The project "Survey of the Entomolo-gical Fauna in Paraná" (PROFAUPAR) was carried out in eight localities of Paraná, Brazil, during two years. In the first year a total of 1.607 specimens of Syrphidae were collected with Malaise trap. The species Toxomerus tibicen (Wiedemann, 1830), Microdon milis Curran, 1940 and Leucopodella gracilis (Williston, 1891) were the most abundant. The abundance and seasonality of each species are evaluated.
