In Europe, the species is known only from Sweden, Finland and the northern part of European Russia (Karsholt & Nieukerken, 2010). In Asia, it has been recorded from the west Siberian plain, the south Siberian mountains, from Magadan, the Amur and Primorye regions and from the Kuriles (Dubatolov 2009). Furthermore, it also occurs in Japan (anonymous 2009a), but is absent from North America (Hodges et al. 1983). The species is also found in Korea (Kozlov 2004).
The species is very variable both in external characters (head colour, width of fascia, length of apical yellow stripes) and in the male genitalia (shape of valva, tegumen, and base of aedeagus, see Kozlov 2004). Externally, it is very similar to Nemophora degeerella (Linné, 1758), Nemophora bellela (Walker, 1863) and Nemophora congruella Zeller, 1839, but it is distributed allopatrically from the latter species. From both other species, it is best distinguished by the narrow forewings and the medial fascia, which is located more apically in N. amatella. Furthermore, the lateral violet lead-like segments of the fascia are only one third in width compared to the central yellow segment in N. amatella, whereas in N. degeerella and N. bellela, they are at least half as broad. Furthermore, N. bellela has distinctly shorter antennae in males (only twice as long as the forewing), the fascia is constricted distinctly in the anterior half and the general colouration of the other light markings is darker brown.
