First recorded in our area from Teg Down, Winchester, in 1986, it was not found again until 2004 in the Fleet area, where the centre of population in north Hampshire still lies. The last decade has seen an increase in records and it is now frequently recorded around the Southampton area; first recorded from the Isle of Wight in 2020, where further expansion is likely. Wingspan 3.7-4.7 mm. Best recorded in the larval stage, when mines can be found in the leaves of Field Maple, sometimes Norway Maple, over-wintering as a pupa.
