A rare and poorly known species, so far only known from the Netherlands ( Barendrecht 1938 ), Great Britain ( Chandler 1992 ), Norway ( Anonymous 2010 ) and Germany ( Plassmann 1988 ). The first record from the Baltic sea catchment area, new for Finland. Ecology Finnish sampling locality is a swampy lake shore with luxuriant vegetation.
