Sutton & Beaumont, 1989: Distributed over all five vice-counties and locally common although possibly under-recorded due to its late flight period. The larvae are sometimes conspicuous and have been recorded on hawthorn and blackthorn in the Scarborough area (PQW pers. comm.).
Current status (CHF, 2011): In decline nationally. A slow reduction in numbers. The moth is no longer resident at Spurn but otherwise the distribution has not altered.
