Drosophila suzukii (spotted‐wing drosophila) spread rapidly during the first decade of the 2000s and then became widely distributed in Europe except for eastern countries. In Hungary, it was detected in 2012 for the first time, but its distribution in the eastern part of the country had been not studied. During the present investigation nine sampling sites in the north‐eastern part of the Carpathian lowlands belonging to Hungary, Ukraine and Romania were studied with baited traps. D. suzukii was detected in all seven Hungarian sites and in the one Western Ukrainian site where sampling occurred. Amongst the Hungarian sites, six had not previously been studied and the data provided here are the first for Western Ukraine and the second for this country following the published record from Yalta (Crimea, south‐east Ukraine).
