| Summary: | The biology of Hylochares cruentatus in Southern Finland is discussed. Contrary to previous observations in Russian Karelia, the species breeds in barkless willows along a regularly flooding small river in Southern Finland. The specialized biological requirements suggest this species might well survive in similar habitats in Eastern parts of Europe outside Russia. On the basis of existing information, this species is undoubtedly acutely threatened within the EU and potential breeding sites should be mapped, in Southern Finland aswell as in other Baltic regions. The distribution of Hylochares spp. across the Holarctic in combination with their habitat choice suggests they are one of the few eucnemids adapted into a life in Northern latitudes. |
