Since 2014 Drosophila suzukii can be found in Southern Sweden. Here, during the last years, flies could be trapped almost during the whole year and built up high population densities between July and October. The flies are common in commercial production sites, private gardens as well as in forests. Since 2018 we investigate the dispersal of the flies with support by citizen scientists.
