Common in woodland, scrub, heathland and gardens throughout the British Isles. Widespread and common in Hampshire, but rather scarce on the Isle of Wight, with just two records there so far this century. Wingspan 25-34 mm. The main confusion species is Satin Lutestring Tetheella fluctuosa
, but differs, for example, in small apical dash, which originates at the apex in Common Lutestring and some way down the costa in Satin Lutestring. Larva feeds on Silver and Downy Birch, over-wintering as a pupa.
