Distribution and ecology
. Holarctic species up to
1100 m
.a.s.l. Inhabits stagnant and slow-flowing waters rich in vegetation. Does not tolerate droughts (

). Rare in
Serbia
, it was recorded in the Danube, Jezava and Plazović Rivers, and a small pond near the Nera River (
Bela Crkva
Municipality).
Other remarks
