Wingspan 7-12 mm.
A small, stubby-looking moth with a pale transverse band against a slightly darker brownish ground colour. A darker spot is visible beyond the band, and a dark suffusion before it.
The species is fairly common and widely distributed throughout most of the British Isles; the moths occur in July and August.
The larvae feed on a wide range of dried plant matter such as dead leaves and birds' nests, normally within a silken tube.
