The aim of the present study was to explore thediversity and describe the spatial distribution of Calliphoridae andSarcophagidae along an urbanization gradient in the Iberá Wetlands. The flieswere collected at 18 sampling points, three per site. In total 3,318 flies werecollected (3,077 blow flies and 241 flesh flies), distributed in 13 genera and33 species. Calliphoridae was the most abundant, comprised 92.74% of all adultflies. Chrysomya albiceps (Wiedeman),Cochliomyia macellaria (F.), Ch. megacephala (F.) and Ch. putoria (Wiedemann 1830) were themost abundant species representing 82.21% of the total sample. The genus Oxysarcodexia Townsend was the mostdiverse with 10 species represented. The abundance of exotic species represents62.85% of the total sample, showing a reduction towards less disturbed sites.The results of this study indicated that sites with intermediate impact hadhigher diversity than those where the disturbances are high or absent. Our findingsprovide the first assessment of Calliphoridae and Sarcophagidae diversity inthe area of the Iberá Wetlands.
