This species was described new to science in 2002 and belongs to the Elachista cingillella complex. After investigation by L. Kaila & J. Junnilainen, this complex consists of 6 valid species. All references to Elachista cingillella from southern Europe and Belgium in fact concern Elachista metella.
Recorded from the province of NA as Elachista cingillella based on three male specimens which were caught at Belvaux on 26.v.1980, leg. & gen. det. G. & W. De Prins. During 2019 a further specimen was collected near Resteigne (LX).
Hitherto a very rare and local species.
It varies considerably in size, individuals of the autumn brood being often smaller than those flying in early summer. Wingspan from 6.5–9.1 mm.
Wings consisting of grey, dark tipped scales giving it a mottled appearance with in the middle of the wing an ochreous white transverse fascia, extended from costa to dorsal margin.
Since there are many black-grey species with a white transverse fascia, control of the genitalia is necessary for identification.
