Scheme of wing pattern:

Description of adults: Examined: 9 , 10 . Forewing length: 3.4 - 3.9 mm; 3.8 - 4.2 mm. Head black; vestiture of hair-like scales on the head black-brown to black, slightly golden fuscous shining; antennae 4/5 (), respectively, 1/2 () of forewing length, dark brown at base, distal parts lighter brown, golden fuscous; thorax dark golden, posteriorly with purple and bluish scales; tegulae purple, posteriorly edged bluish; forewings golden with bronzy golden to reddish golden pattern, especially in the southern part of the geographic range the reddish golden markings often only faintly developed or, in males, almost oblique: a purple costal spot near base; a broad, diffuse fascia at 1/3, narrowing towards inner margin, sometimes disrupted near costa, sometimes purplish at the anterior margin and in the middle; a very broad, diffuse fascia at 3/4, purplish at costa, usually hardly distinguished from the bronzy golden apical part; cilia brightly golden; hindwings bronzy golden, especially at apex with purple tinge; cilia brightly bronzy golden with faint purple tinge; legs dark golden fuscous; abdomen golden brown.

Distribution:

According to Heath (1996) and Karsholt & Nieukerken (2011) the species occurs in northern, eastern, central and western Europe (including Great Britain and Ireland). Heath (1983) reports this species locally in northern Europe as far south as Bavaria (Germany). Meyrick (1912) depicts Europe, without further specification. Meeß (1910) reports the species from central, western (including England) and northern Europe. The records from Italy (Heath 1996; Hartig 1964) have not yet been proved and those from Portugal (Meeß 1910; Heath 1996) belong to the recently described Micropterix herminiella Corley, 2007. Vertically, records have been documented so far from sea-level up to 1000 m a.s.l. (Kurz & Kurz 2011).

Specimens have been collcted from flowering sedges (Carex ssp.) in open woodland (Fraxinus - Salix - association) at the border of fens. Klimesch (pers. comm.) found the species favoured swamplands, feeding on sedges in birch-groves. Deutsch (pers. comm.) reports its occurrence in a ditch with Alnus incana next to a small woody moorland slope. Imagines fly in one generation from the end of April till June, depending on height above sea-level and geographical latitude. The animals are day-active and have been found feeding at noon and crawling around till 19 p.m. (Kurz & Kurz 2011).

Stages in development:

Description of early stages following Heath (1962, 1983).

Egg. The egg has an oval shape, a length of 360–490 µm and a width of 260–330 µm, with up to 140 µm long, rod-like structures. Immediately before hatching, the translucent white colour turns to grey.

The larva and pupa are unknown.

Genitalia. Uncus moderately long, broad, stout, distally with some short setae; uncus forming a separate, clearly distinguishable unit with accessory claspers; accessory claspers moderately long, enlarged distally, anterior margin almost S-shaped, with short, stout thickened setae, which have spatulate bases and short, hook-like ends, pointing backwards; a row of shorter, unmodified setae near anterior margin; valvae rather short, stout, strongly narrowed near mid-length, with clearly distinguished ends; a small, basal group of short setae at inner surface, postbasally a larger, elongated group of short setae; several rows of very short to moderately long, spinoid setae at inner surface of distal ends.

Genitalia. Sclerites of segment IX reduced, forming a complete sclerotized ring: ventral half of normal width, ventrolaterally the proximal part lobe-shaped and enlarged; dorsal third of normal width, laterally slightly constricted; distal margin of ring with straight, sharp border, proximal margin of ring dorsolaterally irregular, faintly sclerotized; terminal papillae strongly sclerotized, distal margin straight, proximal margin irregular; ductus receptaculi short, sharply bent, very narrow at onset of receptaculum seminis; onset of receptaculum seminis slightly enlarged, upper third constricted and slightly bent; afterwards forming a curved and slender sac; lower end with characteristic, semicircular appendix.

The species might be confused with worn specimens of Micropterix tunbergella (Fabricius, 1787), or with reddish specimens of Micropterix calthella (Linné, 1761). It differs, however, from all European species except Micropterix herminiella Corley, 2007 and Micropterix aruncella (Scopoli, 1763) f. atricapilla Wocke, 1877 by the blackish scales on the head. The latter usually inhabits different biotopes (nutrient-poor meadows versus swampland) and is also found at higher elevations (although sometimes syntopic). The wing colour is greener in M. aruncella, having a distinct purple base at the costa. Adults are also usually smaller than M. mansuetella, with hair-like scales on the head less dark. M. herminiella on the other hand, is allopatric to M. mansuetella to present knowledge, inhabiting only the Iberian peninsula. Seldom, also unmarked specimens of Micropterix myrtetella Zeller, 1850 may have blackish scales on the head, but this species is much smaller than M. mansuetella and therefore readily distinguishable.

Phylogeny: The presence of rudimentary sclerotization at the dorsum of segment IX in the female postabdomen is regarded to be plesiomorphic and is unique among all other known species of the genus. Also in the male genitalia, the absence of strongly modified setae at the accessory claspers seems to reflect the more primitive situation within the genus. Therefore, M. mansuetella is regarded tentatively to be one of the most primitive members of Micropterix Hübner, 1825.
