Hyloniscus riparius
Riparian Woodlouse
A small woodlouse native to Central and Eastern Europe that has established invasive populations in North America since 1951 and is expanding eastward across Russia. It thrives in floodplain environments and can survive prolonged submersion. In invaded regions, it reaches high densities and may dominate local woodlice communities, potentially displacing native species.
