Yorkshire Status: Uncommon resident.

"More or less common, probably everywhere" said Porritt in 1907. It is probably not quite so common nowadays - we usually get 30 to 50 records annually. This is a woodland moth which rarely strays into gardens. It is rather patchily distributed across the county and is absent from what appears to be suitable woodland habitat in parts of central, northern and western Yorkshire. Numbers seem to be fairly stable.

Sutton & Beaumont, 1989: Rather sparsely reported from vice-counties 61 to 64. The records suggest a regular but not common woodland species but it may well be under-recorded due to the present-day emphasis on light trapping rather than sugaring or larvae collecting. The larvae are reported to be often quite common on birch in spring (PQW pers. comm.).
