Status and distribution insufficiently known. Found in woodland in south-eastern England from Kent to Wiltshire and Dorset. First recorded in Hampshire in 1976, subsequently found at Ashurst and Botley Wood, but remaining very uncommon elsewhere in the county and on the Isle of Wight. Wingspan male 6.5-7.4 mm, female 7.2-8.5 mm. The speckled imago is distinctive with white thorax, black head and snow-white eye-caps, but more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines bark of Oak.
