Distribution

European, mainly nemoral, recorded from Ireland, Britain, the Netherlands, Belgium, Germany, Poland, Czech Republic and Estonia ( Chandler 2004). Few records are known from the Nordic region, from Denmark ( Petersen and Meier 2001), Sweden (only a single record, Kjaerandsen et al. 2007), and from Norway, without indication of the collecting locality ( Rindal et al. 2008). In Finland the presence of the species was based on Hackman’s ( Hackman 1980) checklist. However, the original sources of that record are unknown. In fact, the only exemplar in the MZHF collection " Diptera Fennica" identified as Orfelia pallida actually belongs to Macrorrhyncha rostrata Zetterstedt. New for the Republic of Karelia.

Ecology

The Finnish record is from a herb-rich, spruce dominated forest site adjacent to a sea gulf and a wet meadow with moist black alder stands. Huge willows ( Salix ) and plenty of dead wood are present as well. Karelian records are from herb-rich deciduous forests and a black alder fen. Immature stages are unknown.

Conservation

Due to the ambiguous occurrence data, the species was not included in the 2010 Red List of Finnish species. However, it is likely that Orfelia pallida is very rare in Finland and perhaps confined to hemiboreal deciduous forests.
