Biology

Locally common on open seashore or lakeshore wetlands characterised by Potentilla palustris intermixed with large Carex species. Unlike Achalcus flavicollis (Meigen, 1824) and Achalcus vaillanti Brunhes, 1987, Achalcus nigropunctatus is only rarely caught in pure Phragmites stands.

Distribution

New to Finland. Previously found in the United Kingdom, Germany, Switzerland, France, the Czech Republic and Slovakia ( Drake 2008, Pollet 2009, Pollet 2013).
