Description of adults: Examined: 2 . Forewing length: 6.5 - 6.8 mm. Head black; Vestiture of hair-like scales on the head of rusty colour, distad of eyes blackish-brown; face smoothly scaled, metallic greenish-golden to bronzy golden shining; eyes semiglobular, much enlarged in , 0.6 - 0.65 mm in diameter, approximated parietally; distance of eyes (frontally) about equal to diameter; labial palpi 0.6 - 0.7 mm long, very slender, dark brown with coppery shimmer and long distant black hair-like scales, slightly bent, directed ahead and slightly upwards; antennae in more than 2-times as long as forewing length, to half of their length brown with purple to bronzy golden glance, distad silvery-white with poor purple shimmer, basad with dense comb of erect scales; thorax and tegulae bronzy golden, anteriorly with purple to violet shimmer; forewings dark brown, devoid of distinct markings, bronzy golden shining, with purple shimmer especially along costa; fringe intensively bronzy golden shining; hindwing with broad scales completely covering the wing membrane, grey-brown with intensive violet tinge, costal margin indistinctly whitish; inner margin with broad, outer margin with slender belt of bronzy golden shimmer; fringe intensively bronzy golden shining; underside grey-brown, with intensive coppery to bronzy golden glance, the latter especially apically; fringe intensively bronzy golden shining; coxa of forelegs, as well as thorax laterally intensively metallic bronzy golden to greenish-golden shining; legs otherwise brown, bronzy golden shining, partly with intensive purple shimmer; foretibia with epiphysis; midtibia with a pair of spurs at distal end; hindtibia inflated, with long erect duft of hair-like scales and a pair of spurs each at about 0.5 of tibial length and at distal end; abdomen dark brown, with bronzy golden to coppery shimmer.


In Europe, the species is distributed from Spain throughout central Europe and Italy to Romania and Bulgaria. On the western Balkans, it has been recorded so far only from Bosnia and Albania. Furthermore, there is a doubtful record from the central part of European Russia (Karsholt & Nieukerken 2011). N. violella is also reported from the west Siberian plain (Dubatolov 2009).


Imagines fly in full sunshine on poor, also wet meadows. They are on the wing in one generation in July (Kurz & Kurz 2012).

The dark forewings with a somewhat oily appearance readily distinguish the species from all other European members of the genus. The species can be distinguished furthermore from Nemophora fasciella (Fabricius, 1775) by the absence of a violet cross fascia on the forewing. Females are separated from those of Nemophora cupriacella (Hübner, [1819]) by the presence of an epiphysis on the foretibia (Kozlov 2004).
