Description of adults:: Examined: 1 . Forewing length: 8.0 mm. Head dark brown; vestiture of hair-like scales on the head dirty whitish-yellow; eyes semiglobular, 0.3 mm in diameter; distance of eyes (frontally) 0.6 mm; maxillary palpi scaled beige; labial palpi tiny, 0.3 mm in length, straight, diverging ahead, brownish, bronzy golden shining; antennae only about 2/5 () of forewing length, filiform, dark brown; thorax and tegulae olive brown, bronzy golden shining; forewing elongate, unicolorous, olive brown, bronzy golden shining; fringe of same colour; hindwing with broad scales, almost completely covering wing membrane, its colour similar to forewing, slightly more greyish; fringe olive brown, bronzy golden shining; underside like upperside; legs dark brown, bronzy golden shining; foretibia with epiphysis; midtibia with a pair of spurs at distal end; hindtibia with a pair of spurs each at about 0.6 of tibial length and at distal end; abdomen flattened laterally, dark brown with olive brown scaling and bronzy golden shimmer.

Distribution:

Except Portugal and Ireland, L. fuscatella has been recorded from western, central, northern and northeastern Europe, as well as from the northern Balkans (Romania, see Karsholt & Nieukerken 2004). The species is known also from Siberia, from the Amur and Primorye regions (Dubatolov 2009).

Stages in development:

Egg. Oviposition has not been observed.

Larva. Following Meeß (1910), the larva is whitish with black head and small brown prothoracic plate. When the leaves have fallen, the larvae can be found in more or less spherical galls in 3 - 13 mm thick twigs of Betula-species. The galls are mostly found 1 - 1.5 m above the ground, usually at adjacent nodes. The larvae overwinter in the galls and in spring they make an operculum. Inside the gall, pupation takes place in a thick, white cocoon (Heath & Pelham-Clinton 1983, Pellmyr 1996).

Diagnosis:

Externally, Lampronia morosa Zeller, 1852 is quite similar, but normally it is smaller than L. fuscatella, the yellowish-white spot near the tornus is distinctly developed (missing in L. fuscatella), the vestiture of hair-like scales on the head is brown instead of yellow.
