Distribution:

N. betulinella is widely distributed in Europe, although we do not know any records from western and south-western Europe, from the Balkans and from the northern part of European Russia (Karsholt & Nieukerken 2011). The species has also been found in the south Siberian mountains (Dubatolov 2011). The vertical distribution is badly documented only (400 - 1050 m following Kurz & Kurz 2014).

Biology:

Besides the flight time of the imagines, reaching from May to July, no further biological data are available (Kurz & Kurz 2014).
