Found in modern times only in the fens of East Anglia (most recently in Suffolk and Norfolk).. Goater (1974) lists two records from the Brockenhurst, New Forest area, both over a century ago, and on the Isle of Wight, but not since 1973. Wingspan 7-8 mm. Resembles Parectopa ononidis but lacks two basal silver spots on the dorsum and has a conspicuous white apical spot, clearly visible on the underside (MBGBI Vol 2). Imago seldom encountered at light, and more likely to be recorded in the larval stage. Larva mines leaves of Common Comfrey and Lungwort, over-wintering as a pupa in a cocoon.
