Distribution

Holarctic, widely distributed in Europe ( Chandler 2004). Wide range in Sweden ( Kjaerandsen et al. 2007) and in the Republic of Karelia ( Polevoi 2013a). In Finland mainly collected from the southern parts of the country, except for an old record from NW Lapland, Muonio ( Lundström 1914).

Ecology

New records from Lapland are mainly from calcareous spring fens and rich fens, but also from headwater streams with rich riparian vegetation. In the light of these new records Isoneuromyia semirufa (Fig. 2) is perhaps not confined to forest habitats, but may also thrive in peatlands. Immature stages are unknown.

Conservation

Red-listed in Finland (NT, Penttinen et al. 2010).
