Distribution and ecology. Holarctic species up to 1500 m.a.s.l. Inhabits standing and slow-flowing waters with a muddy substrate and plenty of vegetation. Tolerates moderate pollution, yet sensitive to prolonged droughts ( Welter-Schultes 2012). In Serbia, found in the Danube River, Srebrno jezero Lake, Ludaš Lake, Zasavica Wetland, and in Nišava, Jablanica and Južna Morava Rivers.
