One of commonest species of Coleophora, in woodland, hedgerows, heathland and fens throughout much of the British Isles, except for the far northern islands of Scotland. In Hampshire and on the Isle of Wight common and widespread. Wingspan 10.5-14 mm. Like many of the Coleophora, imagines are virtually impossible to identify without recourse to dissection: the indistinct rings near the tip of the antenna help to distinguish it, but examination of the genitalia is required for positive identification of non-reared specimens.
The larva mines leaves of Birch, Alder, Elm and Hazel, living within a movable case, creating small mines which leave a characteristic pattern on the surface of the leaves of its foodplants, birch, elm, alder or hazel. Confusion can occur when it is occasionally found feeding on other trees, or on herbaceous plants onto which it has accidentally fallen.
