Yorkshire Status: Fairly common resident.

This is a widespread species across the county but can be rather local. Identifying Stigmella mines in hawthorn can be tricky at times as there are a number of contenders, and this species can be mistaken for several others. The egg is on the upperside 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 usually has a rather characteristic 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, and usually abruptly turns back on itself at times. 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. The key at More Info is useful in separating these species.
