Nationally scarce (Na) 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, from South Gorley and Winchester in 2014, and another on the Island at Cranmore SSSI in June 2015. Wingspan 11-12 mm. Similar to C. syringella. Larva mines leaves of Ash and Wild Privet, subsequently living within a leaf-fold.
