For the county, we have a total of 110 records from 100 sites. First recorded in 1883.
Most records are of leaf-mines.
Sutton & Beaumont, 1989: Recorded fairly commonly from all vice-counties.
2013 (CHF): This is a common species across the county, the larvae mining leaves of birch. The early gallery is strongly contorted and coils closely around the egg. The later part is much straighter and often follows a vein. The frass occupies one third to one half the width of the gallery. The mine differs from the much less common Stigmella betulicola in that the sides of the corridor are irregularly scalloped out and there is usually no more than one mine per leaf. Mines are often found quite late in the year and can occupy green "islands" in the leaf.
