Description of adults: Examined: 4 , 2 . Forewing length: 5.8-7.0 mm; 6.0-6.1 mm. Head black brown; vestiture of hair-like scales on the head black in , dirty yellow to yellow in , respectively; face metallic greenish-golden shining; palpi directed ahead in , about 1 mm long, brown, bronzy shining on upperside, on underside with long, distant, beige and black bristles; in , palpi only about 0.6 mm long, hanging, otherwise like in ; eyes much enlarged in , parietally approximated, about 0.6 mm in diameter; distance of eyes (frontally) only about 0.15 mm; eyes in about 0.35 mm in diameter and distance about 0.7 mm; proboscis well developed, basally bronzy golden scaled; antennae in about 2-times the forewing length, filiform, purple to bronzy golden at basis, distally whitish; antennae in about 1 - 1 1/4 of forewing length, basally not thickened by erect scales, purple, whitish only at distal end; thorax and tegulae bronzy golden; forewing in relatively narrow, in somewhat broader; proximal 2/3 greenish-golden, distal part coppery to reddish-golden, separated by an indistinct black-violett cross-fascia; sometimes only basis of forewing greenish-golden, otherwise coppery to reddish-violett with black-violet cross-fascia; basis of inner margin dark brown to black violet; fringe reddish-golden; hindwings completely covered with broad scales, grey-brown, with intensive violet shimmer; fringe bronzy golden; underside grey-brown with intensive coppery, on hindwing violet shimmer; underside of thorax metallic greenish-golden; tibiae dark purple outwards, tarsi bronzy golden; foretibia with epiphysis; midtibia with a pair of spurs at distal end; hindtibia with long duft of hair-like scales, a long pair of spurs at about 0.5 of tibial length and a shorter pair of spurs at distal end; abdomen in tapering towards posterior end and flattened ventro-dorsally, bronzy golden on upperside, laterally and ventrally purple.

Variability (following Kozlov 2004): "The species is variable in forewing colour and in development of the fascia; in particular, southern populations are darker, with more expressed metallic tint of the forewing. The dark brown spot at the base of the R stem is also variable in size and can easily be overlooked in some specimens."

Distribution:

The species occurs from the Iberian peninsula and the British Isles throughout large parts of central, southern and eastern Europe (Karsholt & Nieukerken 2013). In Turkey, it is recorded from the provinces of Amasya, Bursa, Mersin, Malatya, Kahramanmaras and Van (Koçak & Kemal 2009), whereas Dubatolov (2009) doubtfully records it from the south Siberian mountains. Follwoing Stainton (1867), the species also occurs in Palestine (now Lebanon and Israel). Vertically, records are documented from near sea level to about 1300 m a.s.l. (Kurz & Kurz 2015).

Biology:

The species inhabits dry poor meadows and semi-arid meadows. The imagines fly in one generation per year from June to August (Kurz & Kurz 2015).

Diagnosis:

Diagnosis following Kozlov (2004): "The following species are most similar to N. fasciella:
  • albiciliellus, from which N. fasciella differs by the brown colour of the hindwing cilia, shorter labial palpi (palpus length 1.2–1.4 vertical eye diameter in males) and uniformly brown piliform scales covering the labial palpi;
  • violellus, from which N. fasciella differs by the presence of a fascia and by a metallic tint of the forewing;
  • barbatellus and N. mollella, from which N. fasciella differs by presence of a diffuse but distinct dark brown spot (diameter approximately equal to the width of fascia) near the tornal margin of forewing [at the basis of the inner margin], and the slightly larger size (forewing length 5.4–7.2 mm)."
