The urban green spaces (non-built-upareas) within urban environments are a fundamental element to the maintenance,and restoration of biodiversity. We described the diversity of saprophagousCalyptratae in three urban green spaces: a private garden, an urban park, and anatural reserve in Buenos Aires City, Argentina, and we compared the presenceof native and cosmopolite species. A total of 14,688 specimens were collected,representing 62 species. The three most abundant species, C. macellaria, T. (S.) occidua,and C. albiceps, represent 81.70 % ofthe total sample. 67.24 % of species collected were natives and presented anincrease in terms of richness towards less modified spaces. The richness ofcoprophilous species with the presence dog feces in public spaces arediscussed. Species cosmopolite treated as ?global homogenizers were identified.Muscoidea species were more sensible to the change produced by urbandevelopment on the natural ecosystems.
