Range DescriptionThis species ranges throughout most of western, central and eastern Europe; populations are largely sympatric with populations of the parental species. It is absent from much of Scandinavia (although present in Denmark and southern most Sweden [it is unclear as to whether or not the Swedish populations are relicts or introductions]). In Italy it is present only with certainty in the River Po plain. The species has been introduced to the United Kingdom [not mapped here] and to Spain at Villasbuenas de Gata, Cáceres and unspecified localities in Galicia, Cataluña and Comunidad Valenciana. It is generally a lowland taxon which might occur up to approximately 1,550m asl.
