The complex nature of urban environments can have different effects on speciesdiversity and composition. The aim of this work was to characterize the assemblageof Calliphoridae regarding its richness, abundance, and synanthropy in CórdobaCity, Argentina. Three sampling sites differing in their distance to the border of thecity and degree of urbanization were selected. In each site, collections were carriedout with 12 traps baited with cow liver (200 g per trap) that were operated for fiveconsecutive days during three different times of the year, in April, June and August2013. A total of 341 adult calliphorids from nine species, Lucilia sericata (Meigen), L.eximia (Wiedemann), L. cuprina (Wiedemann), L. cluvia (Walker), Calliphora vicinaRobineau-Desvoidy, Sarconesia chlorogaster (Wiedemann), Chrysomya albiceps(Wiedemann), C. megacephala (Fabricius) and C. chloropyga (Wiedemann) werecollected. Lucilia sericata was the most abundant species followed by C. vicina.Species diversity, composition and abundance changed between sites, richness beinglowest at the most urbanized site. All species are cosmopolitan except Sarconesiachlorogaster, whose distribution is restricted to South America. These results areconsistent with a homogenization of the fauna in urban environments.
