An increasingly common immigrant from mainland Europe, appearing in southern England. In Hampshire and on the Isle of Wight there has been a marked increase in records, with between ten and twenty annually from 2006 onwards, compared with less than 30 in total between 1948 and 2005. Wingspan 28-36 mm. Most likely to be confused with second-generation Clay Triple-lines C. linearia, but antemedian fascia usually more continuous and media fascia thicker and bolder in Clay Triple-lines. Larva feeds on Evergreen Oak, no evidence of breeding in the UK.
