Distribution:

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).

Biology:

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).
