    Identification difficulty

    Adult Leafmine  

    Recording advice

    Adults: It may not be possible to identify adults to species level and gen det would be essential.

    Leafmines: Please provide photographs to support your record and add a note of the host species in the ‘Comments’ section when submitting a record. It is essential to note the egg position and, if the larva is present, to include a photograph of the larva.

    Habitat

    Wherever Oak is present.

    When to see it

    The larva mines leaves of oak (Quercus robur) in two generations, during June and July and again in October and November. Adult moths fly in May and June and again in August and September.

    Life History

    Larvae feed on Oak.

    UK Status

    The distribution of this species is still imperfectly known, due to confusion with other oak-feeding species, in particular S. atricapitella, but it seems to be widespread and fairly frequent in Britain. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as common.

    VC55 Status

    Infrequently recorded in Leicestershire and Rutland.
