We surveyed butterflies and Zygaenidae in 25 reserves Prague, Czech Republic. A total of 85 spec. (47% of the Czech fauna) was detected, 22 of them of conservation concern. The richest sites were large, far from the city centre, on alkaline bedrocks, south- oriented, and hosting many vegetation types and plant species. We then used generalised linear models to fit responses of individual species to increasing urbanisation. Out of 60 species meeting criteria for the modelling, none responded positively to urbanisation, 20 responded linearly negatively (urban avoiders, mainly mesophilous species of rural landscapes), and 29 (suburban adaptable) peaked at the city periphery (mainly xerophilous specialists). Finally, 11 urban tolerant species did not respond to urbanisation at all. The fact that arboreal species persist even in urban parks, whereas common grassland species are absent there, implies that urban habitats might be increased by a more sensitive management of urban green spaces.
