Scarce in Britain as far north as Perthshire and in Ireland, especially on sea-cliffs and rough ground near the sea and woodland inland. Very rare in our area: Ffennell reported one from the Southampton area in 1935, and there are three old records from the Isle of Wight. Recent years have seen a scattering of further examples, with the first for North Hampshire coming in 2020. Wingspan 11-12 mm. Beware confusing the far more widespread and common
C. syringella. Larva mines leaves of Ash and Wild Privet, subsequently living within a leaf-fold.
