Resumo: | The species of flies that visit flowers to feed were recorded, at the Ecological Station of the Federal University of Minas Gerais (UFMG). Asteraceae, Rhamnaceae, and Boraginaceae were the most visited families. Asteraceae was the richest family and the most visited by flies families and species. The highest diversity of visiting flies was on Baccharis trinervis (Lam.) (H'=1.86). The most diverse families of Diptera were Syrphidae (H'= 2.07) and Bombyliidae (H'= 1.52). The syrphids Ornidia obesa (L.) and Palpada furcata (Wied.) were the most abundant species amongst visitors. Despite the total abundance of Diptera was significantly higher in the rainy season, when a higher number of plants were blooming, there were more families of visitors during the dry season. The number of females in four families of flies was typically slightly higher than the number of males. Calliphoridae and Sarcophagidae showed similar patterns regarding the number of plant species visited, while Syrphidae were the most generalized, and Bombyliidae and Stratiomyidae visited few plant species. Many species of Diptera visit flowers, and their abundance on plants could indicate their importance as pollinators as well the importance of flowers for their diet.
