Sutton & Beaumont, 1989: A widespread and common moth in all five vice-counties.
2013 (CHF): Widespread and common across the county where the larvae mine beech leaves. It tends to be not quite as common as Stigmella tityrella. The two species are usually easy to distinguish. The egg is usually on the upperside of the leaf fairly close to the leaf margin. The mine is an untidy corridor running in the vague direction of the midrib and often crossing a vein. In the middle section there is always a section of coiled frass and this is one of the easiest features to distinguish the two species. The mine of tityrella is a much tidier zigzag mine leading from the midrib outwards.
