A total of 301 bats, sent by municipal authorities or captured by CCZ and the Núcleos Regionais de Zoonoses de São Paulo, were examined by specialists from the CCZ and the Núcleos Regionais de Zoonoses de São Paulo. Twenty-four species, belonging to four families were collected: Molossidae (71,4%), Phyllostomidae (23,6%), Vespertilionidae (4,7%) and Noctilionidae (0,3%). Aerial insectivorous bats (Molossidae and Vespertilionidae) were the majority, representing 76,1% of the total. The presence of aerial insectivorous bats in the met- ropolitan region of São Paulo can be explained by the wide availability of structures offering suitable roosting conditions, primarily the heat-expansion walls in large buildings (capable of housing major colonies), and year-round food supplies (urban street lights func- tion as light-trap for several species of insects).
