Wingspan 7 to 8 mm. Best recorded from the leafmine.  The larva mines the leaves of Wild Cherry and Dwarf Cherry

Adult Leafmine

In areas where the larval foodplants occur.

In common with a number of other Phyllonorycter species, the species is bivoltine, with adults flying in May and again in August.

The larva feeds in a blotch on the underside of a leaf of Cherry (Prunus spp.), including cultivated versions as well as Wild Cherry (Prunus avium) and Dwarf Cherry (Prunus cerasus).

Distributed mainly in the southern half on England where this species can be locally frequent at times. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.

Once thought uncommon in Leicestershire and Rutland, it is now found more regularly by recording the leafmines on Cherry.
