Most records are of leaf-mines.
Sutton & Beaumont, 1989: Widespread and usually common to abundant, recorded from all five vice-counties.
2013 (CHF):A very common and distinctive leaf mine which is not likely to be confused with any other species mining on birch. The mine is a roundish, often almost circular, primary, upper-surface blotch without a trace of an initial corridor. There are often several mines in leaf. The mine has a conspicuous dark centre, where the larva often retreats. Young mines consist of only the dark centre, without the light periphery.
