Local in saltmarshes, fens, wet heathland and freshwater marshes throughout much of England, Wales and southern Ireland. In Hampshire and on the Isle of Wight predominantly a species of coastal salt-marshes, and locally common in the south of the county and along the north coast of the Island. Wingspan 9-12 mm. Although extremely variable in wing pattern, the small size of this species and the olive-brown general coloration of the forewing and the reticulation in the distal area are characteristic [Bradley].
