Most records are of leaf-mines.

Sutton & Beaumont, 1989: Widely distributed and common in all five vice-counties.

2013 (CHF): Widespread and common across the county where the larva mine beech leaves. This is the commoner of the two beech-feedingStigmella species. The mine is usually very distinctive. The egg is laid under the leaf in the axil of a vein. The corridor then zigzags outwards between two lateral veins in the direction of the leaf margin. The frass is never coiled. It must be distinguished from Stigmella hemargyrella where the egg is laid away from the midrib, there is a section of coiled frass, and the mine is much more untidy.
