Description of adults (Hannemann 1977): Forewing length: 9 - 15 mm. Vestiture of hair-like scales on the head dirty yellowish-white; antennae light brownish-yellow, in with long ciliae; forewings pale ochreous-yellow with brown dots and fascia-like spots; largest spots on costal and inner margin; fringe brown, four-times intersected whitish; hindwings brownish-grey.

Distribution:

Karsholt & Nieukerken (2011) record the species nearly from whole Europe, except for Iceland, Ireland and Sicily. Furthermore, records are known from the west Siberian plain and the south Siberian mountains (Dubatolov 2011), as well as from Japan (anonymous 2011a). In North America however, the species is missing (Hodges et al. 1983). Vertically, records are documented at least from about 400 - 1450 m Kurz & Kurz (2011).

Biology:

M. choragella has been found in beech-spruce-fir-mixed woods and on clear-cuttings, where the imagines are on the wing from June to August (Kurz & Kurz 2011). Larvae have been found in August and September. They overwinter. Following Hannemann (1977), the imagines rest on trunks of Salix, Populus, Tilia, Alnus or Picea, which have been infected by wood-fungi.

Larva. The larva is dirty whitish-yellow with dark brown head (Hannemann 1977). Following Petersen (1957), it lives in wood-fungi and rotten wood of Salix, Populus, Tilia, Fagus, Alnus and Picea. Larvae have been found gregariously in a wood-fungus, which was growing on dead wood of Fagus sylvatica (own observation).

Pupa. The pupa is light brown, thin-armoured and bears rows of posteriorly directed spines on the abdomen. With these, the pupa pushes itself halfway out of the feeding hole prior to hatching.

Genitalia (Petersen 1957). Uncus bilobed; tegumen slender with rounded vinculum; between lobes of uncus a broad, apically tapering chitinous rod, always clearly visible in opened genitalia; normally, this structure is situated beneath the rectum, tightly fitting to it; valvae very complex in structure, with a large dark chitinous tooth, heavily bent and itself occupied with small teeth; these secondary teeth vary not only from one animal to another, but also between both valves of the same animal; aedeagus large, medially bent, with numerous small teeth, slightly tapering.

Genitalia (Petersen 1957). Subgenital plate with four humps, the two medial ones with long setae; ostium burrowed; ductus bursae broad; apophyses normal; no signa detectable.

The species is very similar to Montescardia tessulatellus (Zeller, 1846), but is readly distinguished by the missing of the blackish spot on the discal crossvein, which is characteristic fot the latter species. In the genitalia of both males and females, the species are very different from each other.
