Sutton & Beaumont, 1989: Widespread and often common in all five vice-counties.
2013 (CHF): Locally common in oak woodland across the county. This species also feeds sometimes on sweet chestnut. The leaf mines are characteristic and are a white upper-surface blotch which becomes pale brown with age. Frass is ejected through a slit in the upper surface and there are often several mines in one leaf. Pupation takes place within the mine. Many records are of adults coming to light. The adult is golden-brown with darker speckled tips to the wings.
