Local on waste ground and roadside verges throughout England and Wales, most numerous in the south, and local in Scotland. Probably under-recorded due to its similarity to other related species - and examination of a specimen in new areas is generally required for acceptance - it is known from a number of localities generally on the chalk. One in 2022 on the Island was the first since the 1930s. Wingspan 12-17 mm. One of the largest of the British species of Dichrorampha and distinguished by its comparatively broad wings and grey-brown appearance of the forewing [Bradley]. Larva feeds within roots of Mugwort.
