distribution and habitat

The distribution of the species extends from some regions of France and the British Isles through Northern Europe and further east over Siberia to the Pacific Ocean . The animals are mainly found in raised bog areas. One focus of the habitat are coastal bogs. The species occurs sporadically in the Austrian Alpine foothills .

Way of life
