Distribution First recorded from Finland by Zatwarnicki and Kahanpaeae (2014) . Widespread in Europe; also known from North Africa and Pakistan ( Zatwarnicki 1988 , Zatwarnicki 2013 ). Ecology Larvae of this species feed on pondweeds ( Potamogeton ) ( Zatwarnicki 1988 ), the common frogbit ( Hydrocharis morsus-ranae ) ( Hering 1926 ), and possibly also on water plantains ( Alisma plantago-aquatica ) (see Deonier 1971 ).
