Aphanotrigonum brachypterum?

That's not (yet) on the Dutch species list, but the name sounds good.

Chloropidae: Conioscinella zetterstedti Andersson, 1966, in earlier times identified by many authors as "C. brachyptera (Zetterstedt, 1848)" but not identical with Aphanotrigonum brachypterum (Zetterstedt, 1848). A typical species in marine dunes covered with Ammophila arenaria; Europe until Siberia and Kamchatka, North America. Mass occurrence in Barber traps among Ammopgila tussocks. A detailed article: Brauns, A. 1938: Die Flügelrückbildung bei der Strandfliege Conioscinella brachyptera Zett. (Diptera; Chloropidae) und die Beziehungen zur Ausbildung der Flügelsinneskuppeln. - Zoologischer Anzeiger 123(10-12): 281-295.

Wheler, Terry A. 1994. Conioscinella zetterstedti Andersson (Diptera: Chloropidae), a chloropid fly with polymorphic wing reduction, new to the Nearctic and central Palaearctic regions. Canadian Entomologist 126(6):1377-1381.

"Although previously known only from supralittoral areas on the shores of the North and Baltic seas, collection data in the Nearctic and central Palaearctic regions indicate that C. zetterstedti may be abundant in various decay communities including peatlands, swamps, lake shore debris, mammal nests, forest leaf litter, and around the bases of vegetation."
