) and Bercaea haemorrhoidalis (I.S. = + 84.3), and the least were Euboettcheria florencioi (I.S. = - 98.8) and Oxysarcodexia augusta (I.S. = - 96.9).
