Wingspan 9 to11 mm. Like other members of the genus, this species is very difficult to identify as an adult, and genitalia examination is recommended to be certain.

Adult Leafmine

Leafmine occurs on Hawthorn (also on Wild Service Tree) 

Various habitats, but particularly near hedgerows and areas with Hawthorn.

The adult moths are on the wing in two generations, during April and May and again in August.

The larval foodplant is Hawthorn, and the mine characteristics are quite distinctive. In its later stages, the larva folds over a leaf lobe to form a diagnostic cone.

Widespread and frequent in Britain. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as common.

Occasional in Leicestershire and Rutland. L&R Moth Group status = C (very scarce resident or rare migrant).
