Most records are of leaf-mines.
Sutton & Beaumont, 1989: Widespread and fairly common, recorded from all five vice-counties.
2013 (CHF): This is one of the commonest birch-feeding Stigmella species and is widespread across the county. It is easy to identify, as the first third of the mine is completely filled with distinctly greenish frass. After a moult, this pattern changes abruptly to a narrow black line which may follow a thick vein over a long distance though veins may be crossed.
