Description of adults: Examined: 1 . Forewing length: : 7.1 mm. Head black-brown; vestiture of hair-like scales on the head distant, dark yellow; frons smoothly scaled, bronzy golden shining; labial palpi short, only slightly longer than the diameter of an eye, yellow, golden shining, with single black-brown setae and a pointed terminal segment; eyes small, about 0.3 mm in diameter; distance of eyes (frontally) greater than the diameter of an eye; antennae in the male filiform, with inflated scapus, about 2 1/4 of forewing length; dark brown from basis to about the median fascia in the forewing, distally greyish white; about 7-9 basal segments of the antennae each with an inwardly directed, small spike; thorax and tegulae bronzy golden; forewings elongate, only hardly becoming broader towards the apex, with pointed apex and dark brown ground colour; proximal half of forewing mostly yellow, costal and inner margin, as well as longitudinal stripes between the veins of variable width blackish-brown with lead-like glance and partly purple shimmer; distad of 1/2 a three-segmented fascia across the whole wing width; the central segment narrow, yellow, the lateral segments even narrower, with lead-like glance, purple shining; all three segments delicately bordered black-brown; distad of this fascia first a yellow, then a lead-like shining and finally again a yellow elongate spot across about 1/3 of the wing width, all three delicately bordered black-brown and increasingly outwardly oblique towards costa; apex with a faint, lead-like shining spot; fringe consisting of two rows of scales, the inner row dark brown, purple and lead-like shining, the outer row of double width, dark brown, partly light golden shining; hindwing with very broad scales, completely covering the wing membrane, violet-brown, with a delicate bronzy golden line along the basis of fringe; costal margin diffuse yellowish lightened from base to about 2/3; fringe consisting of two rows of scales, the distal scales 3 - 4 times as long, dark brown, bronzy golden shining; underside of forewing dark brown, markings of upperside only weakly shimmering through except for the distalmost yellow spot, which is distinctly developed; underside of hindwing violet-brown, golden speckled along margin, at apex and at tornus; legs golden yellow at one side, brownish-violett at the other side; hindtibiae light golden yellow with long hair-like scales; hindtarsi ringed light and dark; foretibia with epiphysis, inserted in the middle of the tibia and only hardly reaching its distal end in length; midtibia with a pair of spurs at the distal end; hindtibia with a pair of spurs each at about 0.6 of the tibial length and at the distal end; abdomen dark brown with scarce, weakly golden shining scaling.

Distribution:

In Europe, the species is known only from central Europe, northwards to Denmark, eastwards to Romania (Karsholt & Nieukerken 2010). Furthermore, it has been reported in the northern Palaearctic region from Japan (anonymous 2009a), from the south Siberian mountains, the Amur and Primorye regions and from the Kuriles (Dubatolov 2009). Vertical records are scarce and reach from 400 - 1500 m a.s.l. (Kurz & Kurz 2011).

Biology:

 
The edges of mixed beech-spruce-fir-woods on calcareous ground are an example of the biotope of the species: Salzburg, Osterhorn group, Wolgangsee, Falkensteinwand, Scheffelblick, 2004.06.06 : Salzburg, Osterhorn group, St. Gilgen, Falkenstein, Scheffelblick, 6.6.2004 the same animal: Salzburg, Osterhorn group, St. Gilgen, Falkenstein, Scheffelblick, 2004.06.06

N. ochsenheimerella has been found at sunny edges of mixed beech-spruce-fir-woods in mountain areas with adjacent poor meadows. Here, the imagines were on the wing in May and June (Kurz & Kurz 2011).

Diagnosis:

Due to its characteristic wing pattern, N. ochsenheimerella cannot be confused with any other species, although the yellow spots in the distal part of the wing are highly variable and may be confluent as well. Melanistic specimens have been confused with Nemophora degeerella (Linné, 1758), although they are much smaller (Kozlov 2004).
