The dung fly Acerocnema macrocera (Meigen, 1826) is reported for the first time from both Belgium and the Netherlands. This remarkable species has a strict relationship with its host plants, Corydalis solida (Fumewort) and Corydalis cava (Stagger weed), two plants of which fruits are used to deposit eggs. Although reported as new, the species may have been present in both countries for a long time, but has been overlooked. The species is caught only occasionally due to the small size, early phenology and atypical habitat.
