Common in fens, damp meadows and marshes throughout much of the British Isles. In Hampshire almost certainly under-recorded within other Juncus-feeding species, but recorded from areas such the New Forest, Botley Wood and Pamber Forest; recent work has found it to be relatively frequent in the west of the Isle of Wight. Wingspan 9-12 mm. Like many of the Coleophora, imagines are virtually impossible to identify without recourse to dissection, and best recorded by searching for the larvae, which live in cases of characteristic form on seeds of Jointed Rush and Sharp-flowered Rush.
