Scheme of wing pattern:

Description of adults: Examined: 16 , 27 . Forewing length: 3.0 - 3.7 mm; 3.4 - 4.3 mm. Head black-brown; vestiture of hair-like scales on the head dirty white to rusty yellow; antennae dark brown, golden shining, 3/4 (), respectively, 4/7 () of forewing length; thorax bronzy golden, tegulae reddish bronzy golden, partly mixed purple; inner margin of forewing broad with bronzy gold extending from base nearly to median fascia; a broad bronzy golden fascia nearly at 1/4, connected with bronzy golden inner margin; rest of forewing reddish bronzy golden, more purple at costa and apex, in some specimens completely purple to purple-violet; wing markings whitish golden to golden, delicately bordered in bronzy gold: a narrow, slightly outwardly bent fascia nearly at 1/2 across the whole wing width, sometimes constricted anterior of middle and more golden coloured; rarely a small costal spot at 3/5; a slightly ovate spot at 3/4, seldom reaching outer margin but mostly reaching costa, sometimes a broader, golden fascia across the entire wing width, whitish golden coloured in anterior half of wing, somewhat narrowed in posterior third; fringe bronzy golden, somewhat purple shining, lighter distally; hindwing bronzy golden, apically with a purple tinge; fringe bronzy golden, lighter distally; legs and abdomen brown, golden shining.

Remarks. Individuals from the Alpes Maritimes (border between France and Italy, Marguareis, 2200 m) with golden colouration and fasciae at 1/2 and 3/4 absent or only weakly observable have been confirmed to belong to this species by genitalia examination (Zeller et al. 2007).

Distribution:

M. paykullella is distributed locally throughout the Alps and maybe also in the northern Apennines (locality uncertain, Kurz & Kurz 2012). Karsholt & Nieukerken (2011) record the species from France, Switzerland, Italy and Austria, with doubtful records from Germany (see also Osthelder 1951 and Pröse 1987) and Spain too. The latter are most certainly missidentifications of Micropterix aglaella (Duponchel, 1840). Records from southern Italy and Sicily (Meeß 1910) belong to Micropterix sicanella Zeller, 1847. The vertical distribution has been documented so far from near sea-level up to 2300 m a.s.l. (Kurz & Kurz 2012).

Biology:

Normally, the species occurs on clearings and outskirts of woodland, around bushes and dwarf shrubs in mountain regions (Kurz & Kurz 2012). Müller-Rutz (1927) for example, has found specimens feeding on blossoms of roses. Specimens without any markings however, were found above the timberline (2200 m) feeding on pollen of Helianthemum sp. in low grassland. Depending on the altitude, the imagines fly from May till July (Kurz & Kurz 2012).

Stages in development:

The early stages are unkown.

Genitalia. Uncus short, moderately broad, with broadly rounded tip; ventrally beyond uncus and inside tegumen, a tuft of longer hair-like setae; accessory claspers relatively broad, rounded distally; a row of about 10 longer, straight to slightly bent spinoid setae on inner surface of anterior end of accessory claspers, which are partly hook-shaped at their ends; proximally, a second row of two longer, nearly straight spinoid setae and three to four sickle-shaped thickened setae; valvae moderately long, constricted beyond middle, the last fourth enlarged, triangle-shaped and bent dorsad; a group of about five shorter spinoid setae and some setae on inner surface postbasally; one or two rows of about 10 shorter, straight spinoid setae and a row of longer setae on inner surface of the enlarged end of the valvae.

Genitalia. Tergite IX missing; sternite IX reduced, weakly sclerotized, with indistinct lateral margins; the pregenital abdomen noticeably but weakly differs from other species; terminal papillae with a sclerotized band, without any specific characteristics; ductus receptaculi very narrow at beginning of receptaculum seminis; receptaculum seminis relatively long and narrow, striated, somewhat enlarged in the second half.

M. paykullella is very similar to Micropterix aglaella (Duponchel, 1840), but shows a mostly more purple-violet colouration. The bronzy golden colouration at the base of the forewing nearly reaches the median fascia in M. paykullella, whereas in M. aglaella this colouration ends far before the median fascia. Here, the outer border of the bronzy golden colouration at the base and the median fascia are nearly parallel. Since M. paykullella and M. aglaella may occur together in the western Alps, for proper identification a genitalia examination is sometimes necessary. Furthermore, M. paykullella may be confused with Micropterix aureoviridella (Höfner, 1898) and the typical form of Micropterix sicanella Zeller, 1847, although the latter species does not occur within the distribution range of M. paykullella. M. paykullella can be separated from M. aureoviridella by its broader, bronzy golden fascia at 1/4, by its mostly narrower fascia at 1/2 and by its mostly stronger purple colouration especially at the apex. It can be separated from the typical form of M. sicanella by its bronzy golden colouration at the costa, which does not reach the base, by its narrower fascia at 1/2 and the mostly more intense purple colouration of the forewing, but also by mostly lacking a costal spot at 2/3. All above-mentioned species can easily be distinguished by their male genitalia.
Females of M. paykullella can be separated in their genitalia from M. aureoviridella and M. sicanella particularly by their distinctly slender and longer receptaculum seminis, and from M. aglaella by their distinctly stronger sclerotization of sternite IX and terminal papillae. Furthermore, M. aglaella has a slightly shorter and stouter receptaculum seminis. Females of Micropterix aruncella (Scopoli, 1763), which may be confused with the unmarked and bronzy golden forms of M. paykullella, can be easily identified by their characteristic sternite IX.

Phylogeny: With respect to the structure of the male genitalia, we do not know of any close relatives of M. paykullella so far.
