Sutton & Beaumont, 1989: Widespread and fairly common, recorded from all five vice-counties.
2013 (CHF): Widespread across the county but rather local. Identifying Stigmella mines in hawthorn can be tricky at times and this species can be mistaken for several others. The egg is on the underside of the leaf or on the petiole. The early gallery follows the petiole or a vein and is filled with brownish frass. The second part often has a section of coiled frass. It then widens into a secondary blotch. The mine is constrained between two veins or, less frequently, a lateral vein and the leaf margin. In the pseudoblotch the frass is warm brown and coiled. The larva is yellow. The mine may be difficult to distinguish from Stigmella crataegella which has a green larva, a thinner initial gallery and more prominently coiled frass with more hairpin turns.
