I conducted a survey of aculeate Hymenoptera in urban and suburban gardens of Brno-city in August 2015. For my survey, I selected three individual gardens, and in each of them chose three type of microhabitats: tree, grass and patch. I used yellow pan traps for taxon sampling. Using this method, I recorded 382 specimens belonging to 76 species. Subsequently, the basic indices of species diversity in individual gardens were calculated, and statistical analyses of individual gardens and various microhabitats were created. I report large differences between the Aculeata taxa found in urban and suburban gardens. Habitat preferences of species between microhabitats were discovered as well. Furthermore, I report 14 species mentioned in the Red List of threatened species of the Czech Republic (Straka 2005a,b) (hereinafter referred to as Red List); as well as one invasive species Isodontia mexicana (Saussure, 1867) and one species Pison atrum Spinola, 1808 recently reported as new for the Czech Republic (reported after the publication of the Red List itself).
