Muscidae occupy a great diversity of habitats and trophic niches. In temperate environments, the knowledgeof ecological aspects of saprophagous muscids is fragmentary. The aim of this work was to characterize the assemblagesof saprophagous muscids regarding their richness and abundance, bait preference, heliophily, and seasonality of speciesin three sites with different urbanization levels sampled during two years in an area of temperate Argentina. A totalof 3,321 specimens belonging to 20 species were collected. The baits and microhabitat preferences, and seasonalfluctuation of species were described. An increase in diversity in terms of evenness and richness in less urbanizedsites was observed. Results support the hypotheses about sites with an intermediate urbanization, which contain majorlandscape heterogeneity, show a higher number of species. The assemblage response regarding the environment typesreflects the adaptability to the physical changes along the three sites with different degree of urbanization.
