Local in woodland, and on downland and scrubland throughout much of England. In Hampshire and on the Isle of Wight reasonably common and well-distributed, but largely absent from the New Forest. Wingspan 7.5-8.5 mm. Adults are day-flying, and the species is more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Dogwood, subsequently living within a movable case, over-wintering as a pupa. The mines are described in the following link:
