The leafhopper species Edwardsiana sociabilis (Ossiannilsson, 1936) and Laburrus pellax (Horváth, 1903) were recorded in Switzerland for the first time in the frame of an extensive invertebrate survey of 85 urban gardens in the city of Zurich. Both species are native to Europe and feed on the frequently cultivated ornamental plant genera Rosa and Aster, respectively. no significantly negative impact on the vegetation is currently known. Based on these and previous findings, our study indicates that surveying the invertebrate fauna in urbanized environments is important for the early detection of new species in a given geographic area.
