Scheme of wing pattern:

Description:. Examined: 19 , 32 . Forewing length: 3,9 - 4,6 mm; 4,2 - 4,8 mm. Head black-brown; vestiture of hair-like scales on the head brownish yellow to light ochre; antennae dark brownish golden with a light purple tinge, 4/5 (), respectively, 4/7 () of forewing length; thorax dark bronzy golden, posteriorly partly purplish, tegulae purplish violet, posteriorly sometimes with single bluish scales; forewing purplish violet, to some extent with single bluish scales, sometimes bronzy golden with a purplish violet tinge; markings golden, delicately bordered in bronzy gold and of variable width; an indistinct and minute bronzy golden spot at the base; a fascia near 1/4, slightly bent inwards and slightly narrowed at the costa or in the middle, sometimes not reaching the costa; a fascia at 1/2, equal in width, somewhat bent outwards and sometimes narrowed in the middle; at 3/4 a broad, more or less oval spot of irregular shape, mostly reaching costa but not inner margin; fringe whitish golden; hindwing bronzy golden, more or less with a purplish tinge; fringe bronzy golden, distally whitish; legs light brownish golden; abdomen golden brown.

Distribution:

According to Heath (1996) and Karsholt (2004), M. aureatella is distributed throughout Europe except Spain, Iceland, Luxembourg, Albania, Bulgaria, the European part of Turkey and the Mediterranean islands. Also Heath (1983) records this species throughout the Palaearctic region, except northern Africa (Heath 1983). The records from Portugal (Heath 1996) seem to be doubtful (Corley 2007).
Specimens have been found from near sea-level up to 1900 m a.s.l., being quite abundant above 1500 m a.s.l. in elfin woodland (Kurz et al. 2009).

Biology:

This species can often be found on high moor land with population of Vaccinium: Salzburg, Osterhorngruppe, Blinklingmoos, 2004.05.30 Salzburg, Osterhorn group, Strobl, Blinklingmoos, 2004.05.30 Salzburg, Osterhorn group, Strobl, Blinklingmoos, 2004.05.30 A is feeding on pollen of Pinus mugo mugo Turra: Salzburg, Radstädter Tauern, Obertauern, trail from the Gnadenalm to the Südwienerhütte, 2003.06.21

M. aureatella occurs preferably on acid soils like high moor land or edges of forest openings and forest tracks of spruce forests with underwood of Vaccinium myrtillus. In full sunshine, the moths feed on the pollen of Pinus mugo mugo, Aruncus dioicus, Rosa pendulina and Carex ssp.. If the animals also feed on Vaccinium myrtillus has to be proofed. Other Micropterix-species competing with M. aureatella on the above listed flowers are Micropterix aruncella (Scopoli, 1763), Micropterix aureoviridella (Höfner, 1898) and Micropterix rablensis Zeller, 1868.
The imagines are on the wing from May (more than 50 % of all records) to early August (only 1 record of 183, see Kurz et al. 2009), the flight period strongly depending on the altitude.

Stages in development:

According to Heath (1962 and 1983), the egg has an oval shape, a length of 470 - 530 µm and a width of 370 - 430 µm with rod-like structures. Immediately before hatching, the translucent white colour turns to grey. The larvae have been found in the strongly mycorrhizal leaf litter of bilberry plants and of oak and beech woodland (Carter and Dugdale, 1982). The pupa is unknown.

Genitalia. Uncus short, somewhat stout; ventrally beyond the uncus two unsclerotized small lobes bearing humps; between these and the accessory claspers two lobe-shaped appendices at the anterior margin with long hair-like setae, above them a row with shorter setae; accessory claspers long, narrow, spatulate, at the apex with a small dorsally oriented lobe with short spinoid setae; accessory clasper on the ventral margin with numerous, long, bent spinoid or sickle-shaped setae, which are ventrally oriented; valvae long, strong, constricted medially, with many setae postbasally; the last third bent upwards and distinctly enlarged with many spinoid setae (two clusters of spinoid setae, one at the point of inflection and one at the apex).

Genitalia. Tergite IX missing, sternite IX reduced, distinctly constricted medially, laterally enlarged into a lobe, strongly sclerotized, usually making the margins distinct. Terminal papillae with sclerotization in a band; receptaculum seminis long, narrow, at the beginning of the ductus receptaculi somewhat enlarged, forming a sac in the second half with typical striation; receptaculum seminis with a short appendix at the end.

From Micropterix aureatella shikotanica, the typical form differs only slightly. The former seems to have a slight golden glance along the inner margin, in the male genitalia, the uncus appears to be shorter (Kozlov 1988, 1989). M. aureatella can be separated from most other purple-violet and golden species of Micropterix by its lack of a golden inner margin of the forewing, the more regular golden fasciae as well as the lack of the small golden spot at the costa at about 3/5. Micropterix trifasciella Heath, 1965, also without this spot, usually has broader golden fasciae. In some cases M. aureatella and M. trifasciella can be separated only by examination of the genitalia. The type locality of M. trifasciella is in the area of Torino (Fenestrelle, Val Susa, the border region of Italy and France). Also Micropterix huemeri Kurz, Kurz & Zeller, 2004, found in the Alpes Maritimes (France), has a similar wing pattern. M. aureatella can also be separated with certainty by the male genitalia from the somewhat smaller species Micropterix rablensis Zeller, 1868 and Micropterix croatica Heath & Kaltenbach, 1984. Sometimes the costal spot of Micropterix allionella (Fabricius, 1794) can be missing and then it can be confused also with M. aureatella. Micropterix wockei Staudinger, 1870, occurring in Greece, also looks superficially very similar to M. aureatella.
The structures of the female abdomen (segment IX and X) of M. aureatella sometimes look similar to those of Micropterix aureoviridella (Höfner, 1898), but sternite IX of M. aureatella is normally more strongly sclerotized with thus more distinct lateral margins.
