The black-and-white overview map shows Austria and its neighbouring countries; the detailed map segment is delineated. The blue circle indicates the site of the first detection of Ae. j. japonicus in Hungary in 2012; red circles mark further detection sites in Austria and Hungary in 2012, grey circles indicate sampling sites in which Ae. j. japonicus was not detected in 2012. Orange triangles indicate detection sites of the subspecies in 2013, grey triangles mark sampling sites in which Ae. j. japonicus was not detected in 2013. Black arrows point towards three “control sites”, i.e. sampling sites established at a certain distance to the first detection sites of the subspecies in Styria and Carinthia, respectively.
