Common in dry grassland throughout much of England, Wales and south-eastern Scotland. In Hampshire and on the Isle of Wight widespread in all three vice-counties. Wingspan 10-16 mm. Day-flying. Quite distinct amongst the Glyphipterix species by reason of its plain brassy forewing and straight termen, the latter distinguishing it from plain forms of G. thrasonella (MBGBI Vol 2). Larva feeds within stems of Field Wood-rush.
