Common in woodland throughout much of the British Isles, more numerous in the south. Abundant in Hampshire and on the Isle of Wight. Wingspan 7-9 mm. Very similar to P quercifoliella
, which see for differences. Although the imago is fairly regular at light, just as likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Oak, especially Evergreen Oak, Hornbeam, Beech and Sweet Chestnut.
